heath bar blondies

by jenna on February 3, 2011

As much as I love all things chocolate, sometimes (sometimes!) it’s nice to take a teeeeeny little break.

You have no idea how hard it was for me to not add chocolate chips to this already decadent, ooey gooey chewy blondie recipe. Every time my hand naturally gravitated towards the bag of chocolate, I just ate more heath bar bits.

It was worth it.

These blondies are by far one of the best things to come out of my teeny tiny little kitchen (by the way I’m moving! But to a little house that still doesn’t have a dishwasher or a garbage disposal). They’re perfectly chewy and rich, and absolutely stuffed with delicious toffee bits and walnuts.

And who doesn’t love toffee??!

It practically makes up for the lack of chocolate.

If you bring one dessert to any Super Bowl party, this should be it. They’re so good that after baking them, I stood over the pan in my still sweaty yoga clothes and ate all of the edges off of all 16 blondies.

And then I ate all the crumbs.

And then I took a bite of one.

And then I ate the whole thing because who just “takes a bite” out of a blondie?


Browning the butter really puts these blondies over the edge. Like these chocolate chip cookies, it gives them an almost nutty, caramelized taste…perfect for adding tons of toffee!

And I can’t even believe I’m saying typing this, but I kinda think I might even like them better than their brownie cousin.

Of course I’ll probably retract that statement next time I bake a batch of warm fudgey brownies.

But for now, all I can tell you is that these really are mind-blowing delicious. My favorite part is how chewy they are! And how easy they are to make, of course. Although that could be potentially dangerous when it comes to late-night blondie cravings.

We’ll cross that road when we get there.

Heath Bar Blondies

makes 12-16

adapted from Smitten Kitchen

Print this recipe!

1 stick butter

1 cup packed dark brown sugar

1 egg

1/2 tsp salt

1 tsp vanilla extract (or the seeds of one vanilla bean)

1 cup all purpose flour

1/2 cup heath bar crumbles

1/2 cup roughly chopped walnuts

Preheat your oven to 350 and butter an 8-inch square pan.

Brown your butter by melting it over medium heat on the stove until it becomes a golden caramel color (see here for more tips). Be careful not to burn the butter—you only want to brown it. This will take several minutes and it’s easiest to keep swirling the pan with your hand while it browns.

Pour the browned butter into the bowl of a kitchen aid and add the brown sugar. Beat for about four minutes, until creamy. Add the egg and beat again. Then, add the flour, salt and vanilla extract (or seeds). Beat until combined.

Fold in the heath bar bits and chopped walnuts. Spread out mixture in your buttered pan and bake for 25 minutes, or until edges begin to pull away from the sides of the pan.

Let cool before slicing into squares.

I would really like to consume mass quantities of these today.


Molly February 3, 2011 at 5:05 am

1. All day while I speak about weight loss and diabetes I will be thinking about Health Bar Blondies.
2. I think you move more than I do which makes me feel good knowing I’m not the only one that goes ahead and saves their packing boxes because they will be needed soon enough!


megan @ blackberries for jam February 3, 2011 at 5:05 am

I should definitely make these for the Superbowl. But I think I need to make them today to, you know, make sure they’re good πŸ™‚


Kristen @ That Hoosier Girl February 3, 2011 at 5:08 am

My mom would LOVE me if I brought this to the Superbowl party! Slightly warmed and topped with vanilla bean ice cream??? Heaven!


kristy @ kristyruns February 3, 2011 at 5:30 am

Omg. I can’t wait to make these the next time we have friends over! P.s. I don’t have a microwave or garbage disposal …it’s not so bad. πŸ˜‰


Kristina February 3, 2011 at 5:37 am

Deb’s Blondie recipe is my absolute favorite! (p.s. I also like blondies better than brownies… my evil little secret).


Jessie February 3, 2011 at 5:40 am

Heath bars are my favorite. Can’t wait to try this recipe, good thing its Thursday and the weekend will be here soon!


Estela @ Weekly Bite February 3, 2011 at 5:42 am

If it has Heath Bar in it, I’m sold!



