Ingredients

Scale
  • 2 ¾ cups (345 grams) all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (227 grams) unsalted butter, softened
  • 1 cup (200 grams) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • ½ teaspoon almond extract (optional)
  • 4 cups (480 grams) powdered sugar, sifted
  • 3 tablespoons pasteurized egg whites or 6 tablespoons meringue powder mixed with water
  • 1 tablespoon fresh lemon juice
  • Water (as needed)
  • Gel food coloring

Instructions

  1. Mix dry ingredients: In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  2. Cream butter and sugar: Using an electric mixer, beat softened butter with granulated sugar until light and fluffy, about 3-4 minutes.
  3. Add egg and extracts: Beat in egg, vanilla extract, and optional almond extract until fully combined.
  4. Incorporate dry ingredients: Gradually add flour mixture to wet ingredients, mixing on low speed until just combined.
  5. Chill the dough: Divide dough into two disks, wrap in plastic wrap, and refrigerate for at least 1 hour or overnight.
  6. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  7. Roll and cut dough: Roll out one disk to about ¼ inch thickness. Use graduation-themed cookie cutters to cut shapes. Transfer to baking sheets, spacing 1 inch apart. Repeat with second disk.
  8. Bake cookies: Bake for 8-10 minutes, rotating sheets halfway through. Cookies should be set around edges with no color change on top.
  9. Cool completely: Let cookies cool on baking sheets for 5 minutes, then transfer to wire rack to cool fully before decorating.
  10. Prepare royal icing: Beat powdered sugar, egg whites or meringue powder, and lemon juice. Add water a teaspoon at a time to reach piping consistency. Divide and color with gel food coloring.
  11. Decorate cookies: Outline each cookie with thicker icing using a piping bag with a small round tip. Let outline dry for 10 minutes. Flood inside border with thinner icing. Use a toothpick or scribe tool to spread icing evenly and pop air bubbles. Add details once base layer is dry. Allow cookies to dry completely (several hours or overnight) before stacking or packaging.

Notes

Keep royal icing covered with damp towels to prevent drying out while decorating. Clean scribe tool or toothpick between colors to avoid mixing. Chill dough well to prevent spreading. Use gel food coloring to avoid thinning icing. Let icing dry fully between layers and after decorating for best results.
