Dimensional royal icing poinsettias form an elegant wreath around the sophisticated snowy white fondant-covered two-tiered cake. Delicate buttercream icing bead borders surround both cake tiers while simple dots of icing decorate the top half of each cake tier.
Make flowers 1 day in advance. Prepare royal icing following recipe directions. Tint large portion red and small portion yellow. Use tip 352, 1 5/8 in. lily nail, and red icing in cut decorating bag to make 35 to 40 poinsettias. Use tip 2 and yellow icing to make dot centers. Let dry at least 24 hours.
