Ingredients

  • 1/4 cup margarine
  • 1 cup sifted confectioners sugar
  • 1/4 cup peanut butter
  • about 1 tablespoon milk

Instructions

  1. Cream the margarine until smooth.
  2. Blend in part of the sifted confectioners sugar.
  3. Add the peanut butter and beat well.
  4. Alternate adding the remaining sugar and milk.
  5. Beat until the frosting reaches a spreading consistency.

Tips & Substitutions

For a smoother frosting, ensure the margarine is at room temperature before creaming. If you prefer a richer flavor, substitute half of the margarine with cream cheese. You can also use natural peanut butter for a healthier option, but it may affect the consistency. If the frosting is too thick, add more milk gradually until desired consistency is achieved.

Serving Suggestions

This peanut butter frosting is perfect for spreading on cakes, cupcakes, or cookies. It pairs beautifully with chocolate cakes or brownies for a decadent treat. For added texture, sprinkle crushed peanuts on top after frosting. It also complements desserts like Fluff 'N Chip Treats and can be used as a dip for fresh fruits like apple slices.

Storage & Reheating

Store leftover peanut butter frosting in an airtight container in the refrigerator for up to one week. Before using, allow it to come to room temperature and re-whip it for the best texture. If you need to extend its shelf life, you can freeze the frosting for up to three months, but make sure to thaw it completely before using.

Frequently Asked Questions

Can I use a different type of fat instead of margarine?

How can I make the frosting less sweet?

To reduce the sweetness, you can decrease the amount of confectioners sugar and add a little more peanut butter or some unsweetened cocoa powder for a chocolatey twist. Alternatively, you can add a pinch of salt to balance the sweetness, enhancing the overall flavor of the frosting.

What desserts can I use this frosting on?

This peanut butter frosting works wonderfully on a variety of desserts, including chocolate cake, vanilla cupcakes, or even as a filling for sandwich cookies. It's also delicious on brownies or as a topping for pancakes, making it versatile for various occasions and sweet treats.
