Triple Layer Mint S’more Brownies

by jenna on December 15, 2010

I’ve made some bad decisions in my life.

Cutting my own bangs in fourth grade? bad decision.

Wearing a baby tee that said groovy past 1998? bad decision.

Hopping into a industrial sized steam kettle after a company Christmas party? very bad decision.

However, I’ve also made some good decisions. And I like to think that my best decision yet has been to bake these triple layer mint s’more brownies.

Imagine a thick, fudgy brownie with a chewy mint creme layer and a roasted marshmallow top.

It’s kinda ridiculous….as in probably the best brownie I’ve ever tasted in my entire life. Also, for the record—Adam says it’s the best thing I’ve ever baked.

And that there is saying something.

When I created these, I had s’mores on my mind. Then I got to thinking about brownies and how I don’t have a single brownie recipe on the blog.

There’s something a lot wrong with that.

And then, I start thinking about mint because I have a random bag of peppermint patties in my secret drawer. I’ll occasionally eat one or two when I’m bored and out of nutella.

So yeah….all that led to these triple layer mint s’more brownies and they’re really good. I highly recommend them for any and every chocolate craving.  And despite the whole “triple layer” bit, they’re incredibly simple to make.

Perfect, I think, cut into small brownie bites and arranged on Santa’s cookie plate. If Santa was a good boy this year, that is.

And the marshmallows on top?

Necessary definitely.

All you do is sprinkle them on after the brownies are finished baking and then stick under the broiler for a few minutes.

The hardest part is waiting for these suckers to cool.

Baking these is a really good decision.

Triple Layer Mint S’more Brownies

makes about 16

adapted from Martha Stewart

1/2 cup all purpose flour

1 cup sugar

1/2 tsp salt

1/4 cup cocoa

4 oz butter

8 oz semi-sweet chocolate chips

3 eggs

1 tsp vanilla extract

2 cups mini marshmallows

25 mini peppermint patties

Preheat the oven to 350.

Melt the chocolate and butter together over very low heat on the stove. Remove and whisk in the eggs. Add the flour, cocoa, salt and sugar and mix well to combine.

Line a nine by thirteen inch baking pan with tin foil. Butter the foil (really butter it!) and then pour half of the brownie batter in the pan. Arrange peppermint patties over top and then spread the remaining batter over top, smoothing it out with a palate knife.

Bake for 45 minutes and then sprinkle marshmallows over the top. Broil for two to five more minutes, until the marshmallows are lightly browned and gooey.

Let cool for AT LEAST an HOUR before attempting to cut. And when you do cut, spray your knife with cooking spray or else the marshmallows will stick to it. Cutting these is tricky, yes, but the end result is very, very worth it. I used a combination of a knife and a scissors to cut. Don’t give up!

wow. after experimenting with your flourless chocolate cake (and it turning out amaaaazing btw), this will definitely be my next endeavor. You rock.


Heather (Heather's Dish) December 15, 2010 at 7:35 am

oh my gosh. these are INSANE! stretchy pants, here i come!


bakingnbooks December 15, 2010 at 8:13 am

I agree. Jenna, you are Trouble with a capital T. I think I’m going to have to stop coming here…



Jessica @ How Sweet It Is December 15, 2010 at 7:36 am

Okay, s’mores is my MOST favorite flavor combo, but then you go and add mint to the mix? I think I just died and went to heaven. See you there!


Jessica @ How Sweet It Is December 15, 2010 at 9:52 am

Came back for more and stumbled these. The first picture is just insane. I’m hangry.


Tracey @ I'm Not Superhuman December 15, 2010 at 7:39 am

I’ve made brownies with a mint center, but this is just unreal. Melted marshmallow top? OH WOW.


Michele @ Healthy Cultivations December 15, 2010 at 7:39 am

Okay, THESE look truly fantastic!!

I have to ask you — is your freezer packed full of the goodies you make every day? There’s no way you’re eating all of these.


jenna December 15, 2010 at 10:29 am

everyone’s freezer is packed with the goodies I make. 😉 I do try everything though and bake in very small batches!


