Mix coconut flour, cashew flour and agave powder in a large mixing bowl.
Add honey, water, vanilla extract, salt and scraped vanilla bean.
Use a wooden spoon or hands to form mixture into a dough.
Dough will start to form (add water if dough is too dry).
Scoop about 2 tablespoons of dough onto a sheet tray lined with parchment paper. (Slightly flatten dough with your palm).
Dehydrate macaroons 140F (60C) overnight. (The wetter the dough, the longer the macaroons will need to dehydrate).
