Preheat oven to 350F.
Using a fork, smash together all the topping ingredients until well combined and crumbly.
Wash, peel and chop apples into thin slices.
In a pie pan, mix the chopped apples with the remaining filling ingredients until evenly distributed.
Sprinkle the topping evenly over the apple mixture.
Bake at 350F for 30 minutes or until bubbly and apples are tender when pierced with a fork.
Serve warm with vanilla ice cream and a sprinkling of cinnamon.
This is a family recipe from Bethany's mom Marie.