Danielle @ InDeesKitchen December 15, 2010 at 10:30 am

I wonder too. And if so, Jenna – can I come live in said freezer?


jenna December 15, 2010 at 10:31 am

yes…the freezer is rent-free.


Alina @ Duty Free Foodie December 15, 2010 at 7:40 am

That looks freaking awesome. I love peppermint patties (and their derivatives).


Maria December 15, 2010 at 7:40 am

I know these are going to be dangerous, in a very good way:)


Kati @ Living Well December 15, 2010 at 7:41 am

YUM. You’re so creative!


Laura @ Backstage Pass December 15, 2010 at 7:46 am

These sound delightful!


mindy @ just a one girl revolution. December 15, 2010 at 7:46 am

I am definitely making those. Like, tonight.


Krystina (Basil & Wine) December 15, 2010 at 7:47 am

I feel my pants tightening already, but I must have brownies. Unfortunately I used up all my flour for cookies today…guess that means yet another grocery trip.


MaryK. December 15, 2010 at 7:47 am

I dont know why I read this while sitting at work cause then all I can do is sit here and dream about making these later…. plus I’m sure drool isnt good for my keyboard. :)

(Of course I truly know why I read this at work, cause I’m anxiously awaiting your newest recipe and cant possibly wait til I get home to check it. I’ll be stopping at the grocery store on the way home now to get some peppermint patties!)


Amalfi Girl (EatRunHaveFun.blogspot) December 15, 2010 at 7:48 am

Yowza, those look scrumptious.


Bethany @ More Fruit Please December 15, 2010 at 7:49 am

Ah-mazing! It looks like you got the marshmallow top just the shade of golden!


Mary (Sisters Running the Kitchen) December 15, 2010 at 7:50 am

Oh. My. God. I am speechless. Must make ASAP!


Alison (Fueling for Fitness) December 15, 2010 at 7:53 am

Mmmmmm, thank you kindly. :)

The first chance I get, I am SO making these!


Therese December 15, 2010 at 7:54 am

Oh, Jenna! You’ve outdone yourself! You’re so good to us! YUM!!!!!!


AllieNic @ Frisky Lemon December 15, 2010 at 7:56 am

I too have a random bag of peppermint patties for special occasions/chocolate emergencies….mayhaps I will use them tonight! What a great/delicious brownie creation! Thanks for sharing…


Shareece December 15, 2010 at 8:00 am

Oh my goodness. I can’t wait to try and make these!


The Blue-Eyed Bakers December 15, 2010 at 8:01 am

Umm…we’re making these tonight. Lucky for us we always have peppermint patties on hand (major addiction issue). Seriously – the best thing you’ve ever baked?!! How can we not!?!


Steph@stephsbitebybite December 15, 2010 at 8:04 am

I feel like I’m being tortured! These look so scrumptious!


Blog is the New Black December 15, 2010 at 8:12 am

OMG… these sound wonderful! You amaze me.


RhodeyGirl December 15, 2010 at 8:13 am

Peppermint patties! I forgot all about them. I have a secret stash of goodies too, but I keep mine in the freezer. It’s currently (gasp) EMPTY since I did that no sweets thing a couple of months ago!

I’d like to see the pic of you in the tea kettle.


jenna December 15, 2010 at 10:29 am

there may or may not be a photo lurking somewhere on this blog. I didn’t link to it for a reason! 😉


Janna December 15, 2010 at 8:15 am


I just made brownies yesterday, but I think I now have to make more.


jenna December 15, 2010 at 10:28 am

you never can have too many brownies. obviously.


Jen H December 15, 2010 at 8:15 am

Wow, these look amazing. Do you think these would still be good a day or 2 after baking (if they last that long!)? Or do they need to be eaten same day?


jenna December 15, 2010 at 10:28 am

I tested that fact this morning when I ate half of one before breakfast…it was even more amazing! Just store in tupperware and you’ll be good to go!

