Homemade Peanut Butter Frosting Recipe

Pro Tips for Making the Recipe

  • Start Slow with the Sugar: Add powdered sugar gradually to avoid clouds of sugar dust and to better control sweetness.
  • Use Room Temperature Ingredients: Cold butter won’t whip properly, so let it soften before starting.
  • Don’t Overbeat: Once everything is combined and creamy, stop mixing to keep the frosting smooth.
  • Pipe for Presentation: For bakery-style swirls, use a piping bag fitted with a star tip.

How to Serve

This frosting works on just about anything sweet, but here are some pairings that really shine:

  • Classic Pairing: Chocolate cake or cupcakes—because peanut butter and chocolate are a match made in heaven.
  • Brownie Upgrade: Spread over cooled brownies for an indulgent treat.
  • Cookie Sandwiches: Use it between two soft cookies for a fun twist.

Make Ahead and Storage

Storing Leftovers

Keep in an airtight container in the refrigerator for up to 5 days. Bring to room temperature and re-whip lightly before using.

Freezing

Freeze for up to 2 months in a freezer-safe container. Thaw in the fridge overnight, then bring to room temperature before whipping again.

Reheating

Frosting doesn’t require traditional reheating—just let it soften at room temperature for easy spreading.
