Peanut Butter Frosting

READY IN: 6mins
Recipe by itscolleen

I was making a kid's rich, chocolate birthday cake and tried some experimenting. This turned out FABULOUS and hardens like a royal icing. The color is a light latté color and can be tinted most darker shades. This recipe requires POWDERED/CONFECTIONARY sugar! If you have a granular mess or weird texture it is because you used granular sugar.

Easy to make and good flavor. It was difficult to spread because it did not want to stick to the cake. The finished texture was odd looking. Made exactly as written with creamy Skippy peanut butter and one tablespoon of milk, but it did not harden.
