I made these yesterday. They are kind of crusty on the outside and chewy on the inside.

1/2 cup tapioca flour
3 TBS Coconut flour + 2 TBS Coconut flour
1/2 TBS garlic powder
1/2 salt
1/4 cup hot water
1 Large egg + 2 egg whites (whisked)
A few drops of liquid stevia- optional

Combine the 3 TBS of coconut flour with the other dry ingredients and stir together in a mixing bowl.
Add hot water and stir.
Add egg mixture and stir.
Add stevia- optional
Mix in the other 2 TBS of coconut flour.

Let it sit for a few minutes. Spoon out dough onto a greased cookie sheet. I made mine slightly flat and into 3 biscuits.

Bake at 360 and check around 15 minutes.
