You can make this classic American vanilla buttercream frosting that is rich, fluffy, and creamy using simple ingredients. This recipe guarantees a smooth texture ideal for frosting cakes, topping cupcakes, or piping decorations.

Ingredients

Scale
  • 1 cup (227g) unsalted butter, softened to room temperature
  • 4 cups (480g) powdered sugar, sifted
  • 1 tablespoon pure vanilla extract
  • 3 to 4 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 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. Scrape down the sides as needed.
  3. Add the vanilla extract and the pinch of salt. Mix on low speed until incorporated.
  4. Increase the mixer speed to medium-high. Add 3 tablespoons of heavy cream or milk. Beat the frosting for 3 to 5 minutes until it becomes light, fluffy, and smooth. This whipping time builds the volume.
  5. If the frosting seems too stiff for spreading, add the remaining tablespoon of cream, one teaspoon at a time, until you reach your desired consistency. If it is too soft, add a little more sifted powdered sugar.
  6. Use immediately for frosting cakes, cupcakes, or cookies.

Notes

  • For the best texture, ensure your butter is truly softened but not melted. It should yield slightly when pressed.
  • Sifting the powdered sugar prevents lumps and helps you achieve a smooth vanilla buttercream texture faster.
  • If you need a stiffer frosting for intricate piping designs, reduce the liquid slightly or add a small amount of extra sifted powdered sugar.
  • This frosting holds up well at room temperature for serving but store leftovers in an airtight container in the refrigerator. Let it come to room temperature and re-whip before using again.
