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

In a bowl, whisk together flour, baking powder, salt, and cinnamon.

In a separate bowl, cream the softened butter with granulated and brown sugars until light and fluffy.

Beat in eggs one at a time followed by vanilla extract.

Gradually mix in dry ingredients until just combined.

Roll dough into balls or cut into heart shapes; place on prepared baking sheets.

Bake for 10-12 minutes until edges are golden but centers remain soft.
