These peanut butter cup stuffed brownie bites are oogey gooey at it's finest! While these brownie bites would be great without the peanut butter cups, because they're so moist and fudgy, the Reese's really takes it to the next level! Biting into a rich, chewy brownie, and a melty peanut butter cup is pure heaven.
If you just want plain brownie bites, I'd up the chocolate chips from 1/2 cup to 1 cup!
