I made these for a cookout this weekend. I glazed them with white icing and then dotted the cookies while the icing was still wet with red- and blue-tinted icings. Then I used a toothpick to swirl the colors around. The results were pretty cool-looking — they reminded me of the trails of color that fireworks leave in the sky as they die out.
The cookies themselves were from the Holiday Cookies recipe from The America’s Test Kitchen Family Baking Book. WPR.org posted the recipe here so I won’t repost it, but it’s one I’ve used before. I love it because it’s easy to work with and the cookies are soft and have great flavor. The icing is the shiny cookie glaze from The King Arthur Flour Baker’s Companion Cookbook.
King Arthur Flour’s Shiny Cookie Glaze
(reposted from Serious Eats, with my adaptations)
3 1/2 cups (14 oz.) confectioners’ sugar, sifted
6 tbs. (3 oz.) milk
1/4 cup (about 1.25 oz.) meringue powder
1 tsp. clear vanilla extract
Wilton icing colors
Place the sifted confectioners’ sugar and meringue powder in a medium-sized bowl. Add the milk and vanilla to the sugar and meringue powder and mix on low for 4 to 5 minutes, until the glaze is the consistency of molasses. Adjust the consistency with a tablespoon of water if necessary. Add icing color if desired. Important: keep the glaze covered while working with it to keep it from forming a skin or hardening up.
Use the spoon for apply the glaze to the cookies and spread using the back of the spoon, removing any excess. Place on a drying rack to let the excess glaze drip off and let the glaze harden and dry for several hours or overnight.
