Preheat oven to 200°C/375°F.
Peel bananas and mash them until smooth with a fork.
Mix in all wet ingredients and then dry until well combined. Add to a baking dish.
Bake for 30-35mins or until golden brown on top.
Wait to cool, cut into slices, and enjoy! I personally enjoy these most warmed up (in the microwave for about 30 seconds).
* Will store in the fridge for up to five days
* Chia seeds work in place of ground flax to make 2 chia eggs.
* A combination of oat flour (I like 100g) and oats (50g) gives a more cake-like texture to the flapjacks. I make my own oat flour by grinding up oats in a coffee grinder.
* Feel free to swap out the peanut butter for any other nut or seed butter.
* Add in spices if you want – cinnamon, ginger, nutmeg, ground cloves, etc.
