Any specific flour you want to use? I'd probably stick with an oat flour blend.
Try the Rories gluten free oat mix.
Thanks. That's what was recommended to me, so I went to the store on Friday to get it, but they were out. I saw something there instead called Blends by Orly - same idea as Rories. It was ok - my 4-year-old (the one who needs to like it...) had a piece on Friday when it was fresh out of the oven, but wouldn't have more than a bite Shabbos day (even though we warmed it up).
