Ingredients

Scale
  • 2 ¾ cups (344g) all-purpose flour (spooned and leveled)
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 2 tsp cornstarch
  • 1 cup (226g) unsalted butter, softened
  • 1 ¼ cups (250g) granulated sugar
  • 1 large egg, room temperature
  • 1 tsp pure vanilla extract
  • 2 tbsp whole milk (or plant-based milk if dairy-free)
  • For the Green Frosting:
  • 1 cup (120g) powdered sugar, sifted
  • 2 tbsp unsalted butter, softened
  • 1 tbsp whole milk
  • ½ tsp pure vanilla extract
  • Green gel food coloring (a few drops)
  • Optional: pinch of lemon zest

Instructions

  1. In a medium bowl, whisk together 2 ¾ cups (344g) flour, 1 tsp baking powder, ½ tsp baking soda, ½ tsp salt, and 2 tsp cornstarch. Set aside.
  2. In a large mixing bowl, beat 1 cup (226g) softened butter with 1 ¼ cups (250g) granulated sugar using an electric mixer on medium speed until pale and fluffy, about 3-4 minutes.
  3. Beat in 1 large egg, 1 tsp vanilla extract, and 2 tbsp whole milk until fully combined.
  4. Gradually add the dry ingredient mix to the wet ingredients, mixing on low speed until just combined. Avoid overmixing.
  5. Cover the dough with plastic wrap and refrigerate for at least 30 minutes.
  6. On a lightly floured surface, roll the dough out to about ¼ inch (6mm) thickness. Use shamrock cookie cutters to cut shapes, placing them about 1 inch apart on lined baking sheets. If dough softens, chill for 10-15 minutes.
  7. Preheat oven to 350°F (175°C). Bake cookies for 8-10 minutes until edges are set but centers remain soft.
  8. Transfer cookies to a cooling rack to cool completely before frosting.
  9. In a small bowl, beat 1 cup (120g) powdered sugar, 2 tbsp softened butter, 1 tbsp milk, ½ tsp vanilla, and green gel food coloring until smooth and creamy. Add lemon zest if desired.
  10. Spread frosting evenly on cooled cookies using an offset spatula or butter knife. Decorate with green sprinkles or edible glitter if desired. Let frosting set for about 15 minutes before serving.

Notes

Do not overbake cookies; edges should be set but centers soft. Chilling dough is essential to prevent spreading and maintain shape. Use gel food coloring for vibrant frosting without thinning. For gluten-free, substitute flour with gluten-free blend and add xanthan gum. For dairy-free, use vegan butter and plant-based milk.
