Preheat your oven to 350°F (175°C).

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

In another large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the egg and vanilla extract to the butter mixture, mixing until well combined.

Gradually add the dry ingredients to the wet ingredients, stirring until just combined.

Using a cookie scoop, drop rounded tablespoons of dough onto a baking sheet lined with parchment paper.

Flatten each dough ball slightly with your fingers.

Bake in the preheated oven for 10-12 minutes until the edges are golden.

Remove from the oven and let the cookies cool on the baking sheet for 5 minutes.

Transfer the cookies to a wire rack to cool completely.
