Anyone have experience baking bread using oat flour? I have a kid with serious IBS issues, so no wheat, no eggs and limited spelt. There's one brand we can buy at the local health food store that fits the bill - which they can eat as much of as they want. All the recipes I've found so far either require egg, or mixing in a bit of spelt.
