What Makes This Plum Crumble So Special

• Plums: Fresh, ripe plums bring natural sweetness and a touch of tartness. You can use either red plums or purple Zwetschgen (a type of European prune plum). Red plums tend to be juicier and slightly sweeter, while Zwetschgen are firmer, more tart, and hold their shape better when baked. Both work beautifully, so choose based on your preference!
• Hazelnuts: Roasting and peeling the hazelnuts gives the crumble a deeper, richer flavour and a delightful crunch.
• Cold butter: Essential for a crisp crumble topping. Make sure it’s cold to get that perfectly crumbly texture.
• Flour & Sugar: Simple pantry staples that hold the topping together and add just the right amount of sweetness.
• Cinnamon: A pinch of ground cinnamon adds warmth and a little spice to balance the plums.

Easy Plum Crumble: Step-by-Step Instructions

1. Prepare the hazelnuts: Roast the hazelnuts until the skins crack, then rub them in a kitchen towel to peel. Coarsely chop the hazelnuts for the crumble topping.
2. Make the filling: Toss sliced plums with a little flour and cinnamon, then spread them in a baking dish.
3. Assemble & bake: Combine flour, sugar, and cold butter to make the crumble, stir in the hazelnuts, and sprinkle the mixture over the plums. Bake until the topping is golden brown and the filling is bubbling.

Ingredients

For the filling:

• 15 ripe plums, sliced (about 1.1 kg)
• 1 tablespoon flour
• 1/4 teaspoon ground cinnamon

For the hazelnut crumble:

• 100 g whole hazelnuts
• 100 g flour
• 50 g mascavado brown sugar
• 115 g cold unsalted butter, cubed
• Pinch of salt

Method

1. Roast and Peel the Hazelnuts: Preheat your oven to 350°F (180°C). Spread the hazelnuts on a baking sheet in a single layer and roast for 8-10 minutes, or until their skins crack. Remove from the oven and wrap the warm hazelnuts in a clean kitchen towel. Rub them together inside the towel to remove most of the skins (it's fine if some bits remain). Coarsely chop the peeled hazelnuts and set aside.

2. Prepare the Filling: In a large bowl, toss the sliced plums with the flour and cinnamon until evenly coated. Transfer the mixture to a 20 x 20 cm baking dish, spreading it out evenly.

3. Make the Hazelnut Crumble: In a medium bowl, mix together the flour, sugar, and a pinch of salt. Add the cold, cubed butter and use your fingers to rub it into the dry ingredients until it forms a coarse, crumbly texture. Stir in the chopped hazelnuts.

4. Assemble and Bake: Evenly sprinkle the crumble mixture over the plums in the baking dish. Bake for 35-40 minutes, or until the topping is golden brown and the plum filling is bubbling. Allow the crumble to cool slightly before serving.

5. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy!

Notes

Food processor method to make crumble topping: For an even quicker method, you can make the crumble topping in a food processor. Simply place the flour, sugar, and salt in the food processor. Add the cold, cubed butter and pulse until the mixture resembles coarse crumbs. Once it’s ready, transfer the crumble to a bowl and stir in the chopped roasted hazelnuts. This method ensures a perfect crumbly texture with minimal effort!
