Preheat your oven to 350°F (175°C) and prepare two baking sheets by lining them with parchment paper.
In a large mixing bowl, cream together the softened butter and brown sugar until the mixture becomes light and fluffy.
Add the eggs one at a time, thoroughly mixing after each addition before stirring in the maple syrup.
In another bowl, whisk together the all-purpose flour, baking powder, cinnamon, and salt until well combined. Gradually incorporate this dry mixture into your wet ingredients until just combined.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto prepared baking sheets about two inches apart from each other. Bake them in the preheated oven for 10-12 minutes or until the edges turn lightly golden while keeping a soft center.
Once baked, allow the cookies to cool on the baking sheets for five minutes before transferring them to wire racks to cool completely.
