Delight with a sweet and tangy rhubarb crumble with oats
There is something instantly comforting about a rhubarb crumble. As it bakes, you can smell the warmth rising from the oven: buttery, fruity, and gently caramelised. This rhubarb crumble is sweet and tangy, with the unmistakable charm of a true classic. It has a humble, rustic look where nothing needs to be perfect because once you taste it, the flavour speaks for itself.
When the spoon digs in, the crumble topping crackles gently, revealing the soft, delicious rhubarb underneath. This is the kind of dessert that is made for relaxed family dinners or weekend brunches with friends, especially when you want things to end on a sweet note.
Tender and juicy rhubarb with vanilla and sugar
Once rhubarb goes into the oven, it quickly transforms. The firm pieces soften, turn tender, and release their tangy juices. Its striking pink-red colour hints at what is to come, and the aroma that fills the kitchen as it cooks is irresistible. When combined with vanilla and sugar, it does not get any better. Sweetness and tanginess are a match made in heaven, and a bit of cornflour ensures that the texture does not turn watery.
Topped with a crisp crumble mixture of oats, cold butter, and a bit of sugar
The crumble topping is where all the crunch comes from. With a little Lurpak® butter, the mixture stays light and crumbly. The butter melts slowly and creates tiny gaps and layers that give the topping its crisp, crunchy texture. Using cold butter is key, as it helps the crumble stay airy and pleasantly crisp instead of melting into a solid layer.
The oats toast gently in the oven, adding extra texture and bite, while the sugar melts and caramelises just enough to give the topping a golden colour and a subtle sweetness. This crunchy topping is the perfect contrast to the soft, juicy rhubarb underneath, making every spoonful more enjoyable than the last.
Savour it warm with a scoop of vanilla ice cream, custard, or crème fraiche
Rhubarb crumble is at its very best when served warm. The heat enhances the textures, keeping the rhubarb soft and the topping crisp.
Elevate the rhubarb crumble with a scoop of slowly melting vanilla ice cream, adding a cooling creaminess that balances the sweet and tangy flavours. Of course, if you want to evoke childhood nostalgia, best serve it with vanilla custard. It wraps the crumble in a velvety, scrumptious richness. And to set a fresh counterpoint, crème fraiche is perfect. It brings a gentle freshness and light acidity that complements the rhubarb like no other.

Experiment with your own variations
Put your mark on a classic and experiment with different flavours and textures. Enrich the recipe with a few spices. When preparing the rhubarb, try adding a small amount of ground cinnamon, ginger, or cardamom as you mix with sugar, vanilla seeds, and corn flour. A ¼ tsp of cinnamon or ginger should do the trick, but use cardamom sparingly because of its strong flavour.
For the crumble topping, try mixing spices into the oats, flour, and sugar before adding the butter. Cinnamon is a classic option, but ginger or a pinch of cardamom adds a more distinct and pronounced warm flavour. You can also add 30-50g of chopped nuts, for example, almonds, hazelnuts, pecans, or walnuts. This will give the topping extra crunch and a rich, nutty flavour that goes great with tart rhubarb. If you like more nuts, you can reduce the oats to 40-50 g to keep the crumbly texture. Make sure the nuts are chopped finely so they toast evenly and do not burn.
You can also add apple to the filling. Use a firm, slightly tart apple, peeled and cut into small pieces, and mix it with the rhubarb. The apple softens as it bakes, adding a mellow sweetness and balancing the tartness of the rhubarb.
