Peanut Butter Brownie Cups

Chocolate and peanut butter. Is there any better combination? These little bite-sized Peanut Butter Brownie Cups have a brownie exterior filled with a smooth and creamy peanut butter mixture.

They’re bite-sized so you can eat more than just one.

But they’re so good, you may lose track of how many you’ve eaten. But don’t worry. This recipe makes a huge tray full of brownie bites, so no one needs to be the wiser.

Peanut Butter Brownie Bites

Box Of Brownie Mix and Mini Muffin Tin

I used a box brownie mix to keep the recipe simple. For the miniature size, I used a mini-muffin pan. I actually have 2 mini-muffin pans and each one makes 12 mini-muffins.

The muffin tins are filled about 2/3 full with brownie batter and baked. Then you let them cool just slightly and press down in the middle with the back of a spoon or your thumb (I find using my thumb works best.) to form a brownie cup and make room for the peanut butter filling.

Easy Peanut Butter Filling

The peanut butter filling is simply a mixture of creamy peanut butter, cream cheese, powdered sugar and whipped cream. You could use Cool Whip if you don’t feel like whipping your own cream.

I used a plastic bag with the corner snipped off to fill the brownie cups. It goes really fast that way. To make them look pretty, I sprinkled a few mini chocolate chips on top and then they’re ready to eat!

  1. Sounds yummy but before I get started, the recipe says makes 40 brownie bites but the instructions say to use 2- 12 cup mini muffin tins which is 24 brownie bites. Is the serving size of 40 incorrect or do I repeat the baking process a 2nd time or use additionsl tins?
