chocolate chip peanut butter swirl blondies

by jenna on May 31, 2011

We had fourteen people over for dinner last night and I mastered the art of multitasking by proving I can stuff jalapenos, grill portobello mushrooms, make mojitos, and make faces at Ashley’s sweet baby girl all the same time.

I had beads of sweat running down my eleven dollar clearance Old Navy dress.

But can we just talk about these blondies for a moment? I promise I’ll get back to the parties and the mojitos that changed my life in a few minutes. But for a moment we need to chat about these blondies. And the fact that they totally unhealthy yet taste really, really, really good? Oh yeah.

I made them a few days ago and have sorta been thinking about them ever since.

They’re that good.

Think glorified soft chocolate chip cookie with a rich peanut butter swirl running through it. It doesn’t really fit with our new “healthy eating plan” but you know what I say to that?

More peanut butter.

Blondies > cookies

More chew and density. You feel me?

Chocolate Chip Peanut Butter Swirl Blondies

makes about 16 blondies

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

1/3 cup creamy peanut butter

1/2 cup chocolate chips

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 butterβ€”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, then add peanut butter and gently mix so the batter is just swirled.

Fold in the chocolate chips. pread 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 couldn’t agree more πŸ™‚

Jil @ Big City, Lil Kitchen May 31, 2011 at 7:32 am

This sounds increeeeddible


kaila @ healthy helper! May 31, 2011 at 8:36 am

Andie @ CanYouStayForDinner May 31, 2011 at 7:33 am

I’m in love πŸ™‚


Lauren at Keep It Sweet May 31, 2011 at 7:34 am

You read my mind because I was JUST thinking about peanut butter blondies!


Jenny May 31, 2011 at 7:34 am

These look great! Easy and sweet, and I know anything with browned butter has to be the best!


Chloe (South Beach Girl) May 31, 2011 at 7:35 am

Those look wonderful – I’m a sucker for anything that involves peanut butter!


Jemma @ Celery and Cupcakes May 31, 2011 at 7:36 am

PB and chocolate are a match made in heaven!


Liv @ The Salty n' Sweet May 31, 2011 at 7:36 am

You can never create too many peanut butter + chocolate recipes! Loving the whole stick of butter πŸ˜‰


Angela @ Eat Spin Run Repeat May 31, 2011 at 7:36 am

Ohhh my. These sound amazing! Blondies and PB = pretty much perfect!


Courtney @ The Granola Chronicles May 31, 2011 at 7:36 am

A stick of butter? I’m in! πŸ™‚


Katherine May 31, 2011 at 7:36 am

In the same general baking vicinity, my sister made her go-to basic brownies tonight and they were so good I devoured an entire row before I came to my senses. LOVE the chewy, fudginess of brownies. I think I’ll have to tackle these blondies myself though, because my sis is ser-i-ous when it comes to the purity of her brownies : )


Louise May 31, 2011 at 7:40 am

It’s like you know I’m pregnant. I can’t wait to make these!


Jessica @ How Sweet May 31, 2011 at 7:42 am

The combination of the gods… mmmmm.


Brooke @ bittersweetb May 31, 2011 at 7:42 am

I want one of these right now! Holy peanut butter!


Estela @ Weekly Bite May 31, 2011 at 7:44 am

What a great combo! I love blondies! The PB & Chocolate make it even better πŸ™‚


Faith @ lovelyascharged May 31, 2011 at 7:47 am

Most of my favorite desserts involve some combination of chocolate and peanut butter. Definite yum!


jen @ taste life May 31, 2011 at 7:49 am

I couldn’t even read all the ingredients on the list because I vowed to eat more vegetables and less sweets this week! These are too tempting!


Holly @ The Runny Egg May 31, 2011 at 7:51 am

Blondies are way better than cookies. I totally agree.


d.liff @ yelleBELLYboo May 31, 2011 at 7:51 am

Look delicious!! I haven’t made any brownies or blondies in a long while, it might be time!


