Slice the unpeeled honey crisp apples and place the slices in the cast iron skillet.
Sprinkle cinnamon, brown sugar and vanilla onto the apple slices and mix them together.
Add 6 pats (small slices) of butter and fry the apples over medium heat for 15 minutes or until the contents become soft. Make sure to stir the apples while frying.
Once done frying, pour the cup of water into the skillet and mix it with the apple slices.
Let the apples simmer while you make the crisp topping. Make sure to keep tabs on your skillet to avoid burning the apple slices.
Preheat the oven to 350° Fahrenheit.
Get a large mixing bowl and pour in granola, chopped pecans, cinnamon, brown sugar and flour.
Add the softened butter and mix the contents together until its texture becomes 'crumbly.'
Sprinkle the crisp topping over the apple slices while it’s still in the skillet.
Bake the dish for 15 minutes or until it becomes golden brown.
Serve with ice cream if desired.
