Apple Filling

  • 6 Green apples
  • 1 1/3 cup apple sauce 370gm
  • 1/2 tsp lemon zest
  • 1 tsp cinnamon




  • Line a baking tray with paper.
  • Remove the butter from the fridge to soften.
  • Preheat oven to 350F (180C).

  • Place the base mixture into the baking tray and press the dough down to form an even layer.

Apple Filling

  • Peel and core the apples. Roughly dice the apple into 1 1/2cm cubes.
  • Add the apples lemon zest, cinnamon and apple sauce to a large bowl. Stir to combine.

Crumble Layer

  • Spread the apple mixture over the base of the slice.
  • Using fingers add the crumble in clumps to the top of the apple layer. You want to squeeze bits together so the mixture isn't too small and crumbly on the top.