Averie (LoveVeggiesandYoga) May 31, 2011 at 7:51 am

It was destiny. I JUST left Kath’s blog where I JUST left a comment about Jif natuarals PB. I won’t link drop the Url, but I just did. WHAT Are the odds?!!! And I come here and see a big jar of Jif Naturals.

The odds are saying that I better be making these, stat.

They look wonderful and I am a huge blondies AND Pb lover. Match made.

And multitasking while entertaining…isn’t it amazing what all goes into a dinner party for a group of folks…right down to the making gaga faces at someone’s baby when all you’re thinking about is omg I am burning the xyz right now! but you keep smiling and hope the Burn Gods have saved your food πŸ™‚


Brooke at Waiting to Rise May 31, 2011 at 7:53 am

Yummy! I think I’ll make it this weekend for my cookout!


Urban Wife May 31, 2011 at 8:04 am

This recipe is truly testing my willpower. Ugh. πŸ™‚


Mellie May 31, 2011 at 8:10 am

I can’t make these, or else i will eat half the pan. πŸ™‚


Cait @ Beyond Bananas May 31, 2011 at 8:23 am

I am totally with you.. I might push it to the 3/4s of the pan.. maybe even the whole thing πŸ˜‰


Baking N Books May 31, 2011 at 10:28 am

Okay, Mellie does 1/2, Cait you do 3/4…let’s face the facts – I WOULD do the full…not sure if that’s a πŸ˜‰ or a :(.


It’s Natural PB – that’s healthy. πŸ™‚


Katie May 31, 2011 at 8:18 am

The last time I browned butter, combined it with sugar, and then mixed in the egg – the egg curdled. Any tips? How long can the browned butter sit out and cool? I don’t think can handle the anticipation of deliciousness dashed to disappointment again. Thanks!


jenna May 31, 2011 at 8:48 am

That’s interesting! I’ve never had that happen. You beat the browned butter with the sugar for a few minutes so it has a chance to cool down before adding the egg, and even when you add the egg, you beat like heck…so it really SHOULDN’T curdle. Instead of letting the butter cool, i would suggest beating more!


Mary @ Bites and Bliss May 31, 2011 at 8:23 am

I’ve been into a “peanut butter swirl” mood ever since making PB swirl banana bread a few weeks ago. These look amazing and so dense. My tastebuds are having a party just looking at them.


britt May 31, 2011 at 8:35 am

so i was considering giving up sweets starting tomorrow but i may have to put that off after seeing these. yummm!


Khushboo May 31, 2011 at 8:42 am

These sound heavenly, perhaps your best recipe yet! The last batch of blondies that I made involved chickpeas and they tasted like ass! I am 120% certain that I don’t run any similar risk with these babies!


jenna May 31, 2011 at 8:47 am

As much as I love me some chickpeas, they don’t belong in blondies!!


VeggieGirl May 31, 2011 at 8:50 am

You know how much I love blondies πŸ™‚


Amy May 31, 2011 at 8:54 am

oh my.


Krystina (Organically Me) May 31, 2011 at 9:02 am

This is like a thick, chewy chocolate chip cookie. I’ll take six.


Kiran @ May 31, 2011 at 9:06 am

A scoop or two of ice cream with these babies, holy yum!


chelsey @ clean eating chelsey May 31, 2011 at 9:25 am

Who says blondies can’t be healthy? πŸ™‚


Sarah May 31, 2011 at 9:30 am

These look amazing! I’m in love with JIF natural peanut butter too so I think these are right up my alley.


Kelli H (Made in Sonoma) May 31, 2011 at 9:40 am

These look amazing!

p.s. I don’t know how into beer you are but there’s a beerfest going on on Saturday. If you don’t have plans, you should check it out!


Shannon Blogs May 31, 2011 at 9:41 am

this has everything that I would ever want in a dessert…..they look soooo good!


Ruth May 31, 2011 at 9:54 am

These looksamazing, Jenna. πŸ™‚


Heather May 31, 2011 at 10:06 am

I know I could use something peanut buttery right about now!


