This recipe for perfect decorated Halloween sugar cookies with royal icing is the one I’ve tested more times than I care to admit. The royal icing sets up perfectly hard and shiny, the sugar cookie base is sturdy enough to hold all that decoration without crumbling, and the flavor—buttery, vanilla-kissed, with just a hint of almond—is the kind of classic that never gets old.

Ingredients

Scale
  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • ½ teaspoon almond extract
  • 2½ cups (312g) all-purpose flour
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • 4 cups (480g) powdered sugar, sifted
  • 3 tablespoons meringue powder
  • 5–6 tablespoons warm water
  • ½ teaspoon vanilla extract (for icing)
  • Gel food coloring (assorted Halloween colors)

Instructions

  1. Make the cookie dough: In your stand mixer fitted with the paddle attachment, cream together the softened butter and granulated sugar on medium speed until light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl. Add the egg, vanilla extract, and almond extract, and beat until well combined, about 1 minute.
  2. Mix the dry ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, mixing just until the dough comes together. Don’t overmix, or your cookies will be tough. The dough should look crumbly at first, then come together into a smooth ball.
  3. Chill the dough: Divide the dough in half, flatten each half into a disc about 1 inch thick, wrap tightly in plastic wrap, and refrigerate for at least 1 hour. This step is non-negotiable. Chilling prevents the cookies from spreading and makes the dough easier to roll out.
  4. Preheat and prepare: When you’re ready to bake, preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper or silicone mats.
  5. Roll and cut: On a lightly floured surface, roll out one disc of dough to about ¼-inch thickness. I like to use two ¼-inch wooden dowels as guides to ensure even thickness. Cut out your Halloween shapes and carefully transfer them to the prepared baking sheets, spacing them about 1 inch apart. Gather the scraps, reroll, and cut more cookies.
  6. Bake: Bake for 8-10 minutes, or until the edges are just barely starting to turn golden. The centers should look set but not browned. For smaller cookies, check at 7 minutes. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. They must be 100% cool before you start icing them.
  7. Make the royal icing: In the bowl of your stand mixer (or using a hand mixer), combine the sifted powdered sugar and meringue powder. Add 5 tablespoons of warm water and the vanilla extract. Beat on low speed until combined, then increase to medium-high speed and beat for 5-7 minutes, until the icing is thick, glossy, and forms stiff peaks. If it’s too thick, add water a teaspoon at a time. If it’s too thin, add more sifted powdered sugar.
  8. Prepare the icing for decorating: Divide the icing into separate bowls for each color you’re using. Add gel food coloring a little at a time until you reach your desired shade. For the ‘flooding’ consistency (the thin icing you use to fill in shapes), add water a few drops at a time until the icing flows off a spoon and the surface smooths out within about 10 seconds. This is the ’10-second count’ I mentioned earlier. For outlining, keep the icing thicker—it should hold a stiff peak when you lif…
  9. Decorate the cookies: Fit your piping bags with tips—use a #2 tip for outlining and a #3 tip for flooding. Outline each cookie first with the thicker icing, then fill in the center with the flooding icing. Use a toothpick to spread the icing into corners and pop any air bubbles. Let the base layer dry completely (about 2-4 hours) before adding details like dots, stripes, or spider webs.
  10. Add details: Once the base layer is dry, use the thicker icing to add details—eyes on ghosts, stems on pumpkins, stripes on cats. Let everything dry completely, ideally overnight, before stacking or storing the cookies.

Notes

The biggest mistake is overbaking—pull cookies when edges just barely start to turn golden. Sift powdered sugar for royal icing to avoid lumps. Add water to icing a few drops at a time for flooding consistency. Work in an assembly line: outline all cookies first, then flood. Humidity affects drying time; avoid decorating on rainy days. Cookies taste better the next day.
