  • 1 cup (200 g) granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon almond extract (optional)

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.

Zusatztipps für die Zubereitung

Chilling the dough is essential for cleanly cut shamrock shapes and easier handling. Make sure to sift the powdered sugar for the royal icing to prevent any lumps and achieve the perfect glossy finish. Use a fine piping tip for detailed outlining before flooding the cookies.

Varianten und Anpassungen

If you prefer a nut-free version, simply omit the almond extract without compromising flavor. To add festive flair, consider sprinkling edible gold glitter or colorful sprinkles onto the wet icing. For softer cookies, shorten the baking time by one minute.

Recipe FAQs

What gives the cookies their buttery texture?

The use of softened unsalted butter creamed with sugar creates a tender, rich texture in the cookie dough, resulting in soft, buttery cookies after baking.

How is the vibrant green color achieved in the icing?

Green gel food coloring is mixed into the smooth royal icing to create the bright, festive green shade perfect for St Patricks Day decorations.

Why should the dough be chilled before baking?

Chilling the dough firms it up, making it easier to roll and cut clean shamrock shapes, and helps prevent spreading while baking to maintain crisp edges.

Can almond extract be omitted from the dough?

Yes, almond extract is optional and can be left out if preferred or due to nut allergies without affecting the overall texture greatly.

What is the purpose of meringue powder in the icing?

Meringue powder stabilizes the royal icing, helps it set firmly, and contributes to the smooth texture needed for detailed decorating.
