01 - Preheat the oven to 350°F and line two baking sheets with parchment paper.
02 - Whisk together the flour, baking soda, and salt in a medium bowl and set aside.
03 - Using an electric mixer or wooden spoon, cream the softened butter and brown sugar together until light and fluffy, about 2 minutes.
04 - Beat in the maple syrup, egg, and vanilla extract until fully incorporated.
05 - Gradually add the dry ingredients to the wet mixture, stirring just until a soft dough forms.
06 - Scoop tablespoon-sized portions of dough and roll into balls. Arrange them 2 inches apart on the prepared baking sheets.
07 - Optionally, sprinkle each cookie with coarse sugar or maple sugar.
08 - Bake the cookies for 10 to 12 minutes, until the edges turn lightly golden.
09 - Allow cookies to cool on the baking sheet for 3 minutes before transferring to a wire rack to cool completely.
