Marshmallow Apple Crisp

8 large Granny Smith apples, cored and sliced

½ cup white sugar

2 ½ tablespoons all-purpose flour

1 teaspoon ground cinnamon

1 cup butter, melted

1 ½ teaspoons ground nutmeg

2 teaspoons ground cinnamon

1 cup firmly packed brown sugar

1 cup quick cooking oats

1 cup all-purpose flour

2 cups miniature marshmallows

Preheat oven to 375 degrees F (190 degrees C).

In a bowl, mix the apple slices, white sugar, 2 1/2 tablespoons of flour, and 1 teaspoon of cinnamon together until thoroughly combined; spread out into a 9x13-inch baking dish. In a separate large bowl, mix the melted butter with nutmeg and 2 teaspoons of cinnamon; stir in the brown sugar, oats, 1 cup of flour, and mini marshmallows until thoroughly combined. Spread the marshmallow topping evenly over the apples, and gently flatten the topping to a smooth layer.

Bake in the preheated oven until the apples are tender and the topping is golden brown, 30 to 35 minutes.
