What sort of cake would Lucky the Leprechaun enjoy most? One with a colorful rainbow inside, of course. It’s magically delicious!
Four cups of miniature marshmallows can be used instead of the 10-ounce bag of large marshmallows.
All colors needed for the rainbow cake can be made from the three primary colors red, blue and yellow. An orange tint can be made by mixing red and yellow food color; violet can be achieved by mixing red and blue; and green can be made by mixing yellow and blue.
Three 8-inch round cake pans can be used to bake three cakes at once, decreasing the time to make this cake by 20 minutes.
