To be honest, we’d liken this “cake” to an amped-up mega-delicious apple crisp. The base is made with baking apples, cinnamon, and a squeeze of lemon juice for balance, just like pie filling. In the spirit of dump cakes, the fruit mixture is covered with a crispy topping that you quickly dump together (we added some rolled oats for texture, plus cinnamon and ginger for oomph). For a finishing touch that plays up the dessert’s similarity to apple crisp, we decided to top it off with an extra layer of streusel. And not just any streusel: big, buttery, crunchy crumbs.
