Easy Homemade Apple Crisp

For the topping:
1/2 cup all-purpose flour
1 cup oats
½ cup brown sugar, packed
1 teaspoon cinnamon
Half to 3/4 stick cold butter, cut into pieces

For the filling:
6 cups chopped (1-inch pieces) tart apples like Granny Smith (about 6 medium apples)
2 tablespoons all-purpose flour
½ teaspoon cinnamon

Heat oven for 375 degrees F. Spray an 8-inch square (2 quart) baking dish with spray.

In a medium bowl, mix ¾ cup flour, the oats, brown sugar and cinnamon until blended. Cut in the cold butter with two butter knives or a pastry cutter until crumbly. Do not over mix. Set aside.

In a large bowl mix all the filling ingredients. Spread evenly in the baking dish. Sprinkle the oat topping evenly over it. Bake 30-35 minutes or until the topping is golden brown and juices are bubbling along the edges. Cool at least 20 minutes before serving.
