Gluten free?

Today I am looking for thoughts on gluten free recipes. I made "skinny" peanut butter chocolate brownies at work (which have no flour, butter or oil) but one of our regulars pointed out to me that they could be gluten free had I used steel cut oats instead of old fashioned rolled oats (which are rolled in flour to keep them separated and non clumping). She generously also offered to bring me almond flour and coconut flour to test out with some I my recipes and see how they turned out. So I'm looking to you, my faithful audience, for recipes you'd like me to try and make gluten free!
