Let’s Make it Together
Gather Your Tools: Start by assembling your mixing bowls, spatula, and electric mixer—this frosting won’t whip itself. Make sure everything is clean and ready for action.
Mix Butter and Peanut Butter: In a large bowl, combine room temperature unsalted butter with your choice of peanut butter. Beat until smooth and fluffy for about 2 minutes; it’ll smell heavenly.
Add Powdered Sugar Gradually: Slowly add powdered sugar to the mixture, one cup at a time. Mix on low speed to prevent sugar clouds from forming in your kitchen—your vacuum cleaner will thank you later.
Pour in Vanilla Extract: Add vanilla extract while mixing to create an aromatic boost in flavor. Your kitchen will be filled with scents that could make anyone swoon.
Adjust Consistency with Milk: If your frosting feels too thick, add milk one tablespoon at a time until you reach your desired spreadability. It should be creamy enough to easily spread but not runny.
Taste Test Time!: Grab a spoon (or your finger) and indulge in some quality control. Feel free to add more peanut butter or sugar if needed—it’s all about making it perfect for you!
Now you’re ready to slather this dreamy peanut butter frosting on cakes, cupcakes, or simply enjoy it by the spoonful (no judgment here). With its rich flavor and velvety texture, this frosting will elevate any dessert into something truly special!
