I saw a recipe the other day that called for Bisquick, but I didn't have any. So I threw together the ingredients for homemade baking mix that can be used the same way. The advantages to making it at home are that you can control the salt and you can make it using whole wheat or even an all-purpose gluten-free flour.
VEGAN BAKING MIX
(store in refrigerator in a zipper baggie)
6 c. Flour (white, whole-wheat or gluten-free)
3 T. Baking Powder
2 1/2 t. Salt (optional)
1/2 c. Crisco OR Butter Crisco OR Coconut Oil (softened)
Mix all dry ingredients and then cut in the oil until well combined. Use as you would Bisquick in any recipe.
