Let’s Make it together
Gather Your Tools
Prepare by gathering all your ingredients and tools—mixing bowl, electric mixer, and spatula will help make your life easier.
Cream the Butter and Peanut Butter
In a large mixing bowl, combine softened unsalted butter and peanut butter using an electric mixer until smooth and well-blended. You want it to look fluffy and inviting.
Add in Powdered Sugar
Gradually add powdered sugar into the mixture while mixing on low speed. This prevents a cloud of sugar from covering your kitchen like it’s been hit by a snowstorm.
Pour in Milk and Vanilla
Next, pour in milk and vanilla extract gradually while mixing until you achieve your desired consistency. Aim for creamy but spreadable—think luxurious!
Taste Test
This step is crucial! Dip in a spoon and taste-test for sweetness. Adjust by adding more sugar if needed; after all, life is too short for bland frosting!
Frost Your Treats
Finally, grab your favorite cupcakes or cakes and slather on that glorious peanut butter frosting generously! Enjoy the smiles as they take their first bites.
Now you’ve mastered peanut butter frosting! It’s so versatile that it can be used on cakes, brownies, or even enjoyed straight from the bowl when no one’s looking (we won’t tell!).
