Make up the cake mix according to manufacturer’s instructions. Use a half sheet tray extender on a lined half sheet tray. Spray the pan and deposit 6 pounds of batter into prepared pan. Bake at 350°F until cake springs back lightly when touched. Let cool completely. Trim the belly and place on a cake board, trimmed side down. Reserve the belly for cake pops. Smooth ice the top of the cake with white buttercreme. Use Dawn colors to mix a few more shades of greens, oranges and yellows (use a ratio of 1 part Bright Yellow to 5 parts White to make light yellow) then using a set of small pallet knives, decorate the top of the cake in swooshes that make a floral design.
