Prepare cake mixes according to package directions. Divide batter among two greased and floured 9-in. round baking pans, one 9-in. square baking pan and 12 cupcakes. Bake at 350° for 20-25 minutes and cupcakes for 18-20 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
Place one round cake off center and 1 in. from the bottom of a 25x16-in. covered board. Place second round cake above it. Set aside 1 cup vanilla frosting. Frost round cakes with remaining vanilla frosting.
Cut the square cake into two rectangles-one 8-in. x 2-in. and one 8x4-in. (save remaining piece for another use). For hat brim, place the smaller rectangle (B) above on the top round cake. Cut a 5-3/4x4-in. piece from the large rectangle; place (A) above hat brim. For scarf, cut the remaining cake piece in half diagonally (C and D); position on left side of top circle. (Save the cupcakes for another use.)
Frost hat with chocolate frosting. Tint reserved vanilla frosting blue; frost a stripe on hat for ribbon and frost the scarf. Cut three holly leaves from fruit roll-up; place on hat ribbon. Top with tiny tarts for berries. Position red candy coin for nose; add black gumdrops for eyes and buttons. Add licorice bites for mouth.
