Mix well and bake on a pre-heated oven at 200 for 25-30 mins.
Meantime, in a separate bowl add the crumble topping ingredients and mix well until everything is well coated by the coconut oil.
Take the baking dish out of the oven and give the pears a mix.
Add the crumble topping and return to the oven for further 30 minutes. In this time I opened the oven a couple of time to give the topping a mix so the crumble cooks evenly.
