1-First, preheat your oven to 180°C (350°F) and get your apples ready. Peel and cut 2 pounds of Granny Smith apples into 1/2-inch cubes for a juicy base. This step takes about 15 minutes total, setting the stage for the rest.

2-Next, toss the apple cubes in a bowl with 1 tablespoon flour, 1/2 cup white sugar, and 1/2 teaspoon ground cinnamon. Add 2 tablespoons of lemon juice to mix well, which helps enhance the flavor and keep everything fresh. This combination creates a filling that’s just right.

3-Spread the apple mixture evenly in a 1.5-quart baking dish. For the topping, combine 1 cup rolled oats, 1 cup flour, 1 cup brown sugar, 1/2 teaspoon baking powder, 1 teaspoon cinnamon powder, 1/2 cup melted unsalted butter, and a pinch of salt until clumps form. The total time for prep is around 15 minutes, leading to 40 minutes of baking for a grand total of 55 minutes.

4-Evenly sprinkle the topping over the apples, then bake for 30 to 40 minutes until it’s golden brown. Let it stand for 10 minutes before serving, perhaps with vanilla ice cream. This approach works well for busy schedules, as you can prepare up to the topping step ahead and bake later.
