In a large bowl, mash the bananas. Then stir together with the coconut oil and vanilla.
Stir in all the remaining ingredients to evenly coat everything with the banana mix.
Pour the mix on to two baking trays, making sure to flatten any thick sections to allow for even cooking.
Bake for 20 minutes, then turn lightly, and bake a further 10-15 minutes until golden.
Allow to cool fully on the tray (it will crisp as it cools and this allows for goods clusters to form*).
Enjoy as snacks or with plant milk.
Storage
Store leftovers in an airtight container in the cupboard for up to 5 days, or freeze for up to 2 months.
Notes
This is for 18+ months due to the crunchy texture. However make sure to break up clusters before serving to toddlers under the age of 3. And ensure any nuts are finely chopped before adding to the mix.
