Light vs. dark brown sugar
Both light and dark brown sugar contain molasses, but dark brown sugar contains more. This means dark brown sugar has more moisture and a stronger flavor than light brown sugar.
The dark brown sugar helps give this frosting a rich, caramel flavor, so we suggest sticking with the dark sugar for best results.
Brown sugar buttercream recipe
- 1 cup firmly packed dark brown sugar
- 1/3 cup water
- ¼ teaspoon salt
- 1½ cups (3 sticks) unsalted butter, softened
- 3 cups confectioners’ sugar
How to make brown sugar frosting
In a small saucepan, combine the dark brown sugar and the water. Bring it to a boil over medium-high heat, stirring constantly.
Once the sugar has dissolved, reduce the heat to medium and continue cooking for about 1 minute. Remove from the heat.
Using a clean silicone spatula, stir in the salt.
Transfer the mixture to a heat-proof bowl, cover and let cool completely to room temperature (it should take about 3 hours).
In a large bowl, beat the butter and brown sugar syrup together until smooth.
Gradually add the confectioners’ sugar, 1 cup at a time, beating well after each addition. Be sure to scrape down the sides of the bowl as needed to make sure everything incorporates.
Once all the sugar has been added, continue beating until the buttercream is light and fluffy, about 1 to 2 more minutes.
Once fluffy, you’re ready to swirl, pipe and decorate!
Can I cool the syrup in the refrigerator?
If you’re in a rush and want to cool the sugar syrup faster, you can cool it in the refrigerator, but only to room temperature. If it’s left in the refrigerator for too long, it may harden and become unusable.
How to store brown sugar buttercream
This brown sugar frosting can be stored in an airtight container in the refrigerator for up to 2 weeks. It can also be frozen for up to 6 weeks.
When ready to use, let the buttercream slowly defrost in the refrigerator overnight, then bring it to room temperature. Rewhip before piping or decorating.
