  • 5 Granny Smith apples, peeled, cored, and each cut into 8 wedges
  • 1 tsp ground cinnamon
  • 1 orange, zested and half juiced
  • 60g rolled oats
  • 50g walnut pieces
  • ½ tsp ground ginger
  • 75g plain flour
  • 85g light muscovado sugar
  • 90g unsalted butter, melted


  1. Put the slices of apple in a slow cooker.
  2. Sprinkle over the ground cinnamon, orange zest, and 1 tbsp juice and mix together.
  3. Put the oats and walnuts into a food processor and pulse a few times to give the texture of very coarse breadcrumbs. Pour into a bowl.
  4. Stir the ginger, flour, and sugar into the oat and walnut mixture, then add the butter and mix well.
  5. Spoon the crumble mix over the apples, covering them all. Lay two sheets of kitchen paper or roll them on top of the crumble.
  6. Cover with the slow cooker lid and cook on low heat for 3½ hrs.
  7. Remove the kitchen paper and cook for the last 10 mins with the lid just slightly ajar.

Tip: Laying a kitchen roll on top of the crumble helps prevent condensation from dripping back onto the crumble, giving you a more crisp crust.
