1) Whisk together sugar, flour, eggs, salt, oil, vanilla, and cocoa powder until well combined. Stir in the semi sweet chocolate chips. Make sure to not over mix!

2) Prepare a mini muffin pan with cooking spray and preheat your oven to 350 degrees F.

3) Scoop batter into the pan.

4) Fill the slots up about - of the way up, so there's a little room for the peanut butter cup stuffed brownie bites to rise.

5) Cook for 8 - 10 minutes, or until an inserted toothpick comes out almost clean. It's ok if these are slightly underdone.

6) Once the brownies are done, gently push a peanut butter cup in the center of the brownie.

7) Let these set in the pan for a couple of minutes.

8) Remove from the pan and let them cool the rest of the way on a cooling rack!
