This irresistible Plum Crumble is sweet, comforting, and wonderfully simple to make. It is made with juicy caramelized plums tucked beneath a crisp, golden, buttery crumble. Serve this easy fall dessert with custard or a scoop of cold vanilla ice cream.
Preheat oven to 190°C / 375°F / Gas 5. Lightly grease the oven dish and set aside.
Slice the plums into even wedges.
Add them to a baking dish, then add brown sugar, lemon juice, cinnamon, cornflour, and plain flour. Toss or mix until the plum slices are evenly coated.
Spread the plum slices in a single loose layer. This helps them soften evenly.
Combine flour, a little sugar, and a pinch of salt in a bowl or food processor. Add cold butter and rub it in with your fingertips until the mixture forms loose, sandy clumps. Or pulse in a food processor.
Assemble
Scatter the crumble over the plums without pressing it down. Leave gaps here and there so steam can escape and the topping can brown instead of steaming.
Bake for 35-45 minutes. Let the crumble sit for at least ten minutes before serving.
Serve this delicious plum crumble with ice cream or custard.

Notes
Plums: Do not precook the plums; cooking them beforehand makes them too soft once baked into the crumble.
Sugar: Plums are naturally sweet, so this plum crumble recipe doesn’t need much added sugar.
Add‑ins: Ginger powder, pumpkin spice, or a splash of rum or red wine can deepen the flavor of the filling.
Crumble: Scatter the topping loosely over the fruit rather than pressing it down; this keeps the crumble crisp instead of dense.
