Gluten Free Biscuits

There are other GF biscuit recipes out there that use rice flour and are really good; however, I can't have rice so this recipe uses other flours.

Ingredients: 
1/2 c sorghum flour
1/2 c coconut flour
1/2 c arrowroot or tapioca starch
1/4 c millet flour
1 t xanthan gum
1 T baking powder
1 t baking soda
1 packet Truvia
1/2 t salt
6 T cold vegan butter
1 c plain coconut yogurt

Directions:
Preheat oven to 425 degrees F.
Whisk together all dry ingredients in a bowl.
Cut up butter into cubes and add to dry ingredients. With a fork or a pastry cutter, blend butter into dry ingredients until mixture is crumbly.
Add yogurt to misture and stir until all combined.
Dump ball of dough onto parchment paper or a silicone mat and flatten out to 3/4" thick. 
Using a biscuit cutter or an open ended soup can, cut biscuits.
Place on a baking stone or cookie sheet, sides touching.
Bake for 15-20 minutes or until golden brown.
Remove from oven and serve.
