Introduction to Rhubarb Apple Crumble
Rhubarb Apple Crumble is a timeless dessert that brings together the tartness of rhubarb and the sweetness of apples, all enveloped in a buttery, crunchy crumble topping. This dessert, a staple in many households, is cherished for its balance of flavors and textures. Whether served warm with a scoop of vanilla ice cream or a drizzle of custard, this crumble is a comforting treat that evokes memories of home-cooked meals and family gatherings.
Originating from British cuisine, the crumble gained popularity during World War II due to the scarcity of ingredients. Unlike pies, which require more butter, flour, and sugar, crumbles were an economical yet delicious alternative. Over the years, the crumble has evolved, with variations incorporating different fruits and spices. However, the combination of rhubarb and apple remains a classic, loved by many for its perfect blend of tart and sweet flavors.

- 1 cup rolled oats (not quick or steel-cut)
- 1 cup plain/all-purpose flour
- 3/4 cup (tightly packed) brown sugar

Step-by-Step Instructions for Perfect Rhubarb Apple Crumble
1. Preheat Your Oven
Begin by preheating your oven to 200°C/375°F (180°C fan). This ensures that your crumble will bake evenly, resulting in a golden, crispy topping and a perfectly cooked filling.
2. Prepare the Rhubarb Filling
In a large mixing bowl, combine the rhubarb pieces, apple cubes, white sugar, and orange zest. The combination of tart rhubarb and sweet apples is the key to a well-balanced filling. The orange zest, while optional, adds a subtle citrus note that enhances the flavors. Toss the ingredients well, ensuring that the fruit is evenly coated with sugar. Spread this mixture evenly in a 30 x 20cm (12 x 8″) baking dish.
3. Make the Crumble Topping
In a separate bowl, mix together the rolled oats, plain flour, brown sugar, baking powder, cinnamon powder, and a pinch of salt. These dry ingredients form the base of your crumble, with the oats providing a chewy texture and the cinnamon adding a warm, spicy note.
Next, pour in the melted unsalted butter. Using a wooden spoon, stir the mixture until the flour is fully incorporated. The goal is to achieve a sandy texture with small clumps. To do this, use a cutting motion or smear the mixture up the sides of the bowl. The butter binds the ingredients together, creating a crumbly, buttery topping that will crisp up beautifully in the oven.
4. Assemble the Crumble
With the filling spread evenly in the baking dish, it’s time to add the crumble topping. Grab handfuls of the topping mixture and squeeze to form lumps. Then, break these lumps into smaller clumps and scatter them over the filling. This method ensures that your crumble topping is uneven, which will result in a varied texture—some parts crunchy, others slightly chewy.
5. Bake to Perfection
Place the assembled crumble in the preheated oven and bake for 35 minutes, or until the rhubarb is tender and the crumble topping is golden brown. The aroma of baking rhubarb, apples, and cinnamon will fill your kitchen, a sign that your crumble is nearly ready. Once baked, remove the dish from the oven and let it rest for 5 minutes before serving. This brief resting period allows the filling to settle and the flavors to meld together.
6. Serve and Enjoy
Serve your Rhubarb Apple Crumble warm, straight from the oven. For a classic pairing, add a scoop of vanilla ice cream or a generous drizzle of pouring custard. The cold creaminess of the ice cream or the smooth warmth of the custard complements the tart, sweet filling and the crunchy, buttery topping, creating a dessert that is both comforting and indulgent.
Tips for the Best Rhubarb Apple Crumble
- Use fresh, in-season rhubarb and apples for the best flavor. If rhubarb is out of season, frozen rhubarb can be used, but be sure to thaw and drain it well to avoid excess moisture in your crumble.
- Experiment with different types of apples. While Granny Smith apples are preferred for their tartness, a mix of tart and sweet apples can add depth to the flavor.
- Add nuts or seeds to the crumble topping for an extra crunch. Chopped almonds, pecans, or sunflower seeds work particularly well.
- For a more intense flavor, try adding ground ginger or nutmeg to the crumble topping. These spices complement the rhubarb and apple beautifully.
- Make ahead: You can prepare the crumble in advance and store it in the fridge for up to 24 hours before baking. This makes it a convenient dessert option for dinner parties or gatherings.

Rhubarb Apple Crumble is a classic dessert that never fails to impress. The combination of tart rhubarb, sweet apples, and a crunchy, buttery topping is a match made in culinary heaven.