Teri @BeePie Runs February 3, 2011 at 5:43 am

Oooohh! I have GOT to stop reading your blog before I’ve had breakfast. On the plus side, these look fabulous and I’m definitely gonna try them – maybe for breakfast tomorrow πŸ™‚


Tracey @ I'm Not Superhuman February 3, 2011 at 5:44 am

Dear Jenna,

Please come be my personal chef. Bring your heath bar blondies.

Hungrily yours,


jenna February 3, 2011 at 8:11 am

Ok! You make dinner and I’ll bring dessert πŸ™‚


Eliz@The Sweet Life February 3, 2011 at 5:44 am

Two of my favorite things, together at last!!!


Evan Thomas February 3, 2011 at 5:45 am

I need these in my life like I need water and oxygen.


Bethany @Bridezilla Bakes February 3, 2011 at 5:50 am

For a second, I thought the title of this post was “health bar blondies.” Blech, thought I. Who puts a health bar in a blondie?

….And then I realized you would never do such a thing. These look AWESOME! Bars are so fun. They remind me of elementary school bake sales — in the best way πŸ™‚


Amy February 3, 2011 at 6:01 am

Bethany, I love this comment– I read the title the same way– too funny!

Jenna – this look incredible (I’m totally drooling on my keyboard as I type this…) It needs to be the weekend all ready so I can get my bake on πŸ™‚


Beth February 3, 2011 at 6:17 am

Haha, I read it the same way! But these look so ooey gooey delicious. Totally making them this weekend!


jenna February 3, 2011 at 8:08 am

hah!! That’s funny!


Bethany @Bridezilla Bakes February 3, 2011 at 1:19 pm

Also, what IS a health bar??? There are energy bars, nutrition bars, etc… but I don’t even think a health bar is a real thing.


jenna February 3, 2011 at 1:40 pm

hah! You are so right.


Justeen @ Blissful Baking February 3, 2011 at 6:06 am

Oh my gosh, these look AMAZING! I am a huge chocolate-lover myself, but sometimes I REALLY enjoy a nice, buttery blondie!


chelsey @ clean eating chelsey February 3, 2011 at 6:10 am

I’ve always been a chocolate girl, but recently that has changed. These blondies may change my outlook on life.


Jennifer (take the day off) February 3, 2011 at 6:11 am

I have been looking for a blondie recipe without chocolate chips, believe it or not. This is the next recipe that will come out of my little kitchen, I assure you. I cant wait to make these! (and i definitely do the eat the edge thing too, shameless)


Lauren at KeepItSweet February 3, 2011 at 6:12 am

Heath and ooey gooey? Yes these look delicious!!


sonia February 3, 2011 at 6:13 am

THese are wonderful blondies, looking and tasting good even without chocolates… !


Katie February 3, 2011 at 6:16 am

I LOVE blondies! I actually hate chocolate so I always make blondies. (Plus, I’m a blonde πŸ˜‰ ). Never thought to put heath in there. I want to try this recipe because the one I have is good but honestly difficult to get the timing right for some reason.


Ashley February 3, 2011 at 6:16 am

I have far too many times stood over a pan of brownies picking and eating before anyone else even sees them. YUM.


Danielle February 3, 2011 at 6:18 am

Do you know that I’ve never made the blondie plunge because warm, fudgey brownies always win? No. Oh. Well I haven’t πŸ™‚ but these may be just the thing for me to take that chance. Sounds like a phenomenal recipe!


The Blue-Eyed Bakers February 3, 2011 at 6:19 am

Oh those Heath bar bits…they’re amazing. They make all your troubles go far far away. And these blondies? They could do the same thing from the looks of them.


Angela @ Eat Spin Run Repeat February 3, 2011 at 6:20 am

I’d like to eat 10 of these. Well, actually, because they’re health bars, let’s make that 20.


Nicole February 3, 2011 at 6:21 am

Oh, wow! That’s incredible. These look amazing!


Shannon @ Freshman Yr of Life February 3, 2011 at 6:22 am

Literally my glands just salivated. I might have to make these accompanied by the buffalo chicken wontons for the super bowl party. hmmm


Ella February 3, 2011 at 6:23 am

YUM! …must…make…asap…


Natalia - a side of simple February 3, 2011 at 6:30 am

While chocolate steals my heart, I love those one night stands that turn into “whole batch” relationships with blondies. It’s just one of those relationships πŸ˜‰
Plus, browning butter is never wrong. Never.


jenna February 3, 2011 at 8:06 am

I love everything about your comment. You know what’s up!


