Aimee’s Recipe Notes

Taste & Texture- creamy texture with a rich, nutty peanut butter flavor!

Ease- Only four ingredients.

Peanut Butter- Use your favorite brand. While I love chunky peanut butter fluffernutter sandwiches, I don’t recommend chunky for frosting.

Yield- this recipe makes enough frosting to cover 12 cupcakes or a 13×9 cake. Easily double for more frosting!

Four Ingredient Frosting

Powdered sugar, butter sticks, milk, and peanut butter in bowls on a white surface, each labeled.

When making frosting, choose the best quality ingredients your can find and afford. Scroll down to the recipe card for full measurements.

  • Unsalted Butter- Use my tips and tricks on how to soften butter. Real butter will give the best flavor for this frosting.
  • Creamy Peanut Butter– Use your favorite brand. Natural peanut butters can be used, just be sure to blend the oil layer COMPLETELY before measuring.
  • Powdered Sugar– Adds the perfect sweetness.
  • Milk- I use whole milk for frosting, but really any variety can work. Add more or less to get your desired texture.

How to Make Peanut Butter Frosting

A mixer blends powdered sugar and peanut butter in a bowl; the second bowl shows the mixture whipped smooth.

The key to creamy frosting is first beating the butter for about 3-4 minutes until pale in color. Then add the sugar, peanut butter, and milk.

Beat an additional 3-4 minutes until super creamy and fluffy.
