Caramel Cashew Swiss Meringue Buttercream

Ingredients

  • cup swerve brown sugar (or other on plan brown sugar like this one from Gwen's-Nest.) See notes for measuring Swerve brown sugar.
  • 3 large egg whites
  • ½ teaspoon salt
  • 1 cup butter, softened and cut into 1-tablespoon pieces
  • ½ teaspoon vanilla extract
  • ¾ t. caramel extract (Feel free to swap out for another flavoring!)
  • 1 cup cashew butter (You may use any nut butter in this. Peanut butter is DELICIOUS!)

Instructions

  • Combine sweetener, egg whites, and salt in bowl of stand mixer; place bowl over pan of simmering water. Whisking gently but constantly, heat mixture until slightly thickened, foamy, and registers 150 degrees on instant-read thermometer, 2 to 3 minutes.
  • Place bowl in stand mixer fitted with whisk attachment. Beat mixture on medium speed until consistency of shaving cream and slightly cooled, 1 to 2 minutes.
  • Add butter, 1 piece at a time, until smooth and creamy. (Frosting may look curdled after half of butter has been added; it will smooth with additional butter.) Once all butter is added, add vanilla and cashew butter; mix until combined. Increase speed to medium-high and beat until light, fluffy, and thoroughly combined, about 30 seconds, scraping beater and sides of bowl with rubber spatula as necessary.
  • If final frosting seems too thick, warm mixer bowl briefly over pan of simmering water. Place bowl back on mixer and beat on medium-high speed until creamy.

Notes

If you don’t have Swerve brown sugar, just use the equivalent of sweetener of your choice, and add a small amount (1/4-1/2 t. of blackstrap molasses).
When measuring the brown sugar, crumble it into your measuring cup and then lightly level it off. If you pack it in it will be VERY sweet!
This frosting can be made up to 24 hours in advance and refrigerated in an airtight container. When ready to frost, place frosting in a microwave-safe container and warm briefly on high power until just slightly softened, 5 to 10 seconds. Once warmed, stir until creamy.