Liz @ Tip Top Shape February 3, 2011 at 6:31 am

Ooh, these look fantastic!!! I love Heath bars, and I bet they would be delicious in blondie form!


VeggieGirl February 3, 2011 at 6:32 am

Blondies! My specialty, as you know πŸ˜€


Baking 'n' Books February 3, 2011 at 6:36 am

Haha – I like the “retract” statement πŸ™‚

Your moving? Your own house?! How come?


jenna February 3, 2011 at 8:06 am

because my lease is up and it’s a cute house!


Becky February 3, 2011 at 9:06 am

You move more often than some college students change their sheets!


Baking 'n' Books February 3, 2011 at 12:05 pm

Oh I bet you I could beat you on the moving – TRUST me!

Is it your own little house though? Or renting from owners?…A real kitchen?!

…also had to comment that I put Chocolate-Chips in EVERYTHING! – So I have no idea how you managed to abstain….I even put it in Cornbread I made…;)


Susan February 4, 2011 at 1:39 pm

Still in SR? What neighborhood? If we’re neighbors, I’ll wash dishes in exchange for baked goods! πŸ™‚


Maria February 3, 2011 at 6:37 am

It’s official: I’m moving in with you so I can chomp on all of these delicious treats!


Stacie @ Imperfectly Healthy February 3, 2011 at 6:41 am

Ahhh! I love toffee! These look delish! It’s a huge debate in our house because I like blondies more and my husband likes brownies more – what to do!


jenna February 3, 2011 at 8:05 am

make both! Obviously!


Gill (snaxandthecity) February 3, 2011 at 6:43 am

wow. i wish we had the superbowl here just so i could make these! get in my belly.


Dani February 3, 2011 at 6:47 am

Jenna! What are you trying to do to us? OMG, those look SO good!


Michelle February 3, 2011 at 6:56 am

Dang, those look incredible! I’m pretty sure they’d be gone in a second if I brought them to our Superbowl Party. I’m on it…


jenna February 3, 2011 at 8:04 am

do it! And let me know how it goes πŸ™‚


dana February 3, 2011 at 7:06 am

Yikes! Those look delicious. You’re so creative in the kitchen : ) Thanks for sharing!


Jil @ Big City, Lil Kitchen February 3, 2011 at 7:10 am

Ohhh, love toffee!! These sound absolutely incredible!


jen @ taste life February 3, 2011 at 7:11 am

Better than brownies??? I might have to give these a whirl.


Lindsey T. February 3, 2011 at 7:19 am

I’LL admit it… I definitely like gooey blondies more than brownies πŸ™‚


Marie @ Peonies&Cupcakes February 3, 2011 at 7:23 am

Ohhh these babies look sinfully good!!


Stephanie @ Living and Loving February 3, 2011 at 7:35 am

Dear Jenna,

I live in Austin. Please deliver a big ol batch of these to me πŸ˜‰ k thanks. I’m glad we talked about this.



Current Instincts February 3, 2011 at 7:46 am



Heather I. February 3, 2011 at 7:46 am

Haha, I totally did that same thing of eating all around the edges of a batch of brownies last week! It all equals about one serving total, right? These blondies look so gooey and delicious, I need to whip these up pronto.


Courtney Blake February 3, 2011 at 7:47 am

Jenna! Your other blondies literally made friends for me when I handed them out the first few weeks of law school. I can’t wait to try these… who knows how popular I’ll be after handing these out! haha.


jenna February 3, 2011 at 8:02 am

hahahaha my goal is to make you the most popular student everrrr! πŸ˜‰


Mara @ What's For Dinner? February 3, 2011 at 7:49 am

Heath bar anything makes me happy. Remind me to send you my grandma’s recipe for Heath bar Mandelbred (like Jewish biscotti). They’re unreal!


jenna February 3, 2011 at 8:02 am

mmm sounds delicious—I’ve tried Mandelbred before and love it!


