You can make your own naturally blue colored sugar with homemade natural blue food coloring (made with red cabbage and baking soda).

Stir some natural blue food coloring into sugar – it’ll look almost black at first!

Let the naturally blue colored sugar air-dry. I tried drying the blue sugar in an almost cold oven, but the blue turned olive-green and the heat affected the taste of the red cabbage sugar.

Now have fun with your homemade natural blue sugar: Sprinkle it over cupcakes or cookies! 😀

Here you’ll find my tutorial for naturally colored sugar sprinkles and sugar hearts in all colors of the rainbow.
