• Preheat your oven to 350℉.

Make the Filling

• Wash and cut the apples into thin slices. Peeling is optional, but recommended for a more consistent texture.
• In the bowl of apples, add lemon juice, granulated sugar, cinnamon, nutmeg, and vanilla. Mix around until the apples are fully and evenly coated.
• Pour the apple mixture into a pie dish or 8 inch baking pan. Set aside while you prepare the topping.

Make the Topping

• In one bowl, combine the flour, oats, brown sugar, and cinnamon. Stir to combine.
• Add the softened butter and finish mixing until evenly combined. It should be quite thick and able to be molded to the top of the apple dish.
• Pour the topping on the apples and spread to cover the top completely.
• Place in the oven and cook for 45-50 minutes. It will be done when the apples are bubbling and the topping is slightly browned.
• Scoop and serve by itself or with your favorite toppings!
