1 Cup White (Sweet) Rice Flour
1 Cup Almond Flour
¾ Cup Tapioca Starch
¾ Cup Potato Starch
1 Cup gluten-free Sweet Buttermilk Powder (be sure to read the label to avoid things like modified food starch, etc.)
¼ Cup gluten-free Baking Powder
¼ Cup Ener-G Foods brand Rice Polish (Can use ½ cup if you prefer really high-fiber)
¼ Cup Xanthan Gum
This is a great mix for muffins. You might want to try my Pumpkin-Raisin Spice Muffins.
