# What You'll Need:

→ Sugar Cookies

01 - 2 1/2 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/4 teaspoon salt
04 - 3/4 cup unsalted butter, softened
05 - 1 cup granulated sugar
06 - 1 large egg
07 - 1 teaspoon vanilla extract
08 - 1/2 teaspoon almond extract

→ Green Royal Icing

09 - 2 cups powdered sugar, sifted
10 - 2 tablespoons meringue powder
11 - 3 to 4 tablespoons water, room temperature
12 - 1/2 teaspoon vanilla extract
13 - Green gel food coloring

# Step-by-Step Guide:

01 - In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
02 - In a large bowl, cream butter and sugar together with an electric mixer until light and fluffy, approximately 2 minutes.
03 - Beat in egg, vanilla extract, and almond extract until fully combined.
04 - Gradually add the dry ingredients to the wet ingredients, mixing just until the dough comes together.
05 - Divide the dough into two discs, wrap in plastic wrap, and refrigerate for at least 1 hour.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.
07 - On a lightly floured surface, roll out dough to 1/4-inch thickness.
08 - Cut out shamrock shapes using a cookie cutter. Place cookies 1 inch apart on prepared baking sheets.
09 - Bake for 8 to 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 - Combine powdered sugar and meringue powder in a bowl. Add water and vanilla extract, then beat with a mixer on low speed until smooth and glossy, 5 to 7 minutes.
11 - Add green gel food coloring and mix until desired shade is achieved.
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.

# Expert Tips:

01 -
  • The dough is forgiving enough that even imperfect shamrock shapes taste absolutely buttery and perfect.
  • Green royal icing transforms plain cookies into something that feels fancy without needing any actual decorating skills.
  • You can make the dough days ahead and decorate whenever you find a quiet moment with a cup of tea.
02 -
  • Don't skip chilling the dough, because warm dough spreads too much and your shamrock shapes lose their definition in the oven.
  • Sift your powdered sugar before mixing it into the icing, because lumps will clog your piping bag and destroy your patience halfway through decorating.
  • Green gel coloring is non-negotiable if you want vibrant green icing, because liquid food coloring thins the icing and produces muddy, pale colors that disappoint.
03 -
  • Make the dough up to 3 days ahead and keep it wrapped in the refrigerator, so you only need to roll, cut, and bake on the day you want fresh cookies.
  • If you find your baked cookies slightly too hard, reduce the baking time by 1 minute next time, because even 30 seconds can make the difference between crispy and chewy.
  • Edible glitter sprinkled on wet icing transforms plain green shamrocks into something that looks like it came from a fancy bakery, and nobody needs to know you got it online.
