Yes, a crumble topping is so good! If you are making the caramel apple pie from scratch, you will only need two batches of the slab pie dough. Instead of topping the pie with crust, sprinkle the crumble topping over the top. This caramel apple slab pie will be the hit of the holidays, potluck, or party! There won’t be a slice left, so don’t forget to save a piece for you – Enjoy!
