Ingredients

Scale
  • 1 cup unsalted butter, softened to room temperature
  • 4 cups powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • 2 to 4 tablespoons whole milk or heavy cream
  • 1/4 teaspoon 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 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.
  3. Add the vanilla extract and salt. Increase the mixer speed to medium-high and beat for 3 minutes until the mixture is light and fluffy. Scrape down the sides again.
  4. Add 2 tablespoons of milk or cream. Beat on medium-high speed for another 2 to 3 minutes until the frosting is smooth and reaches your desired consistency. If the frosting seems too stiff for spreading, add the remaining milk one teaspoon at a time until you achieve the perfect texture for your needs.
  5. If you need a stiffer consistency for detailed piping, reduce the liquid slightly or add a tablespoon more powdered sugar. Beat for one final minute to incorporate air for maximum fluffiness.

Notes

  • For the smoothest texture, ensure your butter is truly at room temperature—soft but not melted.
  • Sifting the powdered sugar prevents lumps, which helps achieve a flawless, smooth vanilla buttercream.
  • If the frosting seems too soft for piping, chill it in the refrigerator for 15 minutes before using.
  • To achieve a richer vanilla flavor, use high-quality vanilla extract.
