Preparing Breakfast Apple Crumble is a simple and rewarding process. Follow these steps to create this delicious dish:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease an 8-inch square baking dish.
2. Prepare the Apples: Peel, core, and slice the apples. Place them in a large bowl.
3. Add Lemon Juice: Drizzle the lemon juice over the sliced apples and toss to coat. This prevents browning and adds flavor.
4. Mix with Sugar and Cinnamon: Add granulated sugar and ground cinnamon to the apples. Mix well until the apples are evenly coated.
5. Transfer to Baking Dish: Spread the apple mixture evenly in the prepared baking dish.
6. Prepare the Crumble Topping: In a separate bowl, combine rolled oats, all-purpose flour, brown sugar, and salt. Mix well.
7. Add Melted Butter: Pour the melted butter over the oat mixture and stir until everything is combined and crumbly.
8. Add Nuts: If using nuts, fold them into the crumble mixture for added texture and flavor.
9. Spread Topping: Evenly spread the crumble topping over the apples in the baking dish.
10. Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until the topping is golden brown and the apples are tender.
11. Cool Slightly: After removing from the oven, let the crumble cool for a few minutes before serving.
