Make the best vanilla buttercream frosting that is rich, fluffy, and creamy. This easy homemade buttercream recipe guarantees a smooth, pipeable consistency perfect for cakes and cupcakes.

Ingredients

Scale
  • 1 cup (227g) unsalted butter, softened to room temperature
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 24 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 for 3 to 5 minutes until it is pale and very fluffy. Scrape down the sides of the bowl as needed.
  2. Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until fully incorporated after each addition.
  3. Add the vanilla extract and the pinch of salt. Mix on low speed until combined.
  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 airy. This whipping time is key for a fluffy texture.
  5. If the frosting seems too stiff for spreading, add the remaining cream, one teaspoon at a time, until you reach your desired consistency. If it is too soft, add a small amount of extra sifted powdered sugar.
  6. Use immediately for frosting cakes, cupcakes, or cookies.

Notes

  • For the best results and a stable frosting, ensure your butter is truly at room temperature, not melted.
  • Sifting the powdered sugar prevents lumps and helps achieve a smooth vanilla topping.
  • If you need a very stiff frosting for intricate piping, reduce the liquid slightly or add 1 tablespoon of meringue powder to the sugar.
  • This classic vanilla frosting is best used the day it is made for optimal texture.
