Heat oven to 350. Spray the bottom of a 13 x 9 baking pan with cooking spray. In a large bowl cut butter into cookie mix using a fork or pastry blender. Stir in egg until mixture is crumbly. Reserve 1 1/2 cups of the cookie mixture. Press the remaining cookie mixture in the bottom of the pan. Now bake that for 15 mins. Sprinkle apple over the cookie mixture you just baked. Then mix caramel topping and flour together and drizzle over apples. Then sprinkle the reserve cookie mix over that and bake for 20 - 25 mins. Cool completely for about 2 hours.
