How to Make Homemade Peanut Butter Frosting
Step 1: Whip the Butter and Peanut Butter
In a mixing bowl, beat the unsalted butter and creamy peanut butter together using an electric mixer on medium speed for about 1 minute, until light and fluffy.
Step 2: Add the Sweetness and Flavor
Add the powdered sugar and vanilla extract. Beat on low speed until fully incorporated, scraping down the sides as needed to make sure nothing gets left behind.
Step 3: Adjust the Consistency
If the frosting is too thick, add 1 tablespoon of milk or heavy cream and beat again until it reaches your desired creaminess.
Step 4: Frost and Enjoy
Spread generously over cakes, pipe onto cupcakes, or slather over brownies.
