Ways to Serve
Show them off on layered stands with berries and mint leaves. Make fancy place settings at parties by matching them with handmade notes. Set them up in heart shapes to create eye-catching displays.
Mix It Up
Switch to almond or rose flavor instead of vanilla. Put fruit flavor in the filling. Pick different colors for coating. Throw in a layer of ganache if you're into chocolate.
