Ingredients

• For the Sugar Cookies: 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)
• For the Royal Icing: 3 cups (360 g) powdered sugar sifted, 2 large egg whites or 4 tablespoons meringue powder plus 6 tablespoons water, 1/2 teaspoon vanilla extract or lemon juice, green gel food coloring
• For Decorating: 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 cookies

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 cookies

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: Prepare 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: Color the icing

Divide icing into bowls and tint with green gel food coloring as desired.

Step 11: Decorate cookies

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; stir before using to restore consistency. The almond extract adds a subtle, bakery-style flavor that complements the vanilla beautifully, but it can be omitted if you have nut allergies or prefer a simpler flavor profile. When working with royal icing, start with a thicker consistency for outlining the edges of your shamrocks, then thin the icing slightly with a few drops of water to create a flooding consistency that spreads smoothly within the outlines. Allow the outline to set for a few minutes before flooding to prevent colors from bleeding together.

Varianten und Anpassungen

While classic green shamrocks are traditional for St. Patrick's Day, you can customize these cookies in many creative ways. Try using different shades of green icing to create ombre effects or add white icing details for contrast. For a vegan version, substitute a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) for the egg in the cookie dough and use a vegan royal icing recipe made with aquafaba instead of egg whites. You can also experiment with different cookie cutter shapes if shamrocks aren't available—try hearts, circles, or four-leaf clovers. For extra flavor, consider adding a pinch of lemon zest to the dough or using lemon juice instead of vanilla in the royal icing for a bright, citrusy note.

Serviervorschläge

These shamrock sugar cookies are perfect for serving at St. Patrick's Day parties alongside other festive treats like green velvet cupcakes or mint chocolate desserts. Arrange them on a tiered serving platter for an eye-catching display, or package them individually in clear cellophane bags tied with green ribbon for party favors or gifts. They pair beautifully with hot beverages like Irish breakfast tea, coffee, or hot chocolate. For a more elaborate dessert spread, serve them with vanilla ice cream or alongside a bowl of fresh berries. The cookies also make wonderful additions to cookie exchange events or bake sales, as their professional appearance and delicious taste are sure to impress.
