  • 2 1/2 cups (315 g) all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup (170 g) unsalted butter, softened
  • 1 cup (200 g) granulated sugar
  • 1 large egg
  • 2 teaspoons pure vanilla extract
  • 1/2 teaspoon almond extract (optional)
  • 3 cups (360 g) powdered sugar, sifted
  • 2 large egg whites or 4 tablespoons meringue powder + 6 tablespoons water
  • 1/2 teaspoon vanilla extract or lemon juice
  • Green gel food coloring
  • Shamrock-shaped cookie cutter
  • Sprinkles or edible glitter (optional)

Instructions

Step 1: Prepare the dry ingredients
In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
Step 2: Cream butter and sugar
In a large bowl, beat the butter and sugar until light and fluffy, about 2–3 minutes.
Step 3: Add wet ingredients
Add the egg, vanilla extract, and almond extract (if using); mix until combined.
Step 4: Combine dough
Gradually add the dry ingredients to the wet ingredients, mixing just until incorporated.
Step 5: Chill the dough
Divide dough in half, shape into disks, wrap in plastic wrap, and chill for at least 1 hour.
Step 6: Preheat and prepare
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Step 7: Roll and cut
Roll dough out on a lightly floured surface to 1/4-inch (6 mm) thickness. Cut out shamrock shapes and place on prepared baking sheets.
Step 8: Bake
Bake for 9–11 minutes, or until edges are just beginning to turn golden. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Step 9: Make royal icing
In a large bowl, beat together powdered sugar, egg whites (or meringue powder and water), and vanilla or lemon juice until stiff peaks form and the icing is glossy, about 5 minutes.
Step 10: Tint icing
Divide icing into bowls and tint with green gel food coloring as desired.
Step 11: Decorate
Transfer icing to piping bags fitted with small round tips. Outline and flood cooled cookies. Decorate with sprinkles or glitter if desired. Let icing set for at least 1 hour before serving or packaging.

Zusatztipps für die Zubereitung

For best results, let cookies cool completely before icing to prevent the icing from melting or sliding off. Royal icing can be made ahead and kept covered at room temperature for up to 2 days; simply stir before using to restore consistency. The almond extract adds a subtle flavor that complements the vanilla beautifully, but it can be omitted if you have nut allergies or prefer a pure vanilla taste. When rolling out the dough, work with one disk at a time and keep the other refrigerated to maintain the dough's firmness. If the dough becomes too soft while cutting shapes, pop it back in the fridge for 10–15 minutes.

Varianten und Anpassungen

This recipe is wonderfully adaptable to suit different dietary needs and preferences. For vegan cookies, substitute a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) for the egg and use a vegan butter alternative, then follow a vegan royal icing recipe using aquafaba instead of egg whites. You can also experiment with different cookie cutter shapes beyond shamrocks—think leprechaun hats, rainbows, or pots of gold. For a citrus twist, replace the almond extract with lemon or orange zest. The royal icing can be tinted in multiple shades of green or even white and gold for elegant color combinations. Add a touch of sparkle with edible gold dust or pearl sprinkles for an extra festive touch.

Serviervorschläge

These shamrock sugar cookies are perfect for St. Patrick's Day parties, cookie exchanges, or as thoughtful homemade gifts. Arrange them on a festive platter alongside other Irish-inspired treats, or package them individually in clear cellophane bags tied with green ribbon for party favors. They pair beautifully with a cup of Irish breakfast tea, coffee, or even a glass of cold milk. For a stunning dessert table centerpiece, stack the cookies on a tiered stand and surround them with fresh flowers or gold coins. Kids especially love decorating their own cookies, so consider setting up a decorating station with different shades of green icing, sprinkles, and edible glitter for a fun, interactive activity.
