2 teaspoons pure lemon extract
5 large egg whites
1 cup sugar
1 cup (2 sticks) unsalted butter, cut into small pieces, room temperature

Steps:

Make the filling and crumb coat: Cook egg whites and sugar in a small saucepan over medium heat, whisking constantly until sugar is completely dissolved. Transfer to the bowl of an electric mixer fitted with the whisk attachment; mix on high speed until mixture is room temperature. With the mixer on medium-low, add butter, one piece at a time, mixing well after each addition.
Remove whisk attachment and switch to paddle attachment. Increase speed to high and beat until buttercream comes together, about 5 minutes; beat in lemon extract.
Make the frosting: In a clean saucepan and bowl of an electric mixer, repeat process in step 1.
