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

# How To Make It:
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 if using 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. Cut out shamrock shapes using a cookie cutter and place cookies 1 inch apart on prepared baking sheets.
08 - Bake for 8 to 10 minutes, or until edges are just beginning to turn golden. Let cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
09 - Combine powdered sugar and meringue powder in a bowl. Add water and vanilla, then beat with an electric mixer on low speed until smooth and glossy, 5 to 7 minutes.
10 - Add green gel food coloring and mix until desired shade is reached.
11 - 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.
