Preheat your oven and lightly grease a baking dish with vegan butter or cooking spray. If you’re making this recipe in a larger baking dish, just make sure the apples fill it about ¾ of the way, then make some extra topping.
In a large bowl, combine the chopped apples with flour, sugar, melted butter, cinnamon, and vanilla extract. Toss everything well until the apples are evenly coated with the mixture, then transfer it to the prepared baking dish.
In another bowl, whisk together the flour, rolled oats, sugar, spices, and salt. Add the vegan butter and work it into the dry ingredients using your fingers or a pastry blender until the mixture resembles coarse crumbs. Make sure the butter is worked in thoroughly so each bite is consistently delicious. Evenly sprinkle the oat and flour mixture over the apples in the baking dish.
Place the dish in the preheated oven and bake it until the top turns golden brown and the apple filling is bubbly and tender when tested with a fork. Remove the apple crisp from the oven and allow it to cool for a few minutes before digging in. Happy eating!
