Preheat the oven to 180oC. Scatter oats on a baking tray and toast in the oven for 3-4 minutes until they start to release a nutty aroma. Set to one side.
Put the plums in the pan with the water and sugar and place over a low heat, stirring until the sugar dissolves. Add the wine and spices and bring to the boil. Poach until the plums are just beginning to soften. Add the blackberries and cook for a further 2-3 minutes.
Put all the crumble ingredients into a large mixing bowl and combine lightly with your fingertips. Stir through with a fork so that it doesn't clump together.
Ladle the fruit and juices into a baking dish and cover evenly with the crumble mixture. Bake for 20-30 mins until the topping is golden and crunchy.
Serve warm with cream or custard.
