In a stand mixer fitted with the paddle attachment or with hand mixer and large bowl cream together the softened butter and brown sugar until fluffy. About 1-2 minutes.
Add the egg and beat until well incorporated.
Add the maple syrup and maple extract and beat together until fully combined. Scrape the sides of the bowl as needed.
Add the dry ingredients: baking soda, baking powder, salt and all purpose flour. Mix on low speed just until combined and no more white streaks remain.
Cover and chill the dough for 15 minutes.
While the dough is chilling, preheat the oven to 350°F and line 2 cookie sheets with parchment paper or lightly grease them.
Using a 2 tablespoon cookie scoop, or 2 level tablespoons, place cookie dough scoops 2 inches apart on prepared cookie sheets.
Bake cookies on center rack for 10-12 minutes until edges are lightly golden brown and centers are set.
Let cool 5 minutes on pan and then remove to wire rack to cool completely.
Once cookies are cooled, make the icing. In a microwave safe small bowl, melt the butter and maple syrup together. Whisk in the powdered sugar and tiny pinch of salt.
Use the whisk, a spoon, or piping bag and drizzle the glaze over the cookies. You could also frost or dip the tops of the cookies if you like that better.
Let cookies rest until icing has set. About 30 minutes.
Serve and enjoy!