Heather (Heather's Dish) February 3, 2011 at 7:56 am

please send some to Colorado immediately πŸ™‚


steph February 3, 2011 at 3:50 pm

Yes, I second this!!


Brittney February 3, 2011 at 7:57 am

Oooooh, I HAVE to make these for my husband! He looooooooooves Heath Bars! Thank you for posting this!!


mary (what's cookin' with mary) February 3, 2011 at 8:05 am

Absolutely SINFUL πŸ˜€


Camille February 3, 2011 at 8:06 am

Oh man, you never cease to amaze me! I almost bought Heath Bar bits for a recipe the other day, but then I realized that I was going to end up eating the entire bag, so I refrained πŸ™‚


Cookin' Canuck February 3, 2011 at 8:17 am

Heath Bars are, hands down, my favorite kind of chocolate bar. These blondies are definitely going to be made in my kitchen!


Lu @ Done Dieting February 3, 2011 at 8:21 am

I have been avoiding this awkward conversation because I’m shy (or not so much), but… You. Are. My. Hero!


jenna February 3, 2011 at 8:22 am

not awkward at all!!


Jess February 3, 2011 at 8:27 am

i’m glad you restrained yourself and left out the chocolate. i need more non-chocolate desserts in my life:D


Kelly February 3, 2011 at 8:30 am

Looks wonderful!! Except I don’t like heath bar…I know. I know.


jenna February 3, 2011 at 8:33 am

just add walnuts and skip out on the toffee! Or add white chocolate or regular chocolate instead. You’ll love ’em πŸ™‚


grace b February 3, 2011 at 8:47 am

Heath bar is my favorite candy bar.

When I lived at the beach I used to walk 2 miles roundtrip for a heath bar.

So yea, love those suckers.



Kristin R. February 3, 2011 at 9:42 am

I thought this said “Health Bar Blondies”. Then I scrolled down, saw the HEATH package and was all “Whaaaaa?” Totally confused for a second. These look delicious and much better than what a “Health Blondie” would taste like πŸ™‚ Can’t wait to make them!


Lauren Z. February 3, 2011 at 9:46 am

These look delicious Jenna! I was wondering, will you still from time to time post the step by step pictures and instructions as you have in the past? I think it is SO helpful to see how the recipe forms along the way and to see what it should look like at each stage of the process. Then I know if I’m on the right track to making the dish as heavenly as yours always looks! πŸ™‚


jenna February 3, 2011 at 9:53 am

absolutely! I actually have a pretty special one planned for next week!


Michelle February 3, 2011 at 9:50 am

I got really excited at first… I thought they were HEALTH bar blondies. Damn.


Lindsey February 3, 2011 at 9:57 am

That’s it. I’m making these NOW! One, because I already have the ingredients in my pantry (that never happens to me). Two, because I’m on my period and it’s the perfect excuse to bake/eat something sweet. THANKS!


Maria February 3, 2011 at 9:59 am

I can’t say no to toffee! It is my favorite. Can’t wait to make these and eat the entire batch:)


Casey February 3, 2011 at 9:59 am

Hey Jenna! These look delicious! Question: how can I keep them fresh for a few days? Whenever I make cookies, even in Tupperware they’re hard after like a day…I’d kinda like to make these for the Superbowl but I could also use some for an event I have tonight…so if I made them tonight would they still taste fresh by Sunday at all?



jenna February 3, 2011 at 10:14 am

Make them today, stick them in the freezer (after you slice them–freeze in plastic bags) and then take them out of the freezer on Sunday morning! Good as new!


Lauren February 3, 2011 at 10:03 am

Man oh man. My Superbowl menu is quickly expanding thanks to you. Although I must say, I’m surprised you didn’t add any chocolate?! πŸ™‚


Erin February 3, 2011 at 10:30 am

OMG! I bought some of those toffee bits a month ago when I saw them at a grocery store I never frequent. There were no plans for them, but they looked so fun and irresistable. Since then they have just been sitting in my “mix-ins” basket (which contains approximately 30 bags of chips, bars of chocolates and bits of other things… not including nuts or dried fruits, which have a separate basket all their own… I think I may have a problem ;-)).

