Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a large mixing bowl, beat the softened butter and brown sugar together until light and fluffy.
Beat in the egg, maple syrup, and vanilla extract until well combined.
In another bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Use a cookie scoop or tablespoon to form dough balls and place them on the prepared baking sheet.
Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
