Cut this crumble cake into bars to eat on the go or serve as a warming dessert with custard or ice cream!
Preheat the oven to 190C, place a baking tray in the oven and grease a cake tin with coconut oil. Sift the flour and cinnamon into a mixing bowl, add the butter and using your hands run it into the flour to form breadcrumbs. Scoop out 175g of the crumble mixture and place in a separate bowl.
Beat the eggs in a jug, stir the caster sugar and eggs into the large amount of crumble and press the mixture into the base of the greased cake tin. Place the apples and berries on top.
Mix the chopped nuts and coconut sugar into the crumble mixture and spoon on top of the fruit. Press down and place in the oven for 45 minutes or until golden brown. If the top begins to brown too quickly, carefully cover with foil.