Reply December 15, 2010 at 8:16 am

I have peppermint patties at home and I will be making these!! WAHOO!!


Allison @ Food For Healing December 15, 2010 at 8:20 am

Those look so delicious, minus the peppermint patties, i’m not a fan of those. but i do LOVE marshmallows! i’ve been craving some lately for some reason, and now you made it worse! lol


Maria (The Fitted Apron December 15, 2010 at 8:22 am

Holy Cow! Those look sinful! Must make the next time I need a chocolate fix.


Cassidy @ takingmyplace December 15, 2010 at 8:28 am

Ah! Those look amazing! Your blog is one of the many reasons that I am such a bad vegan (maybe that is a bad decision, haha)… I cave to butter too much! I think I have to make these! I’m the worst vegan ever!


notyet100 December 15, 2010 at 8:29 am

wow,..thy look so yum..


Averie (LoveVeggiesandYoga) December 15, 2010 at 8:41 am

Holy amazing!! I just posted a marshmallow recipe the other day, with chocolate and PB too. I LOVE marshmallow anything. I love love love those lil buggers! Smores are my fave. No wait, brownies are :)

And I love that you smooshed peppermint patties IN your brownies. I do that with reese PB cups in my brownies. Oh this is just a KEEPER of a recipe!!

YUM!! Thank you for sharing!


Liz December 15, 2010 at 8:43 am

Wow… YUM. I approached this post with some trepidation, because I didn’t think that graham crackers and mint would mix. I see you’ve omitted graham crackers and the s’mores part comes in with the marshmallows. Looks FANTASTIC.


Lindsey @ Morningstar Project December 15, 2010 at 8:43 am

As soon as I saw the title of this post, I literally said out loud “Jenna why do you do this to me??” I wanted to look away because I knew I was doomed once I scrolled down. Well I did and these are going to get made, and perhaps eaten all by myself, and then I’ll be happily wearing sweat pants the rest of the holiday season :)


megan @ whatmegansmaking December 15, 2010 at 8:45 am

They look AMAZING! :)


Bethany December 15, 2010 at 8:45 am

Holy moly. Um why did I check your blog while at work? Now I anxiously want to go home and bake these. AHHHHHHHHHHHH. YUMMY.


Liz December 15, 2010 at 8:50 am

Upon second thought, not to be overly critical… graham crackers are an integral part of s’mores. Otherwise, you’ve got a chocolate marshmallow concoction, which is also delicious, but does not taste like s’mores. You might want to rename this (but I can’t think of a clever name.)


Carolyn @ EatWell. LiveWell. BeWell. December 15, 2010 at 8:53 am

These look delicious… I so wish York Peppermint patties (and this recipe) were vegan.

Actually , no. Maybe I don’t. 😉


Erica D (Gratitouille) December 15, 2010 at 8:53 am

Ouch! I think I just got a cavity…

Yum 😛


Kylie @ A Hungry Spoon December 15, 2010 at 9:02 am

These look AMAZING! My sister is a peppermint patty fanatic, so I have no doubt these will be on her list to try (or my baking list for her Christmas cookie plate…)

Thanks for sharing!


Angela (Oh She Glows) December 15, 2010 at 9:08 am

These are all kinds of epic!!!


Lauren at KeepItSweet December 15, 2010 at 9:16 am

love the peppermint patties oozing in the middle!


VeggieGirl December 15, 2010 at 9:18 am

Psst… hey Jenna!!! I’ll trade you a batch of my blondies for a batch of your mint s’more brownies :)


jenna December 15, 2010 at 10:27 am

:) you know how much I adore your blondies!


Lisa December 15, 2010 at 9:19 am

These look heavenly!! I love chocolate and mint together!


Kelly December 15, 2010 at 9:32 am

My husband would love these…although I hate mint. But I have made smores brownies with just putting graham crackers in the middle. They were awesome. You know those girl scout cookies…tag a longs…how good would those be in the middle of brownies??


jenna December 15, 2010 at 10:26 am

yes. yes. yes and YES.


