Apple cake with crumble topping

Method

1. Preheat oven to 180/160/ Grease and line a 9“ cake tin
2. Put all the ingredients, except the apple into a mixer and beat for about 3 mins.
3. Whilst the cake batter is mixing, peel and grate the apples.
4. Put half the mixture into the tin, cover with the grated apple and top with the remaining cake batter. Sprinkle over the crumble topping and bake for 1 hour. Check with a skewer to see if it is cooked in the middle, it may take longer depending on your oven. If the cake is still wet, keep testing after 10 min intervals until cooked through. If the crumble topping begins to brown, cover with tin foil.
5. Remove from the oven and allow to cool slightly. Dust with icing sugar and serve with some clotted cream.
