These easy decorated Halloween sugar cookies with royal icing look like you spent hours, but come together with smart shortcuts. The royal icing sets up perfectly glossy, the cookies hold their shape, and the decorating is the best part—no piping bags required if you don’t want them.

Ingredients

Scale
  • 3 cups (360g) all-purpose flour
  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 large egg, room temperature
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 4 cups (480g) powdered sugar
  • 3 tablespoons meringue powder
  • 56 tablespoons warm water
  • 1/2 teaspoon vanilla extract (optional, for icing)
  • Gel food coloring (Americolor or Wilton)
  • Sprinkles (orange, black, Halloween shapes)
  • Edible glitter
  • Sanding sugar

Instructions

  1. Make the cookie dough. In a large bowl, cream together the softened butter and granulated sugar until light and fluffy—about 3 minutes with a hand mixer. Add the egg and vanilla extract, mixing until combined. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Don’t overmix.
  2. Chill the dough. Divide the dough in half, shape into discs, wrap tightly in plastic wrap, and refrigerate for at least 1 hour (or overnight).
  3. Preheat and prepare. When ready to bake, preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  4. Roll and cut. On a lightly floured surface, roll one disc of dough to about 1/4-inch thickness. Cut out Halloween shapes and place about 2 inches apart on prepared baking sheets. Gather scraps, re-roll, and cut more cookies.
  5. Bake for 8-10 minutes, or until edges are just barely golden. Centers should look set but not brown. Cool on baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Do not ice warm cookies.
  6. Make the royal icing. In a large bowl, combine powdered sugar and meringue powder. Add 5 tablespoons warm water and vanilla extract. Beat on low speed until combined, then increase to medium-high and beat for 5-7 minutes until thick, glossy, and forms stiff peaks. Add more water, 1 teaspoon at a time, if too thick.
  7. Divide and color. Separate icing into bowls for each color. Use gel food coloring—just a tiny dab on a toothpick. For outlining, keep icing thick (15-second consistency). For flooding, thin with water a few drops at a time until it flows smoothly and settles flat in about 15 seconds.
  8. Decorate the cookies. Fit piping bags or squeeze bottles with small tips (or snip a tiny corner). Outline each cookie first, then flood the inside with thinned icing. Use a toothpick to spread icing into corners and pop air bubbles. Add sprinkles or decorations while icing is still wet. Let decorated cookies dry completely—4-6 hours at room temperature.
  9. Dry and store. Once icing is completely hard to the touch, store in an airtight container at room temperature for up to 2 weeks. Layer between sheets of parchment paper.

Notes

Don’t skip the chill time—warm dough spreads. Flour your rolling pin and surface lightly. Use the 15-second test for icing consistency. Work in batches when decorating. Keep a damp paper towel over icing bowls to prevent crusting. Let cookies dry at room temperature—do not use a fan. Cookies taste better the next day. Store undecorated cookies up to 2 weeks; decorated cookies up to 1 week. Freeze unbaked dough or baked undecorated cookies for up to 3 months.
