Ingredients
  

Main Ingredients
  • 1 cup unsalted butter (2 sticks) softened
  • ½ cup shortening
  • 6-8 cups powdered sugar sifted
  • ¼ cup milk (whole or 2% works best)
  • 2 teaspoons pure vanilla extract
  • ½ teaspoon almond extract (optional, but highly recommended)
  • Pinch salt

Equipment

  • Large mixing bowl
  • Electric mixer (stand or hand)
  • Paddle attachment (for stand mixer)

Method
 

Preparation
  1. In a large mixing bowl, beat softened butter and shortening with an electric mixer on medium-high for 5-7 minutes until very pale, light, and airy.
  2. Gradually add 2 cups of sifted powdered sugar on low speed, then increase to medium until smooth; repeat with remaining sugar 1-2 cups at a time.
  3. Once all sugar is in, add milk, vanilla, almond extract (if using), and a pinch of salt; beat on low speed until combined.
  4. Increase mixer speed to medium-high and beat for 5-8 minutes until the frosting is light, fluffy, very pale, and almost doubled in volume.
  5. Adjust consistency by adding a teaspoon of milk if too thick, or a tablespoon of sifted powdered sugar if too thin, beating well after each addition.

Notes

For best results, ensure your butter is truly softened but not melted. If using unsalted butter, you may want to increase the pinch of salt slightly to taste. This frosting can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to a week. If refrigerated, let it come to room temperature and re-whip before using.
