Preheat oven to 375°F
Grease a 1 1/2 quart square or round baking dish
6 apples peeled and sliced and place in baking dish.
1/3 cup butter
1 1/4 cups lightly packed brown sugar
Stir in until crumbly a mixture of:
2/3 cups Flour
1/4 teaspoon cinnamon
Sprinkle with crumbs over apples. Bake in preheated oven for 40 minutes or until apples are tender and topping is golden brown.
NOTE: I quite often double the topping and use a couple of extra apples.
