Ingredients

Scale
  • 2 ¾ cups (345 g) all-purpose flour (King Arthur recommended)
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (227 g) unsalted butter, softened
  • 1 ½ cups (300 g) granulated sugar (Domino brand recommended)
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons (30 ml) milk, whole or 2% (can substitute almond milk)
  • 4 cups (480 g) powdered sugar, sifted
  • 2 large egg whites or 4 tablespoons pasteurized meringue powder mixed with water
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon light corn syrup (optional)
  • Gel food coloring in robin egg blue and mint green (a few drops each)
  • ½ teaspoon pure vanilla extract (optional)
  • Food-safe small paintbrush or clean toothbrush
  • Additional gel food coloring diluted with a little water for speckles

Instructions

  1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. In a large bowl, beat softened butter and granulated sugar with an electric mixer until fluffy and pale, about 3 minutes.
  4. Beat in eggs one at a time, then mix in vanilla extract.
  5. Gradually add dry ingredients in three additions, alternating with milk, starting and ending with flour. Mix just until combined.
  6. Divide dough into two discs, wrap in plastic, and chill for at least 1 hour.
  7. Roll dough on a lightly floured surface to about ¼ inch (6 mm) thick. Cut shapes with cookie cutters and place 2 inches apart on baking sheets.
  8. Bake for 8-10 minutes until edges just begin to turn golden. Centers will look slightly underdone but will firm as they cool.
  9. Cool cookies on baking sheet for 5 minutes, then transfer to wire racks to cool completely.
  10. Prepare royal icing by beating powdered sugar, egg whites (or meringue powder mixture), lemon juice, and corn syrup until glossy and stiff peaks form, about 7-10 minutes. Adjust consistency with water if needed.
  11. Divide icing into portions. Tint most with robin egg blue, a smaller portion with mint green, and leave some white.
  12. Flood cookies with blue icing and let set slightly for 10 minutes.
  13. Thin mint green and blue icing with water. Dip paintbrush or toothbrush and flick tiny droplets onto dried blue icing to create speckles.
  14. Allow decorated cookies to dry completely for 4-6 hours or overnight.

Notes

Chill dough for at least 1 hour to prevent spreading and make rolling easier. Use fresh egg whites or pasteurized meringue powder for royal icing safety. Adjust royal icing consistency with water or powdered sugar as needed. Practice speckling on parchment before decorating cookies. Avoid overbaking to keep cookies soft. Store decorated cookies in airtight container at room temperature for up to 4 days; freeze undecorated cookies for up to 3 months.
