Put the cream, butter and sugar in a non-stick pan over a medium heat
Stir until the butter has melted, then continue to heat until you have a thickness resembling thick gravy. It might take up to 10 minutes. Pour into a bowl to cool.
Place the apples in the pan you were using for the sauce and stir in a couple of tablespoons of the toffee sauce.
Cook the apples over a medium heat for about 5 minutes, stirring regularly until just soft, then tip into a greased oven dish.
Pour in the toffee sauce.
Add the dates.
Make the topping
Preheat the oven to 200C (180C fan, 400F).
Rub the flour and butter together.
Stir in the sugar and cinnamon then sprinkle on top of the apples - don't press down.
Bake!
Put the whole crumble in the oven for 20 minutes until lightly browned and bubbling.
