Cutout Cookies

  • 1 cup unsalted butter softened (226g)
  • 2/3 cup granulated sugar (135g)
  • 1 tsp vanilla
  • 1 large egg yolk lightly beaten
  • 2 cups all-purpose flour (270g)
  • 1/3 cup dark cocoa powder (35g)
  • 1/2 tsp salt

Galaxy Glaze

  • 3 cups powdered sugar sifted (375g)
  • 3-4 Tbsp milk
  • 3 Tbsp light corn syrup
  • 1/2 tsp vanilla
  • 1/4 tsp almond extract or your preferred flavoring
  • gel food coloring pink, blue, and purple



  • In stand mixer fitted with paddle attachment, cream butter.
  • Add granulated sugar and beat until light and fluffy.
  • Add vanilla and stir well.
  • Stir in lightly beaten egg yolk. Scrape down sides of bowl as needed to evenly incorporate all ingredients.
  • In separate bowl, combine flour, cocoa powder and salt.
  • With mixer on medium-low speed, gradually add flour until well-incorporated (you will definitely need to scrape down the sides and the bottom of the bowl several times for this, as the mixture is fairly dry and crumbs tend to settle at the bottom of the bowl).
  • Transfer dough to clean surface and use your hands to form it into a cohesive ball.
  • Flatten into a disk (about 1" thick), cover with clear wrap, and chill for 30 minutes.
  • Preheat oven to 350F and line cookie sheet with parchment paper.
  • Once dough has chilled, transfer it to a clean, lightly floured surface and use a lightly floured rolling pin to roll out to about ΒΌ" thickness.
  • Lightly flour your star cookie cutters and cut out your shapes, transferring them to ungreased cookie sheet.
  • Once you have cut out all of the shapes that you can, be sure to re-combine the scraps and roll out and cut out again to get the maximum number of cookies from your dough.
  • Bake on 350F for 10-12 minutes (longer if you are using larger cookie cutters) and allow cookies to cool completely before dipping


  • In a large bowl, combine sifted powdered sugar, 3 Tbsp milk, and light corn syrup. Whisk until smooth. If mixture is too dry, add additional milk, one teaspoon at a time until mixture can be stirred.
  • Stir in extracts (be sure to taste test to ensure you are happy with the flavor!)
  • Glaze should be thick, to test that it is the right consistency drop a few droplets on top of a test cookie. If the glaze remains stiff, it needs to be thinned. If it runs off the cookie, it is too thin and needs more powdered sugar. If it settles down smoothly, it is just right.
  • Divide glaze into four small bowls.
  • Working with one bowl at a time, use a toothpick (a different toothpick for each color) and dip it into the food coloring bottle and then into the glaze. You want a small pool of food coloring about the size of a mini chocolate chip or two.
  • Drag a toothpick through the food coloring and glaze until it is prettily swirled (like a galaxy).
  • Holding your cookie at the base, dip the surface of each cookie into the glaze (take a look at your first cookie -- are you satisfied with the pattern? Adjust whorls with additional food coloring as needed).
  • Optional: Before glaze can harden, immediately after dipping sprinkle cookies with disco dust and silver stars. These make them look extra pretty but are not required for stunning cookies.
  • Once the first bowl runs out or the colors become too muddled together from dipping, move onto your next bowl of food coloring (you will probably need to stir as the surface may have begun to harden).
  • Repeat steps 5-7 until all cookies have been dipped. Allow them to harden at least 30 minutes (may take longer) for glaze to set. Enjoy!
  • Keep uneaten cookies in an airtight container at room temperature.
