Ingredients

  • 2/3 cup margarine
  • 1 cup powdered sugar
  • 1/2 cup creamy peanut butter

Instructions

  1. Cream the margarine, peanut butter, and 1 cup of powdered sugar until smooth.
  2. Add additional powdered sugar gradually until reaching the desired consistency, usually about another 1 1/2 cups.
  3. Frost a 2-layer cake with the peanut butter frosting.
  4. Best on devil's food cake!

Tips & Substitutions

For a smooth consistency, ensure the margarine is softened before mixing. If you prefer a richer flavor, you can substitute half of the creamy peanut butter with crunchy peanut butter. If you find the frosting too sweet, you can add a pinch of salt or a splash of vanilla extract to balance the flavors. This frosting pairs beautifully with devil's food cake, but it can also enhance a Low-Fat Pound Cake.

Serving Suggestions

This peanut butter frosting is perfect for slathering on a 2-layer cake, but it can also be used as a dip for fresh fruits like apples and bananas. For a fun twist, try using it to frost cupcakes or sandwiching it between cookies for a delightful treat. Pair it with a glass of cold milk or a cup of coffee for a satisfying dessert experience.

Storage & Reheating

Store any leftover frosting in an airtight container in the refrigerator for up to one week. Before using it again, allow it to come to room temperature and give it a good stir to restore its creamy texture. If you need to soften it further, you can briefly microwave it in 5-second intervals, being careful not to melt it.

Frequently Asked Questions

Can I use butter instead of margarine?

Yes, you can substitute butter for margarine in this recipe. Using butter will give the frosting a richer flavor. Just make sure the butter is softened to ensure smooth blending with the peanut butter and powdered sugar.

How can I adjust the sweetness of the frosting?

To adjust the sweetness, you can either reduce the amount of powdered sugar you use or add a small amount of cocoa powder to balance the sweetness with a chocolate flavor. Remember to taste as you go to achieve the desired sweetness.

Is this frosting suitable for vegan diets?

While this recipe uses margarine, which can be vegan, it's important to check that the margarine is free from dairy products. Additionally, ensure that the powdered sugar is not processed with bone char. If you're looking for a vegan alternative, consider using coconut oil or a vegan butter substitute.
