1. In a large mixing bowl, cream together the butter and sugar until light and fluffy.

2. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

3. In a separate bowl, combine the baking powder and flour. Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms.

4. Add a few drops of green food coloring to the dough, adjusting until desired color is reached. Mix until the color is evenly distributed.

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

6. Roll the dough into small balls and place them on the baking sheet. Flatten each ball with the bottom of a glass dipped in sugar.

7. Decorate the cookies with sprinkles, gently pressing them into the dough.

8. Bake for 8-10 minutes or until the edges are lightly golden. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
