Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.

In a large mixing bowl, cream together softened butter and granulated sugar until light and fluffy, about 5 minutes.

Add eggs one at a time, mixing well. Then add buttermilk, salt, vanilla extract, and maple extract; beat until smooth.

In a separate bowl, whisk together baking soda, baking powder, and flour. Gradually fold the dry ingredients into the wet mixture.

Drop rounded portions of dough onto prepared sheets, spacing 2 inches apart, and bake for 6-8 minutes until edges are set.

Transfer baked cookies to wire racks to cool completely.

In a saucepan, melt butter and brown sugar over medium heat. Stir in milk and maple syrup, bring to a gentle boil, then cool slightly before adding powdered sugar.

Ice the cooled cookies with the maple icing generously.
