Nutrition values are an estimate. A standard cake mix gives about 12 to 16 servings, or roughly 4 to 8 cake cups depending on the size of your pan and cups; each cup is generous enough to share. Eat straight away: the sprinkle colours start to bleed into the frosting after a few hours. Freezing is not recommended. A round cookie cutter, biscuit cutter or the open end of a large piping tip can replace the paper cups.
