I use this brand of oat flour
, but feel free to make our own oat flour by running your gluten-free oats through the food processor or dry container of your Vitamix
until it reaches flour consistency. I have not made these cookies using coconut sugar versus white sugar and brown sugar yet, but it should work fine. If you want a flatter, larger cookie, chill your dough a few minutes less. Store cookies in a sealed container to prevent cookies from drying out.