Jen May 31, 2011 at 10:43 am

As much as I love chocolate, blondies always seem to intrigue me more than brownies do. And peanut butter ALWAYS gets my attention. I visit your blog for the food porn, obviously.


Justeen @ Blissful Baking May 31, 2011 at 10:46 am

Mmm I am in a peanut butter and chocolate mood right now, and I could just devour the whole pan!! These blondies look spectacular. I made a batch of blondies last week with peanut butter and chocolate… and chickpeas. They were delicious, but you can’t beat the taste of butterrr!!


Katrina May 31, 2011 at 11:11 am

Ohhhh I just love blondies! Beautiful.


Heidi @ Food Doodles May 31, 2011 at 11:27 am

Mmmm, that peanut butter sounds amazing. PB+Blondies=Heaven! πŸ˜€


amyt @ Chicken Nugget Momma May 31, 2011 at 11:40 am

HOLY yum!! peanut butter + chocolate… cannot go wrong (most times anyway!)


Daniella @ Runner at Heart May 31, 2011 at 12:51 pm

These look good I wish I liked to bake so I could make some of these yummy treats but baking just is not my thing.


Meghan @ StruggleMuffins May 31, 2011 at 12:52 pm

No bad can come from the collision of two beautiful, beautiful worlds: peanut butter and chocolate. I almost cringe at the thought of having given PB and chocolate ‘world’ status, but ultimately, they’re just.that.big.


jenna k May 31, 2011 at 1:15 pm

yummy! i may try these with almond butter because i just picked up a jar today.


Happy When Not Hungry May 31, 2011 at 3:32 pm

Wow these blondies look amazing!!! Love anything with brown sugar and peanut butter. Yum!


amy walters, aDESIGNdock May 31, 2011 at 8:03 pm

These look a-mazing! Jenna, you’re the best πŸ˜‰


Stephanie Murphy June 1, 2011 at 6:53 am

There is never a good enough excuse to turn down any type of chocolate/peanut butter combo. πŸ˜‰

I plan to host a dinner party in the near future, and you’re hosting talents are certainly an inspiration. I don’t have much experience in multi-tasking for preparing multiple dishes in the fact that I’m a teenager, and hosting a dinner party is not something that a teen would typically choose to do. Although my friends may not be interested in sitting around drinking virgin sangria and discussing current events on a Saturday night, I’m sure my grandparents will be glad to join me!


Danielle @ InDeesKitchen June 1, 2011 at 9:06 am

Yummmm! Those look delicious!


Katie June 3, 2011 at 5:41 am

I made these and my boyfriend declared them “one of the top 3 baked goods he has ever eaten”!!!! They were great! Thanks for the recipe!


Heidi @ The Balance Project June 16, 2011 at 1:24 pm

Made these last night for my family. One word … AMAZING.

There is only 1 left 24 hours later and I am about to go eat it!

Thanks!! : )


Lorin June 16, 2011 at 1:34 pm

I made them today for a bonfire, they just came out of the oven and they smell so good! Definitely going to have to “test” before I give it to my friends πŸ˜› Chocolate, peanut butter, and sugar, can’t go wrong there.


Lorin June 16, 2011 at 5:01 pm

I just tried it, they’re really good, but they don’t have much of a peanut butter taste. I “tested” two though, so they were delish πŸ™‚


Jessica @ Bake a Little July 19, 2011 at 1:02 pm

These look amazing! I am a huge fan of Snickerdoodles, especially snickerdoodle blondies. I made a Chocolate Chip Snickerdoodle Recipe here…
but I think adding the peanut butter takes it to a whole new level! Love it!


LauraB September 12, 2011 at 11:00 am

Delish. Delish. Delish! Made them. Love them. End of story and beginning of bigger pants size. Taste report: like a moist and chewy peanut butter cookie that made friends with a brownie and had chocolate chip babies.


Lula October 5, 2012 at 12:23 pm

I just made a gluten-free, dairy-free rendition of these (allergies) and they came out GREAT! Thanks for providing this recipe!
