Learn how to make the best classic vanilla buttercream frosting. This American buttercream is smooth, fluffy, and holds its shape perfectly for piping on cakes and cupcakes. It is a quick, no-cook recipe that you will use again and again.

Ingredients

Scale
  • 1 cup (2 sticks or 226g) unsalted butter, softened to room temperature
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 2 to 4 tablespoons heavy cream or milk
  • Pinch of salt

Instructions

  1. Place the softened butter into the bowl of a stand mixer fitted with the paddle attachment (or use a large bowl with a hand mixer). 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. Scrape down the sides as needed.
  3. Add the vanilla extract and the pinch of salt. Mix on low speed until incorporated.
  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, fluffy, and smooth. This whipping time is key for the texture.
  5. Check the consistency. If the frosting seems too stiff for spreading or piping, add the remaining cream or milk, one teaspoon at a time, until you reach your desired texture. If it is too soft, add a little more powdered sugar, one tablespoon at a time.
  6. Use immediately to frost your cakes, cupcakes, or cookies.

Notes

  • For the creamiest texture, ensure your butter is truly at room temperature—soft but not melted.
  • If you are piping intricate designs, use slightly less liquid (cream or milk) for a firmer consistency.
  • To achieve a richer vanilla flavor, use a high-quality pure vanilla extract.
  • If the frosting looks slightly yellow, you can add one tiny drop of white food coloring to make it look whiter, though this is optional.
