- Preheat oven to 180 degrees Celsius.
Using a blender, grind about 5 cups of oats till flour like.
Peel and mash banana.
Mix a few spoons of oat flour into mash banana to make it into a dough.
On a lightly floured surface, pat the dough and knead them into bars or different shapes to your liking.
Spread out the bars evenly on your baking tray.
Bake it for about 15 minutes. (Bake the biscuits longer, if you want the biscuits to be harder.)
