Preheat your oven to 350°F (175°C).

In a large bowl, cream together the softened butter and brown sugar until the mixture is fluffy and light in color (about 2 minutes).

Stir in the maple syrup and egg until well incorporated.

In a separate bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients, stirring just until combined.

Using a tablespoon or cookie scoop, drop rounded balls of dough onto a prepared baking sheet, leaving space between each cookie.

Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown.
