Preheat your oven to 170 Fan / 190 C / 375 F / Gas 5 and line a 7 x 9 inch baking tray with parchment, covering the base and sides.
Put the ground flax seeds into a cup or mug and mix with 1/3 cup (80ml) cold water. Set aside.
Peel the bananas and break into chunks into a large bowl. Mash well with a fork or potato masher.
Add the chocolate spread, fudge brownie shake, syrup and vanilla and whisk together.
Whisk in the flax/water mixture.
Stir in the oats and baking powder and mix well.
Pour into your prepared tin and smooth to the corners.
Sprinkle the chocolate chips all across the top then gently push them into the mixture. You want them visible but slightly submerged so they don't all fall off once baked!
Bake for 40 minutes until set and lightly golden
Eat immediately or leave to cool before cutting into squares and storing in the fridge or freezer
Notes
Putting the cooled baked oats in the fridge to chill completely before slicing makes cutting them up much neater (if neatness is your thing!)
We don't have a microwave so I don't know if these are any good to warm up. Would love to know if anyone tries!
