  • 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
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon almond extract (optional)
  • For the Green Royal Icing
  • 2 cups (240 g) powdered sugar, sifted
  • 2 tablespoons meringue powder
  • 3–4 tablespoons water, room temperature
  • 1/2 teaspoon vanilla extract
  • Green gel food coloring

Instructions

1. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
2. In a large bowl, cream butter and sugar together with a mixer until light and fluffy, about 2 minutes.
3. Beat in egg, vanilla extract, and almond extract (if using) until combined.
4. Gradually add the dry ingredients to the wet ingredients, mixing just until the dough comes together.
5. Divide the dough into two discs, wrap in plastic wrap, and refrigerate for at least 1 hour.
6. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
7. On a lightly floured surface, roll out dough to 1/4-inch (6 mm) thickness.
8. Cut out shamrock shapes using a cookie cutter. Place cookies 1 inch apart on prepared sheets.
9. Bake for 8–10 minutes, or until edges are just beginning to golden. Let cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
10. For the royal icing, combine powdered sugar and meringue powder in a bowl. Add water and vanilla, then beat with a mixer on low until smooth and glossy, 5–7 minutes.
11. Add green gel food coloring and mix until you reach the desired shade.
12. Transfer icing to a piping bag fitted with a small round tip. Outline and flood the cooled cookies. Allow icing to set for at least 1 hour before serving.

Zusatztipps für die Zubereitung

To ensure the cookies keep their shape while baking, chill the dough thoroughly before rolling and cutting. Rolling the dough evenly to 1/4 inch thickness helps the shamrocks bake uniformly. Use a light touch when adding dry ingredients to avoid overmixing, which can make cookies tough. Allow the royal icing to fully set for a smooth finish and to avoid smudging.

Common Questions

What makes the cookies tender and buttery?

The combination of softened unsalted butter and sugar creamed together creates a tender crumb and rich buttery flavor in the dough.

How do I achieve the vibrant green color on the icing?

Adding green gel food coloring to the royal icing mixture gives the icing a bright and festive green hue without affecting consistency.

Why is chilling the dough important before baking?

Chilling firms the dough for easier rolling and cutting, and helps the cookies hold their shape during baking.

Can the almond extract be omitted safely?

Yes, the almond extract is optional and can be left out without compromising the overall flavor profile significantly.

How long should the icing set before handling?

Allow the royal icing to dry and set for at least one hour to achieve a firm, glossy finish that holds its shape.

What tools are essential for decorating?

A piping bag fitted with a small round tip is ideal for outlining and flooding the cookies with royal icing for smooth decoration.
