Preheat your oven to 200°C/180°C(fan)/400°F/Gas 6.
In a large bowl, mash up 3 Bananas.
Add 300 g Oats and any other ingredients that you are using.
Mix well and form into cookie shapes. These won't change shape and spread when cooking, so the shape you put them on the tray is the shape they will stay. Put on a lined baking tray.
Put them into the oven for 12-15 minutes. Allow to fully cool before eating.
Notes
Why have 2 ingredients when you can have 3? Get creative an add in some chocolate chips, coconut or chopped nuts for different flavored cookies.
Allow to cool before eating.
These are a great way to get young kids involved in the kitchen. They can mash the bananas and stir in the oats.
You can also change these up by blending the oats to make a flour and mixing that with the banana. You could also use ground almonds instead of oats.
An ice cream scoop is the best thing to use to get the right amount of mixture for each cookie.
To ensure this recipe is definitely gluten free, use oats that are certified gluten free.
