Baked Apple Crumble with Cinnamon Oat Topping

Preheat oven to 375°F (190°C).

Peel, core, and slice the apples into approximately 1/4-inch thick slices.

In a large bowl, combine the sliced apples, lemon juice, 1/4 cup brown sugar, 1 teaspoon cinnamon, and 1/2 cup flour (if using). Toss to coat.

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

In a separate bowl, combine the rolled oats, 1/2 cup flour, 1/2 cup brown sugar, 1/2 teaspoon cinnamon, and salt for the topping.

Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Sprinkle the oat crumble topping evenly over the apples.

Bake for 30-35 minutes, or until the topping is golden brown and the apples are tender. If the topping is browning too quickly, cover loosely with foil.

Let cool slightly before serving. Serve warm.