I will DEFINITELY be making these for my Super Bowl party. Thank you so much for the inspiration!!!


Lisa @ Sweet as Sugar Cookies February 3, 2011 at 10:33 am

Those look so gooey and incredibly caramelly delicious. Sounds like a real winner to me. I’d like to invite you to stop by this weekend and link these yummy bars up to Sweets for a Saturday #3.


Maren February 3, 2011 at 10:52 am

The only time I’ve tried to make bondies the recipe didn’t work out. So saddening. It’s put me off blondies for life (so far). The brown butter and heath do sound oh so tempting though. Thanks.


Kristy February 3, 2011 at 10:57 am

I read…HEALTH bar instead of Heath bar, looked at the picture and thought, no way is that healthy…this girl has gone crazy!! πŸ™‚


Nicole February 3, 2011 at 11:21 am

Hi Jenna, these look fabulous. Quick question – do you have the let the butter cool before mixing the other ingredients into it?


jenna February 3, 2011 at 11:41 am

You don’t have to!


French Heart February 3, 2011 at 11:38 am

Am also dishwasher/garbage disposal free…because even minor architecturally charming details can trump major modern conveniences for me. I spy Blondie Valentine’s Day gift-making session in my near future. Thanks!


Averie (LoveVeggiesAndYoga) February 3, 2011 at 12:09 pm

I want these!!!! I love love Heath bars! It’s one of my fave things ever! As a kid….I used to eat Heath bar DQ Blizzards like crazy!

perfectly chewy and rich, and absolutely stuffed with delicious toffee bits and walnuts = the way I want my baked goods!

Congrats on the pending move! πŸ™‚


Helena February 3, 2011 at 12:38 pm

I just love eating brownie/blondie/bar edges, they’re definitely the best part!


Ashley @ perfectleypeared February 3, 2011 at 12:47 pm

mmhh these look so moist! I’m definitely making these for valentine’s day! the boy loves them.


sonia February 3, 2011 at 1:27 pm

If you let me lick the bowls, spoons and spatulas I will be your dishwasher and garbage disposal πŸ™‚

Another yummy looking treat! Looking forward to making these.


Amanda @ Cakes and Ale February 3, 2011 at 1:35 pm

What if I used something instead of the Heath bar… like butterscotch chips? Would that work, do you think?
Not that I’ve got anything against a Heath bar. In fact, I think they’re pretty awesome.
It’s just this buterscotch “thing” I’ve had lately… I want it in everything!


jenna February 3, 2011 at 1:38 pm

you can! That would be delicious.


Laurab @FoodSnobSTL February 3, 2011 at 1:40 pm

I totally read this wrong and thought it said HEALTH bolondies. I was having a hard time figuring out what was healthy about them, but I was willing to roll with it.


Chicago Cuisine Critique February 3, 2011 at 1:53 pm

Heath bars are amazing! You may have inspired me to make a little super bowl treat including some heath bits. Yum!


Chelsea @ One Healthy Munchkin February 3, 2011 at 3:16 pm

You had me at the words “ooey gooey”. πŸ˜‰ Although I have no idea what Heath Bars are… I don’t think we get them in Canada.


jenna February 3, 2011 at 4:12 pm

it’s just English toffee! I’m sure you guys have something comparable.


Lisa (Dishes of Mrs. Fish) February 3, 2011 at 3:27 pm

I’ve grown to LOVE Heath bars lately.
So I would like these right now! πŸ™‚


Nancy February 3, 2011 at 5:21 pm

My oh my your blog has changed ( I just read your first post)! Do you still weight the same ( I know this is a personal question) and eat the same amount of calories as you did back then? How did you make such a transition and what caused this?

Love you and your blog no matter which way you decide to eat- salads and heath bars and all! πŸ™‚


jenna February 3, 2011 at 7:35 pm

thank you for reading! Really though, it’s pretty simple: I just changed my mind about what I wanted to do and write about! Nutrition and exercise used to really interest me in my teens and early 20’s and I just feel like over the past year or so I’ve really grown up and discovered “my voice” and what is I LOVE, which is writing about FOOD and developing new recipes to share with all of y’all! πŸ™‚


Sarah K. @ The Pajama Chef February 3, 2011 at 6:32 pm

lovely! i can’t wait to try these!


