Mix cake according to manufacturer’s instructions. Measure out 2 pounds batter, deposit 1 pound into a sprayed and papered 8-inch cake pan. Repeat another time to make 2 cakes total. Bake at 350F until cake springs back lightly when touched. Let cool completely. Fill, crumb coat, and smooth ice with white buttercreme. Pipe generous portions of hot pink, light yellow, and white buttercreme around the sides and top of cake, alternating colors to ensure marbled/swirl effect. Smooth ice. Mix together golden yellow and flat icing. Pipe around edges of cake and then into center to create a drip and cover the top of the cake. Decorate with blue buttercreme, fresh flowers, and pink macarons.
