Here's the website they originate from. And here's their recipe:
2 large, old bananas
1 cup oats
Then they suggest whatever mix-ins you want to throw in there - chocolate chips, coconut, cinnamon, whatever.
I obviously used chocolate chips. I also threw in some peanut butter, which is what I've seen suggested on other variations of this.
Grease the cookie sheet, bake at 350* for 15 minutes.
Verdict: Keeper. They're gluten-free, healthy (kinda, but you know what I mean), tasty and filling.
