Equipment

  • Kitchen Scale (optional)
  • Stand Mixer

Ingredients

  • 1 cup salted butter 226 grams, room temperature (2 sticks)
  • ¾ cups brown sugar 160 grams
  • 1 tablespoon pure vanilla extract 12 grams
  • 4 cups powdered sugar 452 grams, sifted
  • 2-4 tablespoons whole milk 28-57 grams, room temperature
  • 1 teaspoon ground cinnamon 3 grams

Instructions

  • In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and brown sugar on high speed until creamy, about 3-5 minutes. Mix in the vanilla extract.
    1 cup salted butter, ¾ cups brown sugar, 1 tablespoon pure vanilla extract
    a bowl of ingredients with a spoon and a bowl of flour.
  • Scrape down the sides, then add the powdered sugar one cup at a time, mixing on low speed until incorporated. Scrape the sides again, then increase to high speed and beat for 2 minutes, until light and fluffy.
    4 cups powdered sugar
    a bowl of flour, sugar, and other ingredients on a marble countertop.
  • Add 2 tablespoons of milk and beat well. Add additional milk, if needed, to reach desired consistency.
    2-4 tablespoons whole milk
    mixing frosting ingredients
  • Stir in the ground cinnamon.
    1 teaspoon ground cinnamon
    mixing cinnamon into buttercream

Notes

  • This recipe yields about 2½ cups (40 tablespoons) of frosting.
  • Use light brown sugar for a lighter-tasting frosting and dark brown sugar for a richer, more molasses-y frosting.
  • Try swapping some or all of the vanilla extract for almond, amaretto, maple, or bourbon extract!
  • In place of the whole milk, you can use heavy cream or half-and-half.
  • You can omit the cinnamon for a more plain-flavored frosting.
  • Add other spices to change the flavor, such as pumpkin pie or apple pie spice!
  • Add ½-1 tablespoon of unsweetened cocoa powder for a chocolate brown sugar frosting. 
  • Add chopped pecans, walnuts, or peanuts for a nutty frosting.
  • Add shredded coconut flakes for a sweeter, coconutty frosting.
  • Do not use shortening in place of the butter. It will not have a good flavor.
  • Sift the powdered sugar to remove any lumps.
  • Make sure all of your ingredients are at room temperature for the smoothest frosting.
  • Do not rush the creaming process or you will end up with a gritty frosting!
Storage: Store brown sugar frosting in a Ziplock bag in the refrigerator for up to 1 week or in the freezer for up to 3 months.
