Raspberry Crumble Slices

If you haven't been out to fill your baskets with berries yet this summer, now is the final time to do so - you can make your own jam! Although you can of course use shop bought if you prefer so that you can dive straight in to make this delicious recipe. Our preference of filling has to be raspberry for a beautiful burst of deep red but feel free to use whatever you have to hand or prefer. Blueberries and strawberries are great alternatives and they too create a sweet and sticky centre to contrast nicely with the the crisp yet flaky exterior of these slices.

We like to pop a batch into some plastic pots to take on day trips or when visiting friends as a tasty afternoon treat. The Mini Mes enjoy making these themselves, they are great for tweens to bake, and they get great satisfaction from layering the ingredients nicely before popping them into the oven to turn golden.

Raspberry Crumble Slices


140g self raising flour
120g rolled oats
90g light brown sugar
120g butter
Raspberry jam


  • Preheat the oven to 180 degrees and line a baking tray approx 8" by 10" in size with foil. Grease the top of the foil also to prevent the slices from sticking later on
  • In a bowl, mix together the flour, oats and sugar then mix in the butter to form your crumble
  • Take 2/3 of the mixture and spread it evenly into the dish, compacting it slightly so it becomes more firm

  • Use the back of a spoon to spread over a generous amount of jam ensuring you leave a gap of approx 1cm minimum around the edge

  • Sprinkle over the remaining crumble mixture to cover the jam and push it down gently to keep it in place

  • Cook for 28-30 minutes until golden and remove from the oven
  • Leave to cool completely then carefully take it out of the tray and take off the foil 
  • Cut into slices 
  • Scoff!

- Use different flavour jams
- Drizzle icing or melted chocolate over the top for added sweetness
- If you don't have the size dish mentioned above then simply cut the foil to size, place it inside a larger tray and use the foil as a guide for the mixture
