Grab your gel colors. I use Americolor, but feel free to use your brand of choice. Tape two large pieces of parchment on a board, kitchen counter, or a cookie sheet. 

In a bowl of an electric mixer fitted with a paddle attachment, combine powdered sugar, milk (or water), corn syrup and flavoring. Alternatively, you can use a hand mixer, or if you have wicked strong arms or don't believe in modern marvel appliances, do this by hand. Beat at medium speed until the ingredients are combined. Add desired flavoring and continue beating until a thick paste forms. At this time you can add more powdered sugar a tablespoon at a time if the mixture seems to thin or more milk a teaspoon at a time if the mixture looks too thick.

Divide the paste into small bowls and begin tinting with food coloring. A toothpick is best to control how much color will be added to your paste. Mix until you have achieved desired color.

Add the sprinkle paste to piping bags fitted with a #4 #7, and #10 tips. Pipe dots of varying sizes onto the sheet of parchment making sure dots don't touch each other. Pipe lines of varying thickness onto parchment paper. 

Allow to dry overnight.*

Once the sprinkles have dried, break up the lines with either your hands or a knife. I use my hands. Lift the dots from the parchment.

Use as desired.

*You must allow these to dry overnight, otherwise your efforts will be in vain.

Number of servings (yield): Like a million sprinkles! OK, perhaps not a million, but somewhere in the 1000 mark, enough to line the bottom of at least two 8in cakes.

To store: Store in a glass jar with a tight fitting lid. Sprinkles last forever.
