Try this creamy peanut butter frosting on your favorite chocolate cupcakes, brownies, and cakes!
You can generously frost 12 cupcakes or lightly frost 24 cupcakes. It will also frost a 9 x 13 sheet cake or a 2-layer round 9" cake. It is best to use a commercial creamy peanut butter brand instead of a natural or organic brand to avoid separating and curdling.
