Brown Sugar Buttercream

Ingredients

• 4 large egg whites
• 1 cup packed light-brown sugar
• 1/4 teaspoon salt
• 1 1/2 cups (3 sticks) unsalted butter, room temperature, cut into tablespoons

Instructions

1 _ In a heatproof bowl set over (not in) a pan of simmering water, whisk together egg whites, sugar, and salt. Cook, whisking constantly, until the sugar has dissolved and the mixture is warm to the touch.

2 _ Transfer to the clean bowl of an electric mixer. Beat on medium speed until fluffy and cooled, about 15 minutes.

3 _ Raise speed to high; beat until stiff peaks form. Reduce speed to medium-low; add butter, 2 to 3 tablespoons at a time, until fully incorporated.
