Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large bowl, whisk together flour, baking powder, and granulated sugar; set aside.

In another bowl, cream the butter and remaining sugar until light and fluffy.

Beat in eggs one at a time, then mix in vanilla extract.

Gradually combine dry ingredients with wet ingredients until just mixed.

Scoop tablespoon-sized dough onto prepared sheets, spacing apart. Bake for 10-12 minutes until edges are golden.

Cool completely before filling with frosting made from powdered sugar and milk.
