Preheat oven to 350º F and line a baking sheet with parchment paper.
Stir together butter, coconut sugar, aquafaba and vanilla in a large bowl until well combined.
In another bowl, combine oat flour, cinnamon, baking powder, baking soda and salt.
Pour flour mixture into butter mixture and stir to combine.
Stir in oats.
Fold in coconut and pecans.
Use a cookie scoop (I used a #30 disher) or your hands to create dough balls. Press down on each dough ball lightly with your fingertips. If you don't have a large enough baking sheet, you can bake in two different batches. You want to make sure the dough balls are not too close so that they don't run into each other.
Bake approximately 12-16 minutes until cookies are set and edges appear light golden brown (mine took 15 minutes).
Cool on baking sheet for approximately 5 minutes before transferring to wire rack to continue to cool.
