Mint Swiss Meringue Buttercream (recipe adapted from marthastewart.com)Makes about 3 cups3 egg whites3/4 cup granulated sugar1/2 cup (1 stick) unsalted butter, at room temperature1 teaspoon peppermint extract1. Put egg whites and sugar in a double boiler over simmering water. Whisking constantly, cook until sugar has dissolved and mixture is warm (about 160 degrees).2. Pour heated egg mixture into a clean bowl of a mixer fitted with the whisk attachment. Beat egg white mixture on high speed until it forms stiff (but not dry) peaks. Continue beating until fluffy and cooled, about 6 minutes (It's very important to beat it for the whole 6 minutes).3. Switch to the paddle attachment. With mixer on medium-low, add butter several tablespoons at a time, beating well after each addition. (If frosting appears soupy or separated after all butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.)4. Beat in peppermint extract. Reduce speed to low; beat 2 minutes to eliminate air bubbles. Stir with a rubber spatula until smooth.
