Swiss Meringue Buttercream for Valentine Cupcakes

  • Yield: Makes 4 cups
Swiss Meringue Buttercream for Valentine Cupcakes


  • 5 large egg whites
  • 1 1/4 cups sugar
  • 2 cups (4 sticks) unsalted butter, room temperature, cut into pieces
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon coarse salt


  1. Combine egg whites and sugar in the heatproof bowl of an electric mixer. Set the bowl over a pan of simmering water. Whisk constantly until sugar has dissolved and whites are hot to the touch, about 5 minutes.

  2. Transfer the bowl to the electric mixer. Using the whisk attachment, beat until stiff, glossy peaks form, about 10 minutes.

  3. At low speed, add butter, one piece at a time, to egg whites, and beat until smooth. Add vanilla and salt, and beat to combine.
