Method
Preparation
Preheat the oven to 350°F (175°C).
In a large bowl, cream together brown sugar and butter until smooth.
Beat in the egg and maple syrup until well combined.
In another bowl, whisk together flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture until a dough forms.
Baking
Roll tablespoon-sized balls of dough and place them on a lined baking sheet.
Bake for 10-12 minutes, or until edges are lightly golden.
Let cool on the baking sheet for a few minutes before transferring to a wire rack.
Glazing
For the glaze, mix powdered sugar, maple syrup, and milk until smooth.
Drizzle the glaze over the cooled cookies and let set before serving.
Notes
Store cooled cookies in an airtight container at room temperature for up to 3 days. To keep glaze from sticking, put parchment paper between layers. For longer storage, freeze cookies for up to 2 months.
