Set Up a Forest
Decorate a buffet table with a trio of snowy cookie trees. Make a base frosting by beating together six egg whites and 3¾ cups confectioners’ sugar. Spread a thin layer of frosting on a Styrofoam cone, then, working up from the bottom, overlap vanilla wafers (use straight pins to hold them in place until the frosting dries). Use a small sieve to dust each finished tree with confectioners’ sugar.
