Preheat an oven to 170*C.
Blend oats into oat flour and roughly ground the coconut flakes too. Crush only roughly as we want the coconu flake texture in the bars.
Add everything in a bowl and mix until it becomes crumbly but also slightly sticky.
In a tray press some of the crumb to make a bottom layer. Not too thick and not too thin.
Peel and cut the apples. On a medium heat. Cook the apples and add a splash of water to help start the cooking process. After a couple of minutes mix in the coconut sugar and lemon juice.
Simmer on low until softened. This shouldn't take longer then 10 mins. Once cooked set a side ready to add into the crumb layer.
Add the apple filling on to the bottom layer generously.
Get the rest of the crumble mixture and sprinkle on top until fully filled.
Bake for 20 mins or until beautifully golden on top .
Once completely cool, slice into squares and enjoy hot or cold. I love having these bars with piping hot custard! But these are also SO good the next day after being in the fridge.
