Tips for Making Easy Peanut Butter Frosting
Make sure your butter is softened at room temperature. If your butter is too hard, your buttercream will not be smooth and creamy.
Do NOT use natural peanut butter. It’s best to use creamy peanut butter. Both JIF and Skippy will work in this recipe. If you use natural peanut butter, the buttercream will end up too oily.
Use creamy peanut butter instead of chunky peanut butter. Chunky peanut butter will still taste good, but since there are bits of peanuts in it, the frosting will not pipe and spread easily on cake or cupcakes.
