Ingredients
 
 

  • 160 g Plain All Purpose Flour
  • 40 g Oats , rolled or porridge oats
  • 1 tsp Ground Cinnamon
  • 100 g Unsalted Butter
  • 160 g Light Brown Soft Sugar
  • 40 g Hazelnuts, Chopped
  • 1 tbsp Demerara Sugar

Instructions

  • Preheat the oven to 180C (356F)
  • Remove the butter from the fridge and chop it into small cubes. Place it back in the fridge while you prepare everything else.
  • Mix together the flour and cinnamon in a large bowl.
  • Add the cold, cubed butter to the flour and with clean fingers, rub the ingredients together to form a breadcrumb like texture.
  • Stir in the oats and soft brown sugar.
  • Chop the hazelnuts and mix in.
  • Line a baking tray and evenly spread the crumble mixture onto it.
  • Sprinkle over the demerara sugar.
  • Place the crumble mixture into the oven and bake for 20 minutes until golden brown.
  • Remove the tray from the oven and allow the mixture to cool slightly.
  • When your fruit base for the crumble is ready, evenly sprinkle the crunchy crumble topping over it and serve immediately.

Recipe Notes

 
  • Bake it separately for the most crunchy results. You can also bake it on top of a fruit base if you'd prefer but the result might not be the same. 
  • You can freeze the crumble mixture before baking for up to 3 months. 
  • Ensure the butter is cold. Using warm or softened butter will result in a texture difference and the crumble mixture will likely end up as a ball of dough instead of a crumbly texture.
