https://www.powerhungry.com. She's got a grain free baking category.
I think the only grain free one of hers I've tried is the chickpea flax bread. It was tasty and had a pretty good texture. It was a little dry once it cooled, which I find is an issue with chickpea flour in general. I heated it up and ate it with peanut butter and
apple and the dryness was gone.
I've seen other recipes ofvhers using almond or sunflower, coconut, lentils. Lots of options.
The only warning I'd give is that if you're following her recipes using the weights, rather than the volumetric measurements, watch the amount of
water you add. It seems to end up being too much water when I've done it that way.
