Begin by preheating your oven to 180 degrees.

Next, add your diced apple, lemon juice, caster sugar, water and corn flour all into a small saucepan and cook with a lid on medium low heat until only just  tender (10 mins roughly). Remove from heat, then stir through your berries and place in  a medium sized baking dish.

For the simple crumble, blend coconut oil, flour, baking powder and sugar quickly until you achieve a sandy texture. Then pour into a bowl and combine in the oats. Crumble this mixture on-top of the fruit, then bake in your oven for 30-40 minutes, or until golden and crisp on top.

Serve this comforting dessert with your choice of ice cream for the ultimate home dessert experience.
