Sprinkles are fairly easy to make and are fun to hand out as gifts! If you want them to be colored, use food coloring gel or liquid (or try experimenting with natural dyes derived from foods like beets, red cabbage, and turmeric). The recipe below will produce plain white sprinkles. Package in a festive little bag or jar.
Sift the powdered sugar through a sieve to get rid of any clumps. Add your extract, if you are using, to the powdered sugar and mix. Add the egg whites and then whip with an electric mixer for 5 – 10 minutes. You’ll want the icing to form a stiff peak. Once you reach this point, feel free to mix in a small amount of coloring, if you are using it.
Lay out a long piece of parchment paper. Transfer the icing to a small plastic bag and snip a small (sprinkle-size) hole in the corner. Squeeze all the icing down to that corner. Pipe the icing out of the bag in thin lines as straight as you can make them (or make different shapes, like dots!). Let the icing set on the parchment paper for 24 hours. You must let the icing set for this long so that they harden enough to be sprinkles. Once they’ve hardened, cut the icing lines into the length of sprinkles that you want and then store in an airtight container.
