Peel, cube, and cook the sweet potatoes until tender.
Preheat the oven to 350 degrees.
Mix all ingredient in a medium size bowl. Use a fork to mash everything together until evenly mixed and until all large pieces of fish and sweet potato are mashed up.
Add a little extra coconut flour if needed to get a dough that's roughly the consistency of play dough.
Roll into 1 inch balls and mash down with a fork to form little "cookies." I used my fingers on some to make a paw print shape.
Bake for 20 minutes or until lightly browned.
Remove from heat and let cool completely.
