Reese's cup cakes

Ingredients:

Peanut Butter Frosting

*1/2 cup butter (Make SURE it is at room temp)
*1 cup peanut butter
*4 cups powdered sugar
*1/3 cup milk

Instructions:

1. Cream butter and peanut butter until smooth
2. Add powdered sugar and milk alternatively
3. I normally add more milk to make the frosting more creamy because if you dont it ends up being very thick.
