Peel, core, and chop apples into ½ to 1” chunks. Spray a 2 quart baking dish with non-stick cooking spray, set aside. Preheat oven to 375℉ with rack positioned in the center of the oven.
Place all filling ingredients in a large mixing bowl and gently toss to combine. Pour into a prepared baking dish.
Place the softened butter and brown sugar in a medium mixing bowl. Mix with a hand mixer on medium speed until light and fluffy.
Add in the flour and cinnamon and beat on medium low speed until combined. You should be able to squeeze the dough together into a ball without it crumbling apart. If it won’t hold together when squeezed, add 1 tablespoon cold water.
Grab handfuls of the dough, squeeze it tightly, then crumble over the fruit.
Bake in the preheated oven for 45 minutes to 1 hour, or until the center is bubbly, and the apples are crisp tender. Cool for 15-25 minutes before serving, this will allow the fruit mixture to continue to thicken.
Notes
If your crumble topping browns too quickly, tent loosely with foil for the last 20 minutes of cooking.
Place a baking sheet underneath the dish to catch any potential drips during baking.
