Don't want a whole crumble? Try this delicious crumble slice with tangy rhubarb and a crunchy oat base, perfect for afternoon tea.


  1. Preheat the oven to 180°C (fan 160°C, gas mark 4). Grease and line a shallow 20cm x 30cm tin with baking parchment.

  2. Sift the flour into the bowl, add the sugar and butter and rub together until it starts to come together, use a food processor if desired. Mix through the oats with clean hands to combine.

    • 180g Self-Raising White Flour (We use Allinson)
    • 110g Unrefined Golden Caster Sugar (We love Billington's)
    • 180g Salted Butter
    • 250g Porridge Oats
  3. Press the oaty mixture into the base of the pan until even.

  4. Toss the rhubarb with the sugar and extract and sprinkle evenly over the oaty mixture.

    • 400g Rhubarb (Trimmed & Chopped to 3cm Lengths)
    • 150g Unrefined Golden Caster Sugar (We love Billington's)
    • 1 tsp Vanilla Extract (We Like Nielsen Massey)
  5. For the topping add the sugar, flour and butter to a bowl and use your fingers to blend to form clumps that range in sizes. Stir through the flaked almonds.

    • 110g Unrefined Demerara Sugar (We love Billington's)
    • 80g Plain White Flour (We like Allinson)
    • 75g Salted Butter (Room Temperature)
    • 50g Almonds (Flaked)
  6. Sprinkle the topping over the rhubarb and bake in the preheated oven for 30 minutes or until golden. Let it cool in the tin.

  7. Melt the white chocolate and either pipe or drizzle all over the top of the crumble topping.

    • 40g White Chocolate
  8. Cool before refrigerating, cut into slices before serving.

    These are fabulous, and I have never liked rhubarb! A recipe that's easy to make and was enjoyed by all.

  2. 5 star rating

    I hadn't got any rhubarb, so i looked in my cupboard and found a tin of cherry pie filling. I will definitely be making this again, so versatile that any fruit you fancy would go.. Slices are really big, so you might need to cut them in half for little people! Definitely recommend, so quick and easy.

  3. 5 star rating

    Rhubarb being very plentiful, I'm always on the lookout for different ways to use it. This was super easy and absolutely delicious. My friends loved it too.
