Cinnamon and Brown Sugar Apple Crisp

1. Preheat your oven to 375 degrees. In a large bowl, toss the peeled and thinly-sliced Granny Smith and Fuji apples with the ground cinnamon.

2. Pour the apple mixture into a prepared 9-by-9-inch baking dish.

3. In a separate bowl, combine the unsalted butter, dark brown sugar, rolled oats and all-purpose flour. Use your fingers or a fork to mix everything together until it forms a crumbly topping.

4. Sprinkle this topping evenly over the apples in the baking dish.

5. Bake for 45 minutes, or until the topping is golden brown and the apple filling is bubbly. Let the crisp cool for a few minutes before serving with a scoop of vanilla ice cream.
