Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

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

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

Using a cookie scoop, drop spoonfuls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

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

Roll each cookie ball in the cinnamon sugar mixture to coat.

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

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
