Begin by browning the butter on the stovetop. Allow it to cool for about 10 minutes before adding it to a mixing bowl with coconut sugar, maple syrup, eggs, and vanilla extract. Beat on high speed for 2-3 minutes.
In a separate bowl, combine all-purpose flour, baking powder, and salt. Add the dry ingredients to the wet mixture and mix until just combined. Avoid over-mixing.
Fold in the chopped pecans, cover the dough, and chill for 30 minutes.
Preheat the oven to 350°F and line a baking sheet with parchment paper. Using a cookie scoop, form dough balls, flatten them slightly with your palm, and place them on the baking sheet.
Bake for 10-12 minutes or until the cookies are slightly firm to the touch. For a chewy texture, slightly under-bake.
Allow the cookies to cool completely before frosting.
For the frosting, combine powdered sugar, maple syrup, and vanilla extract until smooth and thick.
Frost the cookies, top each with a pecan, and enjoy!
