# Components:

→ Sugar Cookies

01 - 2.5 cups all-purpose flour

03 - 0.25 teaspoon salt
04 - 0.75 cup unsalted butter, softened
05 - 1 cup granulated sugar

11 - 0.5 teaspoon vanilla extract or lemon juice
12 - Green gel food coloring

→ Decorating

13 - Sprinkles or edible glitter

# Method:

01 - Whisk together flour, baking powder, and salt in a medium bowl. Set aside.
02 - Beat butter and sugar in a large bowl until light and fluffy, approximately 2 to 3 minutes.
03 - Add egg, vanilla extract, and almond extract to the butter mixture. Mix until fully combined.
04 - Gradually add dry ingredients to wet ingredients, mixing just until incorporated. Do not overmix.
05 - Divide dough in half, shape each portion into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.
07 - Roll dough on a lightly floured surface to 0.25 inch thickness. Cut shamrock shapes using a shamrock-shaped cutter and place on prepared baking sheets.
08 - Bake for 9 to 11 minutes until edges begin to turn golden. Cool on baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
09 - Beat powdered sugar, egg whites or meringue powder mixture, and vanilla or lemon juice in a large bowl until stiff peaks form and icing is glossy, approximately 5 minutes.
10 - Divide icing into bowls and tint with green gel food coloring to desired shade.
11 - Transfer icing to piping bags fitted with small round tips. Outline and flood cooled cookies. Add sprinkles or glitter if desired. Allow icing to set for at least 1 hour before serving.

# Expert Advice:

01 -
  • The dough is forgiving and actually fun to work with, especially if you've never cut shaped cookies before.
  • Royal icing sounds intimidating but it's honestly just a few ingredients beaten together until magic happens.
  • These keep for days in an airtight container, which means you can bake ahead and stress less during party prep.
02 -
  • Cooling the cookies completely before icing is non-negotiable—icing on warm cookies will slide right off and create a sad, melty mess.
  • If your royal icing looks too thick to spread, add water one drop at a time; if it's too thin, add more powdered sugar, because there's a sweet spot between outline and flood consistency.
03 -
  • If your dough is too soft when you roll it out, pop it back in the fridge for 15 minutes—your patience pays off with clean, sharp shamrock shapes.
  • Transfer the cooled cookies to a wire rack instead of leaving them on the baking sheet, because trapped steam on the bottom can make them slightly soft where you don't want it.
