Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, cinnamon, baking powder, and salt.
Gradually add the dry ingredients to the butter mixture, mixing until just combined. Be careful not to overmix.
Roll the dough into 1-inch balls and place them on the prepared baking sheet, spacing them about 2 inches apart.
Gently flatten each ball with the bottom of a glass or the palm of your hand.
Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
