For the best flavor, use a mix of sweet and tart apples, such as Granny Smith and Honeycrisp. Ensure that the oat mixture is well pressed into the baking dish to form a sturdy crust. If you prefer a richer flavor, you can add a handful of nuts, like walnuts or pecans, to the oat mixture. Adjust the sweetness of the apple filling to your taste by altering the amount of granulated sugar.
