I made this in a 9 inch cake pan the first time, and had to pack the crust in a little more then I liked. In a larger pan it's perfect.
8 apples - I used Cortland for it's mild flavor, but would use something firmer next time. If your apples are huge use your judgement on how many to use.
2 tsp cinnamon
1 tsp nutmeg
1 tsp allspice
Peel and slice apples, and toss with spices to fully coat. Spread evenly into a 9x12 pan.
1 cup Wheat Flour
1 cup Oatmeal - quick oats
3/4 cup Brown Sugar
1 stick + 5 tbsp unsalted butter
Blend on pulse in a food processor until combined and in large crumbs. Top apples with oatmeal mixture and lightly drizzle with real maple syrup. Bake in 350 degree oven for 30-45 minutes until crispy.
