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

In a large bowl, cream together softened butter, granulated sugar, and brown sugar until fluffy (about 3-4 minutes).

Beat in the eggs one at a time, followed by the vanilla extract until well combined.

In another bowl, whisk together flour, baking powder, cinnamon, and salt; gradually add to wet mixture until just combined.

Scoop dough onto prepared sheets about two inches apart and bake for 10-12 minutes until edges are golden brown but centers remain soft.

Let cool on the baking sheet for five minutes before transferring to wire racks.
