Pumpkin Spice Buttercream

Makes enough to fill and frost a 10-inch cake


  • 8 large egg whites (about 1 cup)
  • 1 cup granulated sugar
  • Pinch of salt
  • 3 cups unsalted butter, at room temperature
  • 15-ounce can pure pumpkin purée
  • 2 tablespoons Madagascar bourbon vanilla
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg


1. In the top pan of a double boiler, heat the egg whites, granulated sugar and salt, whisking constantly, until the sugar is dissolved. Be careful to heat the mixture slowly (to avoid cooking the eggs)!

2. Transfer the mixture to a stand mixer fitted with the whip attachment and whip on high speed until stiff peaks form, about 5 minutes.

3. Reduce the mixer speed to medium and add the butter a little at a time. Add the confectioner’s sugar, pumpkin, vanilla, cinnamon, and nutmeg and mix until incorporated.
