FLUFFY HARD SAUCE
About 3 ¾ cups
Combine in a large bowl or a stand mixer:
- 2 sticks (8 ounces) unsalted butter, softened
- 3 cups powdered sugar, sifted
- 2 teaspoons vanilla
- ½ teaspoon grated or ground nutmeg
Beat on high speed (with the paddle attachment if using a stand mixer) until light and fluffy but thick enough to hold a firm shape, 6 to 10 minutes. With the beaters running, slowly add:
- ¼ cup brandy, Cognac, dark rum, or orange juice
If desired, add:
- (Grated zest of 1 orange)
Use at once or cover and refrigerate for up to 3 days. Soften the cold sauce at room temperature until spreadable before serving.
