I used a mix of gf-oat flour and quinoa flour. I also added a scoop or so of protein powder. I tossed a handful of dairy free chocolate chips on the top, but didn't have enough to cover it all.
It has no xanthan gum so I was worried about how crumbly it would be, but it's good. Like most GF products, you need to make sure it's cooled 100%.
Corwyn liked it, once I convinced him it wasn't hot anymore. Nathan fell asleep at 6:10 and so will need to wait until the morning for his try.
