Excellent in the morning or anytime of the day. Instead of butter I used olive oil and I also substituted sugar with agave sirup. You can always use just a whole-wheat flour.
350 gr flour (I used 50% of whole-wheat flour and 50% of normal flour)
50 gr agave sirup
80 gr olive oil
Apples (as many as you like)
Prepare a baking pan (over it with a baking sheet). Mix flour with agave sirup and oil and once you form a dough-like mixture, take 3/4 of it and cover the bottom of a baking pan with it.
Add a layer of shredded apples, I used 4 big apples.
Add a layer of raisins, I used 2 handfuls, press it into the apple layer.
Mix the remaining crumble mixture with flex seed (you can use also shredded coconut, sesame seeds, nuts etc).
Bake for 45 minutes on 180 C.
