While the cookies are cooling, make your icing. In the mixing bowl of a stand mixer, blend the cream, vanilla and corn syrup. Add the powdered sugar a little at a time until it’s all been added, and blended.
If the icing is too thin, add a little more powdered sugar, if it’s too thick, add a few more drops of cream, starting with two or three drops.
When you have the desired consistency, divide the icing into one larger bowl, and two slightly smaller bowls. Use the larger bowl for the White icing, (No Food Coloring required for the White Icing), and the small bowls for the Red and Blue icing.
To color the icing, start with a few drops of the gel food coloring, and mix well. If the color is too light, add a little more and stir well until you get the color desired. No food coloring is added to the white icing.
Place the Icing in plastic Pastry bags, and snip off a small amount of the pointed edge, to decorate.
When the cookies have completely cooled, decorate with icing. Allow icing to dry, or set. Serve, and Enjoy!
