Toffee apple pan crumble

Method

1. Heat the oven to 190°C/170°C fan/ gas 5. To make the topping, rub together the flour and 150g butter in a large bowl until it resembles breadcrumbs. Stir in the brown sugar and hazelnuts, then set aside.
2. In the frying pan, melt the 80g butter and granulated sugar with the split vanilla pod or paste, shaking the pan to swirl the mixture together as a caramel. Try not to fiddle with it too much. Cook for 2-3 minutes, then add the apples and coat in the caramel. Cook for 8-10 minutes more until the apple turns golden.
3. Sprinkle the crumble topping over the apples, then transfer the pan to the oven and bake for 25 minutes. Serve with cream or ice cream.
