St. Patricks Shamrock Sugar (Printable Version)

Delightful shamrock sugar cookies decorated with smooth green royal icing for festive occasions.

# What You’ll Need:

→ Sugar Cookies

01 - 1 cup unsalted butter, softened
02 - 1 cup granulated sugar
03 - 1 large egg
04 - 1½ teaspoons pure vanilla extract
05 - ½ teaspoon almond extract
06 - 2¾ cups all-purpose flour
07 - ½ teaspoon baking powder
08 - ½ teaspoon salt

→ Royal Icing

09 - 3 cups powdered sugar, sifted
10 - 2 tablespoons meringue powder
11 - 4 to 5 tablespoons warm water
12 - ½ teaspoon pure vanilla extract
13 - Green gel food coloring

# Step-by-Step Guide:

01 - In a large bowl, beat softened butter and granulated sugar together with an electric mixer until light and fluffy, approximately 2 to 3 minutes.
02 - Add egg, vanilla extract, and almond extract to the creamed mixture. Beat until fully combined.
03 - In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to the butter mixture, mixing just until incorporated.
04 - Divide dough in half. Flatten each portion into a disc, wrap in plastic wrap, and refrigerate for at least 1 hour.
05 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
06 - On a floured surface, roll out one dough disc to ¼ inch thickness. Cut out shamrock shapes using a cookie cutter, spacing cookies 1 inch apart on prepared sheets.
07 - Bake for 8 to 10 minutes until edges are just beginning to turn golden. Cool on baking sheets for 5 minutes, then transfer to a cooling rack to cool completely.
08 - Combine powdered sugar, meringue powder, and vanilla in a bowl. Add water one tablespoon at a time, beating on low speed until stiff but pipeable peaks form. Tint with green gel food coloring.
09 - Transfer icing to a piping bag fitted with a small round tip. Outline and flood each cooled cookie with icing. Add details or sprinkles as desired. Allow icing to dry completely before serving or packaging.

# Additional Tips::

01 -
  • The dough is forgiving enough that even imperfect shamrock shapes taste incredible.
  • Royal icing transforms simple sugar cookies into gifts fancy enough to impress anyone.
  • They stay fresh for days, which means you can actually bake ahead instead of panicking last-minute.
02 -
  • Meringue powder is non-negotiable—without it your icing stays glossy but soft, and these cookies were made for that crisp, satisfying crack when you bite into them.
  • Cold dough rolls out easier and cuts cleaner, so if you're getting warm and frustrated, chill it again for 15 minutes instead of wrestling with it.
03 -
  • Keep meringue powder in a sealed container away from humidity, or it won't whip properly when you need it.
  • If your icing cracks while drying, it means you let it get too warm—a cool, dry spot with a little air circulation is ideal.