Alex Johnson December 15, 2010 at 9:35 am

I LOVE that as I click on your site to check what I should make for dessert (planning a meal for my boyfriend) I don’t even have to click “Recipe Section”, you must have been reading my mind!
I was thinking of either smores or brownies.
This sounds like a dream. Could I pair it with ice cream?
Oh gosh.


jenna December 15, 2010 at 10:26 am

the real question is, why wouldn’t you pair it with ice cream? 😉


Nora@LiveLifeEatRight December 15, 2010 at 9:40 am

Heaven? This is like all of my favorite foods rolled into one super dish! You are my hero.


Moni'sMeals December 15, 2010 at 9:44 am

Unreal! I have to make these. Killer combo. :)


Amber K December 15, 2010 at 9:48 am

Ok, you and Angela are pretty much the only bloggers who make me need a drool-shield for my keyboard. Seriously, yum.


britt December 15, 2010 at 9:51 am

wow! marshmallows on brownies sounds so delicious!!


Jenna December 15, 2010 at 9:54 am

You read my mind!!! I was searching for a york mint brownie recipe the other day but went with andes instead. now i can try these :)


jenna December 15, 2010 at 10:26 am

these would probably be great with andes!


chelsey @ clean eating chelsey December 15, 2010 at 10:05 am

Those look insane – kind of want me to ditch my corn/gluten intolerant self for a day so I can eat an entire pan.


Danielle @ InDeesKitchen December 15, 2010 at 10:27 am

These look insanely good! Thanks Jenna!!!


Danielle @ InDeesKitchen December 15, 2010 at 10:29 am

These look insanely delicious! Thanks Jenna! :)


Rachel @ Fit Fun and Fabulous December 15, 2010 at 10:34 am

So if I plan to just dive into these with a fork without cutting I don’t need to wait an hour right?!


jenna December 15, 2010 at 10:36 am

Right. But beware of the sticky marshmallows! :)


Dee December 15, 2010 at 10:46 am

A-may-zing! What a genius idea!


jenna December 15, 2010 at 11:18 am

i bet these go perfect with a mug of coffee. or almond milk!


Lizzie December 15, 2010 at 11:19 am

OMG I am making these tonight for my boyfriend to bring to his office party! I will obviously have to try one for quality control purposes…..


Fit Chick in the City December 15, 2010 at 11:31 am

You have outdone yourself!! This sound amazing!


Traci(faithfulfoodiefashionista) December 15, 2010 at 11:47 am

Oh yummy :)


Alicia December 15, 2010 at 11:54 am

These look mind-blowingly good. Thanks for the great recipe!


Clare @ Fitting It All In December 15, 2010 at 1:21 pm

Wow. I think i’d like making these with andies mints instead of peppermint patties too.


MyThy December 17, 2010 at 9:53 am

Clare, did you make them with Andes Mint? How did they turn out? I have the baking Andes mint bits and wanted to try that.


Tamizn December 15, 2010 at 1:46 pm

Oh my god! They look good x x


Emily @ For Sweets Sake December 15, 2010 at 2:43 pm

mint, chocolate and s’mores all in one? I’m in heaven!


Stephanie December 15, 2010 at 2:44 pm

Those look amazing, can’t to try this recipe out! Thanks for sharing Jenna!


Sara December 15, 2010 at 4:28 pm

I love your blog. Like, LOVE. Love-love. :) So glad I stumbled upon it!


alwayslosingbobbypins December 15, 2010 at 5:24 pm

These looks so delish that I made them for the hubs tonight as a surprise. Then this happened:

Will you come make them for us?


jenna December 15, 2010 at 5:26 pm

oh no!!!!!!!!!! My heart.


jenna December 15, 2010 at 5:27 pm

after pondering this for about two minutes, I really feel like you could peel off the burned marshmallow layer and try again without re-making the brownies!


caitie December 15, 2010 at 5:35 pm

hahahahh um well i LOVE burnt marshmallows so send ’em my way!


allison marie December 15, 2010 at 5:28 pm

These looked so delish, I tried to make them for my hubby as a surprise.

