Ok. I’m not sure when I’m going to make an attempt, but I will send the recipe to you. Actually, I’ll go ahead and give you the link. I would only be using the crust. I’d layer the apples, then pour the topping as I recall it -— 2 cups sour cream, 2 cups powdered sugar, 1 beaten egg, 1/2 tsp cinnamon, and zest of 1 lemon. Pour over and bake. I’m guessing 325°F. Check after 30 minutes, to see if knife comes out clean.
Here’s the link for the cake -—

Thanks. I’ve put it on my desktop with your instructions for the topping.
