Cut in the cold butter until a coarse crumb texture is achieved.
5 tbsp unsalted butter
Stir in granola and set aside.
1 cup granola
For the filling
Preheat oven to 375°F.
Wash, peel and slice apples about ¼ inch thick.
3 lb crisp baking apples (preferably a mixture such as Honeycrisp, Granny Smith, Pink Lady, or Braeburn)
In a large bowl combine apples, lemon zest, lemon juice, brown sugar, granulated sugar, cinnamon, and maple syrup. Stir to combine.
1 tsp lemon zest, 1 tbsp fresh lemon juice, 3 tbsp granulated sugar, 2 tbsp light brown sugar, ½ tsp ground cinnamon, 4 tbsp maple syrup
Melt butter in a 12-inch cast iron (or oven safe) skillet over medium-high heat.
4 tbsp unsalted butter
Once the butter is melted, add apple mixture. Cook until the apples become saucy, thickened and are beginning to soften, 8-10 minutes. Add the flour and stir to combine.
3 tbsp all-purpose flour
Add Calvados (or cider) and stir.
¼ cup Calvados (apple liqueur) or apple cider
Move skillet to preheated oven and bake until apples are softened and bubbling, 10-15 minutes.
Sprinkle prepared crisp topping evenly over the apples and return to oven until the crisp turns golden brown, approximately 4-6 minutes more.
