Our Reese’s Brownies are a dream come true for peanut butter lovers! Made with a layer of fudgy brownies (homemade or box mix, you choose!), thick peanut butter frosting (the actual best), my mom’s famous fudge frosting (get excited), and Reese’s peanut butter cups!

Buckle up, we’re making brownies.

Unapologetically Thick, Rich, and Over The Top
Are these, perhaps, too much?
I mean, the thick fudgy brownie base. The insanely creamy peanut butter frosting. The glossy chocolate frosting of my childhood. The gratuitous sprinkling of Reese’s cups.
I can see why you’re wondering if these are too much, I really can.
But no. They are exactly the right amount of chocolate peanut butter love that we need in our lives. Like, exactly the right amount.
We like to start these off with our homemade brownies when we have the time, but I won’t lie – I’ve definitely made these with a box mix. It’s fine. I get it. Live your life.
The next bake sale that you’re roped into? These.
The next family gathering where you’re asked to bring dessert? These.
The next Tuesday evening snack attack? Yeah. These.
Ingredient Notes:

Brownies – Use either our Nutella Brownies or homemade brownies. Either will work great, and of course a box mix works in a pinch!
Reese’s – We like the Reese’s Minis, mostly because they aren’t individually wrapped and I’m a fan of not unwrapping a million little candies.
Peanut Butter Frosting – You’ll need creamy peanut butter, powdered sugar, heavy whipping cream, and softened butter.
Chocolate Frosting – This is my mama’s recipe! It’s made with chocolate chips, sugar, butter, and milk and turns out glossy and fudgy.
Step by Step:
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!
If you enjoyed these brownies and other dessert recipes with Reese’s, I would highly recommend checking out this air fried Reese’s recipe!
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!

Heck yes! This is my kind of brownie. Although dessert island scenario in hand i’d take a jar of nutella. My sister would have no hesitation in pushing me out of the way for a jar of peanut butter though – can’t wait to make these for her now!

Nichole @TheSaltyMarshmallow says
Oh man! This is one of those desserts I actually imagine sinking my teeth into – so fudgy!!! 🙂
Andi says
Just a note: I frequently make your nutella brownies using peanut butter instead of nutella. This post just upped my game considerably.
Karly says
Woah. Can you actually taste the peanut butter when you add it to the batter like that? I must try it!!
Andi says
Not really. It’s just honestly hard for me to eat them with Nutella. They’re SO RICH! I did it the first time because my aunt is allergic to hazelnut, and they were a hit so I figured why not. 😉
Karly says
Oh! Well, in that case, if you really can’t taste the PB, you could leave it out entirely without making any other swaps. The brownies bake up the same and you save some calories. 🙂 I’m still trying it with peanut butter though. haha!

Love, love, love these Karly! Decadent and indulgent for sure!
