Why You’ll Love This Recipe
Ever since I made my one bowl fudgy brownie recipe I have been making brownies nonstop – and this time I decided to add every single peanut butter candy in my pantry. We are HUGE peanut butter chocolate lovers in this house – and I knew the combo would be amazing.
Skip the microwave and stand mixer – these are easy to make, one bowl, and are so chocolatey, rich, and fudgy! They’re a favorite of several friends of mine, who make them every chance they get. I’ve heard these proclaimed one of the best desserts you’ll ever try – and I agree!
If you’ve a peanut butter and chocolate lover or you are as obsessed with Reese’s as I am, THESE Ultimate Reese’s Brownies are for you!
Important Ingredients
- Oil – instead of butter these use oil which keeps them nice and rich.
- Eggs – 5 large eggs in one brownie recipe – seems like a lot but that’s where all that fudgy texture comes from.
- Cocoa – I used natural unsweetened cocoa powder but you can use dutch-process cocoa if you want.
- Peanut Butter Candy – clean out your pantry and use a combination of Reese’s Pieces, chopped peanut butter cups, and peanut butter chips!
How to make Peanut Butter Brownies
- Mix together your brownie batter by stirring all the ingredients together in a large bowl. Fold in peanut butter chips.
- Pour mixture into a 9×13-inch pan lined with foil or parchment paper. Add all your Reese’s candies.
- Bake until a toothpick comes out with just a few crumbs.
Expert Tips
- Feel free to swap out the peanut butter chips for chocolate chips.
- You could even top these with peanut butter frosting for even more flavor.
- Cutting brownies with a plastic knife will make your cuts clean!
Storage
Store cooled Reese’s brownies in an airtight container. These are SO good and they not only taste good warm but you can freeze them for later too. I made them ahead and froze them for a party and they tasted just as good as fresh. And EVERYONE loves them!

Recipe Notes
- Store in an airtight container or freeze.
I made these last night and they were VERY undercooked. I even put them back in the oven for an extra 20 minutes and still pure goo in the middle. I followed the recipe to the tee. Any idea what may have gone wrong?
What kind of pan do you use? I can only think that maybe glass vs metal caused the issue? I’ve never had a problem with these – they’re supposed to be gooey but not wet.
