Preheat your oven: Set it to 350°F (175°C) and line a baking sheet with parchment paper.
Cream the butter and sugar: In a large bowl, beat the butter and granulated sugar together on medium speed until light and fluffy, about 2-3 minutes.
Add maple syrup and egg: Mix in the maple syrup and the egg until fully incorporated.
Combine dry ingredients: In another bowl, whisk together flour, baking powder, salt, and cinnamon.
Mix dry and wet ingredients: Gradually add the flour mixture to the wet ingredients, mixing until just combined.
Chill the dough: If time permits, chill your dough for 15-30 minutes to enhance the flavors and make it easier to handle.
Shape the cookies: Using a tablespoon, scoop out the dough and roll it into balls. Roll each ball in a mixture of cinnamon and sugar.
Bake: Place the cookie balls on the prepared baking sheet and bake for 10-12 minutes, or until the edges are golden.
Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
