Make this easy vanilla buttercream frosting for creamy, smooth, and fluffy results perfect for piping on cakes and cupcakes. This classic recipe is a baking essential.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened to room temperature
  • 4 cups powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 2 to 4 tablespoons heavy cream or whole 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.
  3. Add the vanilla extract and the pinch of salt. Mix on low speed until incorporated.
  4. Add the heavy cream or milk, starting with 2 tablespoons. Beat the frosting on medium-high speed for 3 to 5 minutes until it becomes light, fluffy, and smooth. If the frosting seems too stiff for spreading or piping, add the remaining cream, one teaspoon at a time, until you reach your desired consistency.
  5. If the frosting is too soft, add a little more sifted powdered sugar, one tablespoon at a time.
  6. Use immediately to frost cakes, cupcakes, or cookies.

Notes

  • For the smoothest texture, ensure your butter is truly softened but not melted.
  • If you need a stiffer frosting for detailed piping, reduce the amount of liquid slightly or increase the powdered sugar.
  • For a richer vanilla flavor, use high-quality pure vanilla extract.
