If you don’t have both sizes of round pans, use two 8- or 9-inch rounds.
Decorate the frosted cake with leaf decorations. Press 2 or 3 pieces of different colored gumdrops together. Flatten on a sugar-coated surface, and cut with leaf-shaped cookie cutters. Press the leaves into the frosted cake and cupcakes as desired.
If you have only one pan and a recipe calls for more cupcakes than your pan will make, cover and refrigerate the rest of the batter while baking the first batch. Cool the pan about 15 minutes, then bake the rest of the batter, adding 1 to 2 minutes to the bake time.
