This dessert was delicious!! It was easy to make and went together quickly. The tartness of the Granny Smith apples was complemented by the rich, sweetness of the topping. My family really enjoyed this and ate it up! The only thing that I did differently was to use old-fashioned oats because that is what I had on hand. Next time, I think I would leave out the salt in the topping. Between the butter and the salt, it was just a tad too salty for our tastes. Thank you for sharing this fantastic recipe...it is definitely a keeper!!
