Little Fruit Crumbles

100g blueberries
100g blackberries
200g raspberries
100g demerara sugar, plus a little extra to flour
75g unsalted butter, slightly softened
50g porridge oats

Serves 4

Preparation time: 15 minutes
Cooking time: 30 minutes

Preheat the oven to 200°C, gas mark 6. Lightly grease the sides of 4 x 225ml ovenproof ramekins and place on a baking sheet. In a bowl, mix all the berries together with 50g of the sugar and divide between the dishes, pressing them down gently.
Put the flour in a bowl and add the butter, cut into pieces. Rub in with your fingertips until the mixture just starts to bind together. Stir in the remaining sugar and the oats to make a coarse crumble. Scatter the mixture over the fruits, piling it up in the centre as it will sink after baking. Sprinkle with a little extra sugar. Bake for about 30 minutes until the crumble is golden and the fruits have started to bubble up.