Samantha Ullrich February 3, 2011 at 6:33 pm

I just always have a bag of health bars in my house (thanks to my obsessed mother)…. I think I might just have to snag the bag and make these!! Plus, everyone knows blondies have more fun πŸ˜‰


Vasu February 3, 2011 at 8:32 pm

Yum yum! Going to go buy Heath bars in bulk so I can make this at anytime.


Hannah @ Hannah Lives February 4, 2011 at 1:27 am

I currently have 1 lb of butter in my fridge and I am desperately trying to narrow down my list of recipes to make so that I do not have to go out and buy more. This has just shot to the top of my list. I blame you for my jeans not fitting. But don’t feel too bad, it’s worth it!

p.s. Congrats on the move! I remember the big move to Cali, crashing at Adam’s, and then the move to the apartment, and now a house! So excited for you!


Megan February 4, 2011 at 7:09 am

I have a bag of those chocolate covered toffee pieces an they have been begging to be turned into some fabulous treat. I think I just found my recipe!


Robin G. February 4, 2011 at 9:40 am

I just discovered your website and I just want to say that I love it. Making these blondies for an all girl Twilight sleepover at my friend’s house in New Port Richey tomorrow night. I know it sounds silly but we girls need any excuse to get together. I just graduated from college so I’m still trying to find myself in the world but your blog has taught me a lot about life and what’s important. I started yoga after many months of doing it once a week or once every two weeks. Keep up the good work.


Michelle February 4, 2011 at 10:39 am

Smitten Kitchen is my food porn. I love her site!


Kristin February 5, 2011 at 4:28 pm

Made these tonight with walnuts instead of almonds. So so good!


Mariah February 6, 2011 at 8:55 am

Made these for the boy and he looved them. Thanks for the recipes Jenna!


Kim February 6, 2011 at 5:13 pm

At first glance, I read “Health Bar Blondies” and thought this should be interesting. I loveeeeee blondies so much more than regular brownies – can’t wait to try this recipe!!! Thank you for sharing!


Alison February 21, 2011 at 7:30 pm

Thanks for this recipe Jenna! It was super easy. The only thing that took any effort was browning the butter and that isn’t hard. I used about 1/2 cup mini-chocolate chips instead of heath since I love chocolate and didn’t have any toffee. It’s the best blondie I’ve had in a long time. My husband raved over it – since I mostly bake healthy vegan recipes – he loves real butter :-).


Brittnee August 11, 2011 at 12:47 pm

Hey! I made these tuesday night and then, expecting to have some the next day, I walked into the kitchen to find no blondies–not even their container they were baked and stored in! AH! I didn’t eat the container, but I’m thinking someone probably like it cleaned then decided to wash the evidence away..


Mark Cunnington September 23, 2011 at 11:06 am

I really liked these Heath bar blondies and I was hoping you could send me another recipe with Heath bars incorporated in them. thanks! πŸ™‚


jenny October 18, 2011 at 9:32 am

made these last night. heaven on earth. thanks for another winner, jenna!


Hannah December 27, 2012 at 10:31 am

These blondies are melt in your mouth delicious! I made these for a friend’s party earlier this year, and they were a hit, so I figured I’d make a pan each for my family’s Christmas celebration and my boyfriend’s family’s Christmas.
They were a favorite among most- 1 pan destroyed at one family’s house and the second almost destroyed at the other. My grandmother (a Cajun food connoisseur) said they were the best dessert she had! Thanks, Jenna!


Michaela January 18, 2013 at 5:35 pm

funniest thing ever: I read “Health Bar Blondies” and was utterly confused when reading the post πŸ˜€
still looks nice!


Sumayyah March 24, 2013 at 4:58 pm

I really wanted these to turn out! Unfortunately when I added the sugar to the browned butter it turned into a sugary crumbly consistency and it only turned creamy once I added the egg. I baked it for the specified time and let it cool. It was then that I realized it cooled into a rock solid slab! what could’ve happened? Any input? I’d really love to try it again with better results obviously.


Kate May 17, 2013 at 4:55 am

How many blondies does this make?
