Mash the bananas with a fork or blend them in a blender.
Add the oats, cinnamon, vanilla and grated apple, then mix well.
Let the mixture rest for a few minutes. Meanwhile, set the oven to 180°C and line a baking tray with parchment paper.
Add the cranberries and chopped nuts to the oat mixture and combine gently. If it’s too thick, add some apple juice or plant-based milk.
Using your hands, make equal sized balls, then press them between your palms. Place them on the prepared baking tray.
Bake in the oven for approx. 15 minutes until golden.
Serve the cookies at room temperature.
