Make this easy vanilla buttercream frosting for a creamy, smooth, and fluffy topping. This American buttercream recipe is perfect for piping decorations on cakes and cupcakes and uses simple ingredients.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 2 to 3 tablespoons heavy cream or milk
  • Pinch of salt

Instructions

  1. Place the softened butter in a large mixing bowl. Beat the butter with an electric mixer on medium speed until it is light and creamy, about 2 minutes.
  2. Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until combined after each addition. Scrape down the sides of the bowl as needed.
  3. Add the vanilla extract and the pinch of salt. Mix on low speed until incorporated.
  4. Add 2 tablespoons of heavy cream or milk. Increase the mixer speed to medium-high and beat for 3 to 5 minutes until the frosting is light and fluffy. This whipping time develops the texture.
  5. If the frosting seems too thick for spreading or piping, add the remaining tablespoon of cream, one teaspoon at a time, until you reach your desired consistency.
  6. Use immediately to frost your cakes or cupcakes.

Notes

  • For the best texture, make sure your butter is truly softened, not melted.
  • Sifting the powdered sugar prevents lumps in your finished frosting.
  • If you need a stiffer frosting for detailed piping work, reduce the liquid slightly.
  • This frosting holds up well at room temperature for serving but store leftovers in the refrigerator.
