My mom is baking a cake for my bday party and I'm wondering how I should decorate it. I have a pic that I drew and was going to turn the pic into edible frosting. I also thought of painting the pic on the cake myself with actual frosting, but I thought that might be hard. Then I thought of using powdered food coloring to sprinkle on the cake to make the picture, but I have no idea how to do that. I'm not sure what to do. The pic is of a nice beach scene that I drew myself. The party is next Saturday, any ideas?
