Apple filling

1. Preheat oven to 350°F and spray two ramekins (aff link) or mini round cocottes with nonstick spray (aff link). Set aside.
2. In a medium bowl, combine chopped apples and lemon juice and toss to coat. Add brown sugar, cornstarch, vanilla, cinnamon (and ginger, if including) and stir or toss to coat and combine.
3. Divide the apple filling evenly between the two prepare dishes, and set aside.

Crumb topping

1. In a medium bowl, combine flour, oats, brown sugar, cinnamon, salt, and nutmeg (if including) and whisk to combine.
2. Add cold, cubed butter and use a pastry cutter (aff link) or fork to combine. Once the mixture forms a large crumb that sticks together, spoon half the crumb mixture in an even layer on top of each dish of apple filling.
3. Bake for about 25 minutes, or until the topping is lightly golden brown and the apples are cooked through and soft. If desired, at the end you can set the oven to Broil to let it quickly brown the tops. Keep a close eye on it, as it will happen quickly!
4. Carefully remove from the oven, let cool slightly, then serve. Top with a scoop of vanilla ice cream, caramel sauce, or just serve as is – enjoy!
