1 (16 ounce) can vanilla frosting
1 (18 ounce) jar peanut butter
Empty entire jar of peanut butter in a mixing bowl.
Heat vanilla frosting in its container (make sure you pull off all the foil lining) in microwave for about 60 seconds or until completely melted.
Pour the melted frosting in the bowl with the peanut butter and mix well.
Quickly pour the mixture into a 9×13 pan, allow fudge to set, cut into small squares, and enjoy!
