Easy Apple Crisp

I've made this one a few times. I got the recipe originally from HERE and it is absolutely delicious. I make it with less brown sugar than stated, and it's still great. And as the recipe states, it is super easy. Serve with vanilla ice cream for a heavenly dessert!

6-7 apples - peeled, cored and sliced (i used 3 granny smith and 4 golden delicious)
1 cup water
1 (18.25 ounce) package white cake mix
3/4 cup packed brown sugar
1 teaspoon ground cinnamon
1/2 cup butter, melted


Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
Arrange apples in an even layer in bottom of baking dish. Pour water over apples.
In a medium bowl mix together cake mix, brown sugar, and cinnamon. Stir in melted butter or margarine until ingredients are thoroughly blended; mixture will be crumbly. Sprinkle mixture over apples.
Bake in preheated oven for 50 to 55 minutes
