Mini Peanut Butter Cup Brownies

If you love peanut butter cookie cups you have to try these mini peanut butter cup brownies. Same concept but with brownie instead of peanut butter cookie cups.

I am weak for seasonal items, especially when they can be used in baking. After discovering the “blossom top” Reese’s mini peanut butter cups for Valentine’s Day I knew I had to make something to show them off. Pressing them into cookie cups seemed like the only logical solution.

These mini peanut butter cup brownies not only look a lot like my brownie peanut butter cups but they were adapted from the very same recipe. But instead of peanut butter chips mixed into the brownie batter and then filled with straight peanut butter, these are stuffed with a mini peanut butter cup.

In other words, mini peanut butter cup brownies are essentially peanut butter cookie cups with the peanut butter cookie dough swapped with brownie batter.

The idea to go for the brownie base instead of peanut butter was born from the fact that Valentine’s Day is predominated by all things chocolate. Even though I am not a fan of pure chocolate, I am definitely on board with peanut butter and chocolate together. Which is why I have also made peanut butter cup cookie bars.

Can you make brownie bites with box mix?

Absolutely. The yield and bake time may differ slightly but follow the directions on the box and add the peanut butter cups immediately out of the oven.

Alternatively, you could also mix the peanut butter cups in brownie mix and bake them like a normal pan of brownies. But since these peanut butter cups were pink I like showing them off on top!

Even more alternatively, if you for some reason do not like the peanut butter cup brownie mash-up, maybe instead you would prefer Mississippi mud cookie cups with chocolate cookie dough, marshmallows, and pecans.

Who are you making these Mini Peanut Butter Cup Brownies for this holiday?
