Ingredients for Peanut Butter Frosting

• Peanut Butter – Use regular peanut butter and avoid the ‘natural’ brands that tend to separate easily. Creamy or crunchy is up to the cook as either will work in this recipe!
• Butter – Use unsalted butter in this recipe. I usually add a pinch of salt to frosting but the peanut butter will already contain a little bit.
• Powdered Sugar – Also known as confectioners’ sugar, it is added for consistency and sweetness.
• Milk – Milk (or heavy cream) gives this frosting just the right texture.
• Vanilla Extract – Adds flavor.

Variations – Add a little cocoa powder for a new layer of flavor.

How to Make Peanut Butter Frosting

1. Beat butter and peanut butter until fluffy.
2. Add milk and vanilla (as per the recipe below).
3. Gradually beat in the powdered sugar until the frosting is smooth and fluffy.

Ways to Use Peanut Butter Icing

Everything goes with peanut butter, especially chocolate and bananas! Ice your favorite chocolate brownies, or chocolate cupcakes. Dress up a slice of banana bread.

Best Way to Store Peanut Butter Frosting

Keep leftover peanut butter frosting in a covered container in the refrigerator for up to 3 days or freeze for up to a month. Use leftover frosting to make molasses cookie sandwiches, or spread some up into a pumpkin roll.
