Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper or silicone mats.
In a large bowl, cream together the butter and brown sugar until light and fluffy. Add eggs one at a time, mixing well after each. Stir in maple syrup and maple extract.
In a separate bowl, whisk together flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Drop spoonfuls of dough onto the prepared baking sheets, leaving space between each cookie.
Bake for 10-12 minutes, or until the edges are lightly golden. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
