Method
Step 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.
Step 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.
Step 3:
Press the oaty mixture into the base of the pan until even.
Step 4:
Toss the rhubarb with the sugar and extract and sprinkle evenly over the oaty mixture.
Step 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.
Step 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.
Step 7:
Melt the white chocolate and either pipe or drizzle all over the top of the crumble topping.
Step 8:
Cool before refrigerating, cut into slices before serving.

Recipe Reviews
Delicious. I used half the amount of sugar, I also used soft light brown. I did three quarters with rhubarb and the other with strawberries, as one person doesn’t eat rhubarb. It was enjoyed by all the family. Would make again.
This is a fantastic recipe and have done it over a dozen times, often used a bag of frozen mixed fruits (defrosted and drained) in place of the rhubarb, equally delish. I live in Cyprus and on my 7th attempt at growing rhubarb, finally managed it and got 800g only this morning. Looks like I'll be baking two portions this afternoon with my own rhubarb this time 👍👍
It's our favourite dish for rhubarb, always a winner and we save a bit of time by using a food processor for the mixing bit. Quite forgiving as well as we sometimes "adjust" quantities of ingredients depending on what we have in the cupboard. Oh, also works with coconut oil instead of butter
Didn't have chocolate for the top but I don't think it needs it. So delicious!
Delicious, I didn't have enough rhubarb so made up the weight with strawberries, only added 80g of sugar to base 50g to Rhubarb and 50g to topping, still plenty sweet enough.
Lovely - had searched all my books for a rhubarb slice recipe, and then found this one.
I ran out of sugar, but think there's maybe a bit too much in the instructions. Had it hot with yoghurt.
