I used regular flour instead of oat flour, and tahini. I also added some whole oats and mini chocolate chips. I made them into mini muffins. They were ok with butter on top. Nice even without any sweetness.
It turned out ok. I halved the recipe and used thin strip steak cuts. Notes to self: I didn't have evaporated milk, and just used bullion cubes for the broth. Next time, use stock and thicken the gravy more.
