Ingredients

For the crumble topping:

For the fruit filling:

  • 4 large Bramley/cooking apples around 800 g (1¾ lb) before peeling and coring
  • 75 g golden caster sugar
  • 1 tsp cinnamon optional

Instructions

  • Prepare the apples by coring, peeling and slicing, and place them in the slow cooker.
    4 large Bramley/cooking apples
  • Make the crumble in the usual way; sift the flour into a bowl, rub in the butter, stir in the sugar and oats. Add the cinnamon.
    200 g plain flour (all-purpose flour), 125 g butter, 100 g golden caster sugar, 70   g porridge oats, 1 tsp cinnamon
  • Tip in the sugar for the fruit over the chopped apple, and give it a stir. Spray the sides of the slow cooker bowl where the crumble will be with some cooking spray or oil, to prevent sticking. 
    75 g golden caster sugar
  • Finally, tip the crumble mixture over the fruit and press it down lightly.
  • Now switch the slow cooker on to high, place a clean tea towel under the lid to stop water dripping onto the crumble, and cook on high for 3 hours.
  • After two and a half hours, place the lid ajar and cook for another 30 mins to an hour until the crumble firms up and starts to go crispy around the edges.
    Serve and enjoy!