This is what happened:

Please come make them for us :)


alwayslosingbobbypins December 15, 2010 at 5:29 pm

hehe sorry to repose twice.

I tried but i burnt it so bad I threw away the pan. The worst part? I’m allergic to flour so I spent 10 bucks on the premade mix :) I’ll try again though, no worries. xoxox


Chelsea @ One Healthy Munchkin December 15, 2010 at 6:01 pm

This makes me want to just ditch real meals and start eating desserts all the time instead. Who needs things like chicken and pasta when you have these!? 😀


jenna December 15, 2010 at 6:34 pm

holy yummmm!


Caroline December 15, 2010 at 7:41 pm

OK I’m glad I’m not the only one who completely burned them! Jenna, did you really broil for five minutes?? My marshmallow was literally ON FIRE after two minutes!


jenna December 16, 2010 at 8:28 am

hmmm I did, but it might be my oven. I would say 2-5 minutes, keeping an eye on them! I’m so sorry!!


Caroline December 16, 2010 at 1:32 pm

haha not your fault, I should have known better than to leave my broiler unattended! I’ve just never broiled marshmallows before. no worries, my second attempt was successful and delicious!


Kaethe Richter December 16, 2010 at 6:49 am

making these today <3


Sarah December 16, 2010 at 12:10 pm

Definitely adding these to my holiday baking tins – yum!

On another note, your White Chicken Chili recipe has become a staple in our house, my husband requests it on an almost weekly basis. So good for our cold Chicago winters.


Jaclyn December 16, 2010 at 2:56 pm

Wow those look dangerous. Delicious, but dangerous.


Stephanie P December 16, 2010 at 7:43 pm

I made these tonight!!! They turned out great, except my peppermint patties exploded during the baking process… haha… did your’s do this? They still taste good but when you cut through the peppermint, it’s not pretty like yours is in the picture…

Anyways, they taste great!! I can’t wait to share them with the boyfriend’s family this weekend :)


Abby December 14, 2012 at 10:17 am

I made these last night and that happened to me too… it also seemed like there wasn’t enough batter for the two layers in the 9 x 13 pan (which meant that 45 min might have been baking them too long) … maybe I’ll try a smaller pan next time.


Kaethe Richter December 17, 2010 at 12:29 pm

they one on my kitchen countertop right now cooling.

resisting. the. urge.


Sara December 18, 2010 at 3:26 pm

2) I just made these.
3) I LOVE YOU, really.
5) Thank you!

😀 I’m going to blog about it tomorrow and link back to ya. You rock! Ps- it helped to slather butter on my knife before cutting. I didn’t have to use scissors, I just kind of peeled the foil away from the bottom and the tore the semi-cut brownies apart with my hands.

Pps- unless I’ve gone mad, you don’t mention when to add the vanilla or cocoa powder, but I added the vanilla to the melted chocolate and the cocoa to the dry ingredients. They are probably the best thing I’ve ever made… and eaten.


Lacey @ Lake Life December 18, 2010 at 3:33 pm

Those look delish!

I too, cut my bangs in 4th grade (while they were wet) AND had a “Groovy” baby tee!


Jen December 18, 2010 at 6:21 pm

OH MY GOD……drinking wine and making these….can’t ask for a better Saturday night!!!!!! These are YUMO!!!!!!!!!!!!!!!!!!!!!!!!!!


Elizabeth December 19, 2010 at 12:16 pm

Am in the middle of making these now. Smells great!!!! Making them for the bf’s mother’s B-day. I’ve been loving the new tone of your blog. One smaaalll thing– Vanilla and salt never made it into the write-up portion of the recipe instructions (I’m one of those people who would want to know). Thanks for sharing with us!


Heather December 20, 2010 at 8:44 pm

Yeah, i noticed that too and neither did the cocoa. And when i made them i realized the baking time was way too long. All of the outsides were burnt and sadly ended up in the garbage :(


jenna December 20, 2010 at 9:20 pm

hmmm I admit I forgot to write when to add the cocoa (it’s fixed), but the baking time was correct and was also correct with about five others who made this. Ovens are different though and maybe you have a super hot one?


