Mix and bake 2 (8-inch) cake layers according to spice cake package directions. Cool completely.

Mix the 2 boxes of chocolate cake together according to package instructions. Bake 2 (6-inch) and 2 (10-inch) cake layers and 1 (7-ounce) ramekin. Cool completely.

In a medium bowl combine white chocolate and 4 drops of green food coloring. Place bowl in microwave and heat at 50 percent power in 20-second intervals until white chocolate is melted and smooth. Dip the sugar cone into the chocolate and spin it around so that it is evenly coated. Remove from bowl and let excess chocolate drip off. Place on a plate lined with waxed paper and let dry.

In a large bowl stir together frosting and about 10 to 12 drops of green food coloring. The icing should be a pale green color. If too light in color, add a few more drops of food coloring. Transfer the icing to plastic releasable bags or a pastry bag. Cut 1/2-inch off the corner of the plastic bags and set aside.

Cut off the top of each layer so that it is flat and even. To assemble cake, place 4-inch by 12-inch strips of parchment paper around the edge of the cake plate or stand. Place 1 (10-inch) cake layer on cake stand on top of the parchment paper. Spread a layer of frosting and top with remaining 10-inch layer. Frost cake with icing.

Place 1 (8-inch) layer on cardboard cake round. Spread an even layer of frosting and top with remaining 8-inch layer. Frost cake with icing and place on top and in the center of the frosted 10-inch cake.

Place 1 (6-inch) layer on a cardboard cake round. Spread with a layer of frosting and top with remain 6-inch layer. Frost cake with icing and place on top and in the center of the frosted 8-inch cake.

Place the small cake that was baked in the 7-ounce ramekin (or the jumbo cupcake) on top of the 6-inch layer and frost with the icing. Place the cone tree on top.

To decorate the cake, first carefully remove the parchment paper from underneath the bottom layer. Using the can of white decorating icing fitted with the star tip make small rosettes around the top and bottom edge of each cake tier and the bottom of the cone tree. Place a small rosette at the top of the cone tree.

Drape the licorice whips like "garland" around the bottom 3 cake tiers using the 6-inch lengths for the top layer, the 8-inch lengths for the middle layer and the 10-inch length for the bottom layer. Using the yellow icing can fitted with a star tip, pipe rosettes where the garland strands meet. Place 1 small rosette on top of the cone tree. Using the red icing fitted with the round tip randomly place small red dots around the cake. Place candles in the yellow icing rosettes between licorice garlands.
