Ingredients & Success Tips

Ingredients You’ll Need

• Unsalted butter, softened
• Creamy peanut butter
• Powdered sugar
• Vanilla extract

Tips for Success

• Use room temperature butter: Makes the frosting easier to whip and results in a smooth texture.
• Cream well: Beat butter and peanut butter together until fluffy before adding sugar.
• Adjust consistency: Add a splash of milk if frosting is too thick or extra powdered sugar if too thin.

All About Ingredients and Substitutions

• Butter: Unsalted keeps the sweetness balanced. Salted can be used, but reduce added salt elsewhere.
• Peanut Butter: Creamy works best; natural peanut butter may make the frosting slightly looser.
• Powdered Sugar: Sweetens and thickens the frosting. Can sift before adding to avoid lumps.
• Vanilla: Adds warmth and depth to the flavor.

Variations to Try

• Chocolate Peanut Butter Frosting: Add 2–3 tablespoons of cocoa powder for a chocolate-peanut butter combo.
• Honey Peanut Butter Frosting: Replace some powdered sugar with honey for a softer, naturally sweet flavor.
• Nutty Crunch: Fold in chopped peanuts for texture.
• Salted Peanut Butter Frosting: Sprinkle a pinch of flaky sea salt on top for balance.

Storage Tips

• Store in an airtight container at room temperature for up to 2 days.
• Refrigerate for up to 1 week; bring to room temperature and re-whip before using.
• Freeze for up to 2 months in a sealed container; thaw overnight in the fridge.
