Ingredients
  

Main Ingredients
  • 1 cup unsalted butter 2 sticks, softened to room temperature
  • 3-4 cups powdered sugar sifted, adjust to desired consistency and sweetness
  • 1 tsp vanilla extract
  • 2-4 tbsp heavy cream or milk adjust as needed for consistency
  • 1/4 tsp salt optional, to balance sweetness

Equipment

  • Stand Mixer
  • Large Mixing Bowl
  • Spatula
  • Sifter

Method
 

Prepare the Butter
  1. In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the softened unsalted butter on medium speed for 2-3 minutes until it is light, fluffy, and pale in color. Scrape down the sides of the bowl as needed.
Add Sugar Gradually
  1. With the mixer on low speed, gradually add the sifted powdered sugar, one cup at a time. Mix until each addition is fully incorporated before adding more. This prevents a sugar cloud and ensures smooth mixing.
Incorporate Flavor and Liquid
  1. Once all the powdered sugar is added, stir in the vanilla extract and salt (if using). Add 2 tablespoons of heavy cream or milk and mix on low speed until combined.
Achieve Desired Consistency
  1. Increase the mixer speed to medium-high and beat for another 3-5 minutes, adding more heavy cream or milk one teaspoon at a time until the frosting reaches your desired consistency – smooth, creamy, and spreadable. The longer you beat it, the lighter and fluffier it will become.
Use or Store
  1. Use the American buttercream frosting immediately to decorate cakes, cupcakes, or other baked goods. If desired, you can add food coloring at this stage.

Notes

For a super smooth buttercream, ensure your butter is truly at room temperature (soft but not melted). If the frosting appears too thick, add more liquid 1 teaspoon at a time. If it's too thin, add more sifted powdered sugar 1/4 cup at a time. This buttercream can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 1 week. Bring to room temperature and re-whip before using if refrigerated.
