What is Brown Sugar Buttercream?

Brown Sugar Buttercream is a classic American-style buttercream made using butter, powdered sugar, and brown sugar instead of white granulated sugar. The brown sugar gives the frosting a delicious caramel taste while keeping it creamy and smooth.

Some recipes include cinnamon for extra warmth, while others rely solely on vanilla to let the brown sugar shine.

Ingredients

You’ll only need a handful of ingredients.

• 1 cup salted butter, softened
• ¾ cup packed light or dark brown sugar
• 4 cups powdered sugar, sifted
• 1 tablespoon pure vanilla extract
• 2–4 tablespoons whole milk or heavy cream
• 1 teaspoon ground cinnamon (optional but recommended)

Ingredient Notes

Butter

Use room-temperature butter for the fluffiest frosting.

Brown Sugar

Choose according to your preferred flavor.

• Light brown sugar: Mild caramel flavor
• Dark brown sugar: Richer molasses taste

Powdered Sugar

Sifting helps create an ultra-smooth buttercream.

Vanilla Extract

Pure vanilla provides the best flavor.

Milk or Heavy Cream

Adjusts the consistency depending on whether you’re spreading or piping.

Cinnamon

Adds cozy warmth and enhances the caramel notes.

How to Make Brown Sugar Buttercream

Step 1: Cream Butter and Brown Sugar

Using a stand mixer or hand mixer, beat the softened butter and brown sugar for 3–5 minutes until light and creamy.

Step 2: Add Vanilla

Mix in the vanilla extract until fully combined.

Step 3: Add Powdered Sugar

Gradually add powdered sugar one cup at a time while mixing on low speed.

Once incorporated, beat on high speed for about 2 minutes until fluffy.

Step 4: Adjust Consistency

Add milk one tablespoon at a time until the frosting reaches your desired consistency.

Step 5: Stir in Cinnamon

Mix in the cinnamon and whip for another 30 seconds.

Your buttercream is now ready to use.
