This serious allergen free pancake&waffle mix makes a great base, not only for a variety of different pancakes but for other baking needs as well. The package has a recipe for coffee cake but I imagine you can use it for any other cake recipe as well!
Ingredients: Sweet Brown Rice Flour, Tapioca Flour, Arrowroot Flour, Rice Milk Powder, Cream of Tartar, Xanthan Gum, Baking Soda, Sea Salt, Ground Vanilla Bean.
The sweet brown rice makes the pancakes chewier than fluffy but I don't mind that. Judging from the color of the dry mix, there is a lot more tapioca and arrowroot flour than brown rice flour and make the pancakes taste more refined than a whole-grain pancake would taste.
Try adding more brown rice flour, buckwheat flour, coconut flour, sweet potatoes or anything else you can think of to add flavor and/or texture!
