Ingredients

Apple Filling

  • 4 granny smith apples
  • cup granulated sugar
  • ¼ cup brown sugar
  • 1 teaspoon cinnamon
  • 4 tablespoons salted butter chopped small

Oatmeal Cookie Crumble

  • 1 pouch (17.5 oz) oatmeal cookie mix
  • 1/2 cup (1 stick) salted butter melted
  • ½ cup chopped pecans
  • vanilla ice cream, caramel syrup, chopped pecans optional for serving

Instructions

  • Heat oven to 325°. Prepare a 9x9 baking dish by spraying with cooking spray. Set aside.
  • Peel each apple and thinly slice OR chop into small chunks. Place apples into a mixing bowl.
  • Add the brown sugar, granulated sugar, cinnamon, and chopped butter into the apples and stir until all the apples are coated in the cinnamon & sugar mixture. Dump the apples into the prepared pan and spread out evenly.
  • In the same bowl combine the oatmeal cookie mix, melted butter, and chopped pecans. Stir together until thick crumbles form. Sprinkle it over the apples in the baking dish.
    * DO NOT prepare the cookie mix according to package directions before adding it into the bowl. Just dump the dry contents from the pouch.
  • Bake for 40-50 minutes or until apples are at desired cook, the topping is a light golden brown, and the edges are bubbly.
  • Let the apple crumble sit and rest for 10-15 minutes before serving with vanilla ice cream, caramel syrup, and additional chopped pecans (if desired).

Notes

Baking Dish : I love this recipe using the 9x9-inch baking dish. It produces a thick apple layer and a thick crumble topping. If wanted, use a 9x13-inch baking dish instead. Check the cook time because it won't need as long to cook. Like maybe 30 minutes or so. 
Apples : I use Granny smith apples because I love the tartness of them paired with the sweet crumble. If you use another apple make sure it's not a super sweet one (like red delicious) maybe try Gala, Fuji, or Honeycrisp.
