Peanut Butter Cup Brownie Muffins

These brownie muffins combine two of my favorite foods – peanut butter and brownies. Both are my kryptonite. These brownies are very simple to make and taste delicious. They are moist, fudgy, and delectable! I can’t get enough of them! I like to put one in a bowl and top it with vanilla ice cream. Holy YUM!

If you don’t have peanut butter cups, you can substitute any flavor baking chips. I’ve made these with semisweet chocolate chips, peanut butter chips, butterscotch chips and even white chocolate chips.  These would be great with some mint or peppermint chips at Christmas time.

The brownies will be making an appearance at our Labor Day feast. I will probably take some to the football game this weekend too! YAY for college football!!
