WonderLab’s Galaxy Cookies
This recipe will make at least two dozen cookies, but can be cut in half for a smaller batch.
2 c. unsalted butter (room temperature)
2 c. sugar
2 large eggs
1 tsp. iodized salt
1 T. vanilla extract
5 c. all-purpose flour
Preheat oven to 350º F. Combine butter and sugar using a stand or hand mixer. Add eggs one at a time and mix. Mix in salt and vanilla. Add flour and mix carefully until just combined. Roll out on a floured surface to 1/4 – 3/8 inch thick. Use a heart-shaped cookie cutter or a knife to cut out cookies. Chill for at least 10 minutes. Bake on parchment-lined baking sheets for 10-12 minutes, until edges are golden brown and center no longer looks wet.
(Don’t forget to cut the icing recipe in half if you do it for the cookies!)
3 cups powdered sugar
3-4 tbsp milk
3 tbsp light corn syrup
3/4 tsp vanilla or 1/2 tsp vanilla + 1/4 tsp almond extract
Red and blue food coloring
Combine powdered sugar, milk, light corn syrup, and extract(s). Whisk or mix with a hand or stand mixer until smooth. Scoop up some icing with a spoon and let it drizzle into the bowl. You should be able to see where you drizzled the icing for about 10 seconds. If it’s too thick, add milk a couple drops at a time. If it’s too thin, add more powdered sugar.
Divide icing into four medium sized bowls and cover three of them so they don’t dry out. Starting with the uncovered bowl, add in drops of blue and red food coloring and swirl around with a toothpick, until it has a galaxy-like pattern. (You can also mix food coloring into different shades of purple before adding them to the icing for a more varied pattern!) When you like the way your galaxy looks, dip the surface of each cookie into the glaze and then set aside to dry. After several cookies, when the first bowl gets too muddled, move on to the second one and create a whole new galaxy!
