Our Chocolate Peanut Butter Brownies are a dream come true for Reese’s lovers! Made with a layer of fudgy brownies, thick peanut butter frosting, my mom’s famous fudge frosting, and Reese’s candy!
We have a major thing for chocolate and peanut butter in our house and Reese’s are one food we will all fight over.
(Quick – what’s the best Reese’s holiday shape? There’s only one right answer and it will tell me all I need to know about you!)
These Chocolate Peanut Butter Brownies are for serious chocolate peanut butter lovers only!
We start with our homemade brownies here, but you could use a box of brownie mix, if preferred. Our homemade brownies are seriously perfect, nice and thick, and the perfect amount of fudgy!
Next, these get topped with a thick layer of rich, thick peanut butter frosting.
Then my mama’s chocolate frosting gets poured over the top.
And finally – the mini Reese’s cups.
I told you this was chocolate peanut butter overload!

Brownies – Use either our Nutella Brownies or homemade brownies. Both are perfect!
Reese’s – You’ll top these chocolate peanut butter brownies with some bite-sized Reese’s Minis for ultimate peanut butter and chocolate flavor!
Peanut Butter Frosting – The rich and creamy peanut butter frosting layer for these loaded brownies is prepared with peanut butter, powdered sugar, heavy whipping cream, and softened butter.
Chocolate Frosting – The top layer for these loaded Reese’s brownies is a simple homemade frosting that is thin and pourable and will set perfectly. It’s my mama’s recipe! It’s made with chocolate chips, sugar, butter, and milk.

“Wow! These look amazing! Brownies, peanut butter, PB cups! I think the oven is calling, because of course I have all of the ingredients! Thanks for the recipe!” – Laura
How to Make Brownies:
Brownies: First up, you need brownies! This recipe is for modifying already baked brownies to turn them into loaded Reese’s brownies! Start with a 9×13 pan of baked and cooled brownies.
Peanut Butter Frosting: To prepare the outrageously thick and creamy peanut butter frosting layer for these loaded brownies use a stand mixer to beat together the butter, peanut butter, powdered sugar, and heavy whipping cream. You can add more cream if you feel like it needs to be thinned out! We like it thick, to mimic the filling in a peanut butter cup. Spread that over the brownies.
Chocolate Frosting: My mama’s famous homemade chocolate frosting is a thin, pourable frosting that sets up into fudgy perfection. Add some sugar, butter, and milk to a saucepan and boil for exactly 1 minute. Remove from heat, then stir in the chocolate chips until they’ve fully melted into a smooth frosting! Immediately pour that over the peanut butter frosting and let it cool for 5 minutes.
Reese’s: When the chocolate frosting layer has cooled off for a few minutes you can start topping the brownies with the Reese’s Minis! They should sink well enough into the still warm brownies and frosting.
Finally, let these loaded Reese’s brownies cool for about 30 minutes before enjoying! Good luck keeping any willpower around these guys. You’ll be tempted to hoover the whole pan right into your face!

Variations:
Start with a box mix of brownies. Just be sure to use a box meant for a 9×13 pan and make the ‘cakey’ version of brownies rather than the ‘fudgy’ version. (Usually has an extra egg.) This will help the brownie base hold up to all that frosting on top.
Swap the mini Reese’s for Reese’s Pieces to add a little crunch!
FAQs:
You can keep these loaded Reese’s brownies in an airtight container for up to 3 to 5 days.
Yes! If you’re freezing the cut individual brownies, place them in a freezer-safe container in layers separated with wax or parchment paper. If freezing the entire slab of uncut brownies, you’ll want to wrap it in plastic and then aluminum foil.

I love this recipe. I made 2 boxes of brownie mix and baked it in a 10×15 pan. The recipe for the frosting and the fudge topping was the perfect amount for my large pan. I was afraid they would be too rich but they really weren’t. So good! Definitely making these again!
Karen says
These brownies are the best. I did use box brownie mix , they came out perfect. Thanks for sharing this recipe.
Debra L Henson says
I may have to try without the Nutella. I am diabetic and my daughter who loves Nutella, just thew out a jar due to sugar content, guess she had not noticed before. But otherwise will be delicious
Karly says
Hi Debra! This recipe works fine without the Nutella, but there is still a whole boatload of sugar in them.
Julie Pharr says
I could only get 2 cups of confectioners sugar mixed in with the peanut butter. 4 cups seems like a lot of sugar for 1 c of peanut butter?
Andi says
The recipe has you adding the powdered sugar and heavy cream at the same time. Did you alternate?
Karly says
Did you also mix in the butter and heavy cream? It’s a pretty common ration of fat to sugar so should be fine to mix in if you’re using a mixer. This one won’t work well by hand.
Sara says
Am I crazy or is the amount of milk for the chocolate frosting missing from the recipe? Any help would be greatly appreciated. Thanks!
Karly says
You’re not crazy! I’m in the process of updating old recipe cards and this one didn’t seem to transfer properly. Updated now – you’ll need 6 tablespoons of milk. Enjoy!!

No idea. You’re welcome to plug the recipe into an online nutrition calculator if you think you can handle the info though. Personally, I’d rather not know. 😉
