Equipment

  • Kitchen Scales
  • Chopping Board
  • Knife
  • Mixing Bowl
  • Slow Cooker

Ingredients

Metric - US Customary
  • 1 tablespoon Butter for greasing
  • 6 Bramley Apples (roughly 1kg) peeled, cored and sliced
  • 50 g Caster Sugar
  • ½ teaspoon Cinnamon

For the crumble

  • 125 g Plain Flour
  • 125 g Porridge Oats not jumbo or quick cook oats
  • 125 g Light Brown Sugar
  • 125 g Unsalted Butter melted

Instructions

  • Place the flour, oats, and light brown sugar in a large bowl and pour over the melted butter. Mix until crumbles form.
    125 g Plain Flour, 125 g Porridge Oats, 125 g Light Brown Sugar, 125 g Unsalted Butter
  • Butter the slow cooker basin and place the thinly sliced apples, cinnamon, and caster sugar in it. Give it a good mix with a spoon.
    1 tablespoon Butter, 6 Bramley Apples, 50 g Caster Sugar, ½ teaspoon Cinnamon
  • Top the apples with the crumble topping and lightly press it down with the back of a spoon or your hand.
  • Put a tea towel under the lid then flip up the edges of the tea towel over the lid so they don't hang down over the slow cooker.
  • Slow cook on a high setting for 2.5 hours then remove the lid (and tea towel) and cook for a further 45 minutes to crisp up the crumble topping.

Notes

Expert Tips:
  • As there is no pre-cooking of the apples in this recipe, be sure to slice the apples as thinly as you can, so they cook evenly and become soft and tender. 
  • Instead of buttering the slow cooker basin you could spray it with a light cooking oil to save calories.
 
Variations:
  • Add 1 peeled and sliced pear to the recipe for an apple and pear crumble or fresh berries such as raspberries or blueberries.
  • Add a handful of chopped walnuts or pecans to the crumble topping for added crunch and texture.
  • Add a handful of dried cranberries or raisins to the apple filling for an extra fruity taste.
  • Add half a teaspoon of ground ginger to the apple filling for warmth and spice.
 
Storage:
Store - Leftovers can be stored in an airtight container in the fridge for up to 3 days.
Reheat - Reheat in the microwave until hot. Crumble can also be eaten at room temperature.
Freeze - The slow cooker apple crumble can be frozen for up to 3 months.
