Apple Crisp

This recipe I learned from my momma. 

8 Crisp Apples (peeled, cored and thinly sliced)
¾ cup softened butter
1 ½ cup brown sugar
1 ½ cup quick cook oats
½ cup flour
2 tsp Cinnamon

Preheat oven to 350°.
Mix butter, sugar, oats , cinnamon and flour. Layer apples in a buttered dish and top with crumble.
Bake for 1 hr or until top is browned, bubbly and apples are tender.
