For the fruit

6 large stalks rhubarb, washed and chopped

2­3 apples, chopped

100g raspberries, fresh or frozen

Juice of 1 lemon

6 tablespoons Natvia natural sweetener

2 tablespoons cornflour

Pinch of cinnamon

For the crumble topping

70g rolled oats

50g oat flour

50g ground almonds

30g Natvia natural sweetener

1 teaspoon cinnamon

60g solid coconut oil

Pinch of salt


  1. Preheat the oven to 170 degrees C and lightly grease a deep pie/ceramic dish.
  2. Toss the prepared fruit in the lemon juice, Natvia and cornflour ­ mix well then pour into the dish.
  3. Mix together the oats, oat flour, almonds, cinnamon, and Natvia in a bowl. Add the solid coconut oil then rub it into the dry ingredients to form a crumble. Add very small splashes of water and mix so little crumble clumps form.
  4. Sprinkle this all over the fruit to form a generous layer then bake in the oven for about 30 minutes until golden and bubbling. You may want to cover halfway through cooking with tin foil to prevent burning. Leave to cool a little then serve ­ or once cooled. Enjoy!
