Start by preheating your over to 175 Celcius or 350 Farenheit.
Add the ripe bananas to a bowl and mash them. Now melt the coconut oil and chocolate and add it to the mashed banana. Add the remaining ingredients and mix until everything's combined.
Now place the mixture on a baking tray and press it together to create a big rectangle. Bake for 15 minutes on 175 and then turn the heat down to 125 Celcius or 250 Farenheit while breaking the big piece into chunks. Now bake it for another 30 minutes.
Once down remove the granola from the oven and let it cool down completely. Store it in a airtight container and enjoy!
