Process all crust ingredients in a food processor into a fine sticky crumble. Transfer into the oiled pan press down to shape into a crust with your hands along the base and sides of the pan (Tip: make sure you "seal" the gap in the base when shaping the crust -- i.e. don't leave cracks in the crust, so that the filling doesn't leak out anywhere while baking). Set aside.
Blend all filling ingredients into a smooth mixture in a power blender. Pour into the prepared crust and smooth out the top.
Bake in a preheated oven for 1 hour and 10 mins until the top is nice and golden. Remove and cool on a wire rack completely (a few hours or overnight is best)(note the top will sink a touch as it cools, which is normal). Remove from pan, slice and enjoy with a bit of coconut whip on the side. Store leftovers in the fridge. Enjoy!
