this is a delightful recipe, that is so so soooooooooooo easy and very yummy. I found it in the 4 Ingredients 'red' cookbook.
1 x vanilla cake mix - the no name 70c ones
3/4 cup melted butter
400g tin pie apples (that is the original recipe - I use fresh apples, about 5 good sized granny smiths, peel, quarter and par cook in the m'wave for about 4 mins, then cut in half again)
200g Sour Cream
add melted butter to cake mix and combine to form a dough - press dough into a rectangular lined baking dish. Bake in a preheated 180 degree oven for 15 mins
combine sour cream & apple and pour over the base, top with cinnamon - as much or as little as you please.
return to the oven for a further 15 minutes.
cool in the fridge for a good couple of hours before removing from the dish and slicing - the longer it's in the fridge the better as it really needs to set.
I cut mine into squares for dessert or smaller rectangles for morning tea.
