Tired of gluten-free foods that have next to no nutritional value? So are we. The first grain in our chocolate cake mix is teff. Teff is one of the smallest grains in the world. But don't let the size fool you - this little powerhouse delivers protein, fiber, calcium, amino acids and iron. Some consider it a superfood. Then comes healthy oat flour. Throw in a little flax and tapioca, mix everything together and you get one amazing, moist, perfect chocolate cake (or cupcakes!).
