Put desired amount of sugar in a bowl or ziplock bag.
Mix it up.
Keep going until the color is uniform.
And you're done. How easy was that? I was worried that maybe the sugar and food coloring would turn into goop, or that the colors would bleed once you sprinkled them onto your frosted goodies, but it turned out perfectly. Now sprinkle on your favorite baked good. I prefer mini cupcakes, they are cute and little so you can eat as many as you want.
