One round cake baked and cooled (this is a 6" round)
White Icing (I used cream cheese icing.)
Sprinkles in red, yellow, blue & clear (or white)
To get a smooth cake with a cream cheese or other "non-crusting" icing, you want to cover the cake with icing, then make as few strokes as possible while turning the cake for the sides, and use few strokes to go around in a circle along the top.
Place the cake in the refrigerator to allow the icing to set so that it won't stick to your template.
