  • 3 tbsp plain flour
  • 3 tbsp rolled oats (jumbo oats)
  • 3 tbsp coconut sugar
  • ½ tsp ground cinnamon
  • 25 g melted unsalted butter
  • 100 g baking apples, cubed (see notes)
  • 250 g fresh berries (I used strawberries, blueberries + raspberries)
  • 1 tsp arrowroot powder
  • 2 tbsp unpasteurised honey
  • 1 tsp pure vanilla extract
  • 1 tsp lemon juice


  1. Preheat the oven to 180ºC (350ºF) and lightly grease a small 16 x 10 cm (6 x 4 inch) baking dish with oil or butter.
  2. To make the crumble, whisk together the flour, oats, coconut sugar, and cinnamon in a small bowl using a fork. Pour over the melted butter and toss with the fork until all the mixture is coated and resembles wet, clumpy sand. Set aside.
  3. In a large bowl, toss together the apples, berries, arrowroot powder, honey, vanilla, and lemon juice until well coated.
  4. Scrape the fruit mixture into the prepared baking dish. Top with the crumble mixture.
  5. Place the dish on a baking tray and bake for 30-35 minutes, or until bubbly and golden and the apples are softened. At the 20-minute mark, check the crumble and cover loosely with a layer of foil if it looks too browned.

  6. Remove the crumbles from the oven and allow them to rest for 5-10 minutes. Serve warm with vanilla ice cream, yoghurt, or whipped cream.


  • Make sure your apple chunks aren’t larger than 1.5 cm (½ inch). No need to peel! Just give them a good wash.
  • If your berries are very sweet, you can reduce the honey in the filling or leave it out completely to suit your taste.
  • These crumbles are best eaten on the day they are made.
