Like classic fruit crumble but in a cuttable, transportable bar, these delicious crumble squares are perfect for a summer picnic.



  • Cooking apples 2, (about 550-600g whole weight) peeled, cored & diced
  • Blackberries 150g
  • Granulated sugar 2-3 tbsp, adjust to taste
  • Water 100ml
  • Butter 200g, softened
  • Light brown sugar 200g
  • Self raising flour 200g
  • Bicarbonate of soda 1tsp
  • Porridge oats 150g
  • 20×30 cm tin about 2cm deep, greased & lined with baking paper


  • Step 1

    Preheat the oven to 200°C/180°C fan/gas 6.

  • Step 2

    Add the apple, blackberries, sugar and water to a medium pan. Cover and simmer gently until soft – about 8-10 minutes. Set aside.

  • Step 3

    Whizz together the butter and sugar in a food processor until creamed, then add the flour and bicarbonate of soda and pulse until combined; the mixture will be quite crumbly.

  • Step 4

    Lastly, add the oats and pulse again until mixed. Tip about two thirds of the crumble mix into the prepared tin and press down well with the back of a spoon. Spread the fruit all over the base evenly.

  • Step 5

    Sprinkle over the remaining crumble mixture then bake for 25 minutes until the top is crisp and golden.

  • Step 6

    Remove from the oven and allow to cool completely in the tin before cutting into squares.
