This is the foolproof recipe for ultra-smooth vanilla buttercream frosting. You will achieve a creamy, fluffy texture perfect for coating cakes or piping decorations, ready in under 15 minutes.

Ingredients

Scale
  • 1 cup (226g) unsalted butter, softened to room temperature
  • 3 1/2 cups (420g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon salt
  • 2 to 4 tablespoons heavy cream or milk

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 3 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 salt. Mix on low speed until incorporated.
  4. Increase the mixer speed to medium-high. Add 2 tablespoons of heavy cream or milk. Beat for 3 to 5 minutes until the frosting is light, fluffy, and smooth. This whipping time is key for a non-grainy 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 few more tablespoons of sifted powdered sugar.
  6. Use immediately for topping cakes or piping decorations.

Notes

  • For the smoothest results, always use room temperature butter; cold butter will result in lumps.
  • Sifting the powdered sugar prevents graininess in your final frosting.
  • If your kitchen is warm, chill the finished buttercream for 10 minutes before piping to help it hold sharp edges.
