The topping was Crumble up a wheat breakfast biscuit mix it with a little light brown sugar and sprinkle onto the base of the cake tin.
Place the cake tin in the oven for 10 minutes.
|the topping, bit crispy but nice|
I think mine could have done with a minute less, it was a wee bit brown.
Once I had caramelised the mixture I topped it with a layer of a bog standard cake mix but using diabetic friendly sugar substitute, I then added a layer of peeled and cooked apple slices and uncooked blackberries and topped with another layer of sponge mix. Then put it back into the oven until cooked.
