I found this recipe on pinterest. It was fast enough that I could throw them together Sabbath morning before church! Even my "I don't like bananas" kid liked them! Here's the recipe, with my notes for next time.
2-3 overripe bananas, mashed (I used 2 large bananas)
1 1/2 c rolled oats
1 c unsweetened applesauce
a large handful of dried cranberries (my girls said we need more next time)
cinnamon to taste, I added quite abit (I thought), and it needs more . . .
it also needs salt
drop in spoonfuls onto baking stone (or baking sheets, but you'd probably want to grease them, or use parchment paper, these almost stuck to my baking stones). Bake 35 min at 350 degrees.
