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

In a medium bowl, sift together the dry ingredients: flour, baking powder, salt, and ground cinnamon. Set aside.

In a large bowl, use a mixer to cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3 minutes.

Beat in the eggs one at a time and then mix in the vanilla extract until smooth.

Gradually add the dry flour mixture to the wet ingredients, mixing until just combined.

In a small bowl, combine the granulated sugar and ground cinnamon for the coating.

Using a cookie scoop or tablespoon, scoop the dough and roll into balls. Roll each ball in the cinnamon sugar mixture.

Place the dough balls about 2 inches apart on the prepared baking sheets.

Bake for 10–12 minutes, until the edges are set and the centers look slightly soft.

Immediately after removing the cookies from the oven, roll them again in the cinnamon sugar mixture.

Transfer the cookies to a wire rack to cool completely.
