Preheat oven and prep pan:
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Prepare dry ingredients:
In a bowl, whisk together the all-purpose flour and baking powder until well combined.

Cream butter and sugar:
In a separate bowl, cream the softened butter and granulated sugar together until light and fluffy (about 3 minutes).

Add eggs and vanilla:
Beat in the eggs one at a time, making sure each one is fully incorporated. Stir in the vanilla extract.

Color the dough:
Divide the dough into portions and add your desired gel food coloring to create the St. Patrick’s Day colors. Mix thoroughly until the color is evenly distributed.

Scoop and shape:
Scoop tablespoon-sized portions of dough and place them on the prepared baking sheet, leaving some space between each cookie. You can lightly press down on each cookie if you prefer a flatter shape.

Bake:
Bake for 10-12 minutes or until the edges of the cookies are lightly golden.

Cool and decorate:
Allow the cookies to cool on wire racks before decorating with sprinkles or additional icing if desired.
