Best Apple Crisp Ever

Preheat your oven to 375°F (190°C).

Lightly grease a 9-inch square baking dish or a similar-sized pie dish.

In a large bowl, combine the sliced apples, granulated sugar, flour, cinnamon, nutmeg, and lemon juice. Toss gently to coat the apples evenly.

Transfer the apple mixture to the prepared baking dish.

Dot the top of the apple filling with the butter pieces.

In a separate large bowl, whisk together the flour, rolled oats, brown sugar, baking powder, and salt.

Add the cold butter pieces and use a pastry blender or your fingertips to cut the butter into the dry ingredients until the mixture resembles coarse crumbs. Don't overmix! You want to see small pieces of butter.

Stir in the chopped pecans or walnuts (if using).

Sprinkle the crisp topping evenly over the apple filling.

Bake in the preheated oven for 35-45 minutes, or until the topping is golden brown and the apple filling is bubbly. If the topping starts to brown too quickly, you can loosely tent the dish with aluminum foil during the last 10-15 minutes of baking.

Let the Apple Crisp cool for at least 15 minutes before serving. This allows the filling to thicken slightly.
