I used 3/4 steel cut oats and 1/4 c flaxseed. I put those into the blender to grind them up. I also used applesauce instead of butter. I'm not sure how much applesauce I used, but I had to add more flour to get it to cookie dough consistency. My daughter was helping, so I adjusted it according to her taste. She wanted it sweeter, so I added more applesauce, then I would have to add more flour.
They came out chewy and muffin-like, but they taste great!