Heather December 21, 2010 at 11:21 am

Yeah, the oven has definately seen it’s better days! But not to worry, I shall try again! Hopefully with better results this time :) Thanks!


Stacie December 19, 2010 at 2:35 pm

I made these yesterday and HOLY MOLY what an amazing recipe!! My whole family was drooling over them! You are right though, they are impossibly difficult to cut but soooo worth it! This is a recipe I am adding to my favs! Thanks for sharing!


Ffion December 22, 2010 at 10:44 am

I’v been trying to fight my chocolate craving all day, but these just pushed me over the edge. Only thing is, I want them NOW, and I don’t have the ingredients! Looks like I’m breaking into my secret B&J’s Chocolate Fudge Brownie ice cream stash pronto!


Michelle December 30, 2010 at 1:24 pm


I made these today…the house smelled amazing! I just have a question and maybe you can give me a few tips….
I made these exactly how you wrote in the recipe…but mine came out very dry and not moist yummy brownies. :( Do I need to cook them less? Should I add more of something to make them gooey? Please help! I want to make another batch for tomorrow :)


sarah January 22, 2011 at 4:17 pm

mmmmm i would make these tonight but i’m not home.. TOMORROW IT IS! My co-workers will love me


Maureen January 30, 2011 at 8:36 am

Made these last night for a friend’s birthday. I cooked them for 30 minutes because my oven runs hot. Burnt the marshmallows the first time, scraped them off and tried again. Peppermint patties exploded but hey who cares? They were a hit at the party.
I loved them even though I’m not big on sweets or brownies anymore. My 10 year old self who used to eat jam out of the jar just cried by me writing that.


Beth February 2, 2011 at 9:02 am

I just made these last night – OMG! They are so good!!! I totally forgot (in my excited rush) to put the vanilla and salt in – whoops! And I used Andes Mints instead of peppermint patties. Amazing. I was thinking of giving the rest away to my husband to bring to work, but I think I’ll just have one a day, if I can control myself around them. Thanks for this awesome recipe Jenna!


Caroline February 3, 2011 at 5:08 pm

I’m making these right now, and having a sort of scary mint-melting moment going on? The mint patties have completely melted and are bubbling up through the brownie batter, and the whole thing isn’t really solidifying at all…help!!!


jenna February 3, 2011 at 9:28 pm

Oh my goodness!! Are you sure you added all the ingredients properly and didn’t forget anything ?!


Caroline February 4, 2011 at 6:54 am

oh man, how embarrassing!! I just double-checked this morning and realized that it’s because I was trying to double the recipe but didn’t double anything except for the butter and sugar! duh!


jenna February 4, 2011 at 7:57 am

oh no!!! Don’t worry—I’ve totally done that before!


Caroline February 6, 2011 at 11:54 am

replying to say that I’ve made them *properly* this time, ahaha, and they were a huge hit at my bake sale! thank you!

Ashley H. April 28, 2011 at 4:43 am

I tried these last night because, after reading the recipe, I couldn’t WAIT! I have one word of advice about adding the marshmallows on top. If you’re an idiot like me, DON’T put them in the broiler on high and close the oven door! My marshmallows CAUGHT ON FIRE and I had to scrape the entire top of charcoal black marshmallows off the top and start over! I should have known – high heat + marshmallows = fire, hahah. The 2nd time I did it I made sure to put the broiler on low and keep the door open a crack. Anyway – they were absolutely delicious and I love the addition of the peppermint patties.


Aimee from AL May 17, 2011 at 5:55 am

Made these this weekend and they were a HIT! Thanks so much! Delicious!


sazzy August 31, 2012 at 8:59 am

I just made this and I just pulled it out of the oven. Just realized that I didn’t put vanilla extract in it, because the directions didn’t tell me to. I felt funny.. and realized that part was left out! Oops. Hope it’s still good in an hour! It SMELLS good!
