Ingredients

Scale
  • 1 cup unsalted butter, softened to room temperature
  • 4 cups powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 2-4 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 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 incorporated. Increase the speed to medium-low and beat until combined.
  3. Add the vanilla extract and the pinch of salt. Mix well.
  4. Add the heavy cream or milk, one tablespoon at a time, beating on medium speed until you reach your desired consistency. If you want a stiffer frosting for piping, use less liquid. If you want a softer frosting for spreading, use more liquid.
  5. Once the liquid is added, 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 to removing any graininess.
  6. Use immediately for frosting cakes or cupcakes.

Notes

  • For the smoothest texture, ensure your butter is truly softened but not melted. Cold butter will result in lumps.
  • Sifting the powdered sugar prevents lumps in the final product.
  • If the frosting seems too soft after mixing, chill it for 10 minutes before using it for piping.
  • To make a stable buttercream for warm weather, substitute 1/4 cup of the butter with vegetable shortening.
