This Cinnamon Brown Sugar Buttercream Frosting is full of fall flavors and makes a creamy frosting with a little crunch from the brown sugar. It’s the best topping for all your fall-flavored cakes, like pumpkin, spice, apple, and snickerdoodle!
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
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
Add 2 tablespoons of milk and beat well. Add additional milk, if needed, to reach desired consistency.
2-4 tablespoons whole milk
Stir in the ground cinnamon.
1 teaspoon ground cinnamon
Notes
Yield: This recipe makes 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.Tips:
Make sure all of your ingredients are at room temperature for the smoothest 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.
Do not rush the creaming process or you will end up with a gritty frosting!
If your buttercream frosting is too thin, chill it for 10-20 minutes, then whip again. If it is still too thin, add powdered sugar, 1 tablespoon at a time, until it reaches the desired consistency.
If your buttercream is too thick, add milk, 1 tablespoon at a time, until it reaches the desired consistency.
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.
