Ingredients You’ll Need
Gathering the right ingredients is half the fun because each one plays such an important role in creating the perfect texture and irresistible taste of this Peanut Butter Frosting Recipe. From creamy peanut butter that adds deep flavor to the smooth butter that balances it out, every element is essential.
- ½ cup unsalted butter (softened): Provides the creamy base and makes the frosting smooth and spreadable.
- 1 cup creamy peanut butter: The star ingredient that delivers that rich, nutty essence everyone loves.
- 2 cups powdered sugar: Sweetens and thickens the frosting to just the right consistency.
- 2–4 tablespoons milk or heavy cream: Adjusts the frosting’s texture for fluffiness and spreadability.
- 1 teaspoon vanilla extract: Adds a warm, aromatic layer of flavor that complements the peanut butter.
- Pinch of salt (optional): Enhances the overall flavor by balancing sweetness and boosting the peanut butter’s richness.
How to Make Peanut Butter Frosting Recipe
Step 1: Cream Butter and Peanut Butter
Start by beating the softened butter and creamy peanut butter together in a large mixing bowl. This step is key because it creates the rich, velvety base for your frosting, ensuring it’s perfectly smooth and full of peanut butter goodness.
Step 2: Add Vanilla and Salt
Next, stir in the vanilla extract along with a pinch of salt if you like. The vanilla gives your frosting a lovely depth, while the salt gently cuts through the sweetness, making every bite irresistibly balanced.
Step 3: Gradually Beat in Powdered Sugar
Add the powdered sugar a half cup at a time, beating well after each addition. This slow incorporation helps prevent lumps and guarantees a silky texture that’s just sweet enough without being overpowering.
Step 4: Adjust with Milk or Cream
Finally, pour in the milk or heavy cream one tablespoon at a time and beat until your frosting reaches that coveted fluffy, spreadable consistency. This is where you can customize the texture to perfectly suit cakes, cupcakes, or cookies.
