You need a reliable, smooth, and fluffy vanilla buttercream frosting that holds its shape for decorating cakes and cupcakes. This American buttercream recipe is quick to make and uses simple ingredients for that rich, classic flavor.

Ingredients

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

Instructions

  1. Place the softened butter in the bowl of a stand mixer fitted with the paddle attachment. Beat the butter on medium speed until it is completely smooth and creamy, about 2 minutes. Scrape down the sides of the bowl.
  2. Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until just combined after each addition. This prevents a sugar cloud in your kitchen.
  3. Add the vanilla extract and a pinch of salt. Mix on low speed until incorporated.
  4. Add 3 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, fluffy, and smooth. This whipping time is key for texture.
  5. Check the consistency. If the frosting seems too stiff for spreading or piping, add the remaining tablespoon of cream, one teaspoon at a time, until you reach your desired consistency. If it is too soft, add a little more sifted powdered sugar.
  6. Use immediately to frost your cakes, cupcakes, or cookies.

Notes

  • For the smoothest texture, ensure your butter is truly at room temperature—soft but not melted.
  • If you are piping intricate designs, use only 3 tablespoons of liquid initially to keep the frosting firm.
  • If the frosting seems grainy, continue beating it for an extra minute or two; the friction helps dissolve the sugar.
  • This recipe makes enough frosting to cover one 8-inch two-layer cake or about 18 standard cupcakes.
