Preheat oven to 375. Spray a 9x9 casserole dish with cooking spray (I used coconut oil). Add all filling ingredients to a large bowl and mix well. Set aside while you make the topping. Add all topping ingredients to a food processor and pulse a few times until it resembles granola. Add filling to the casserole dish and spread the topping overtop evenly.
Bake for 35-40 minutes until cooked through and browned on top. Serve topped with dairy free ice cream or whipped cream! Enjoy!
