Notes
If you need the apple pie oatmeal to be nut free, use homemade hemp milk or oat milk in place of almond and substitute pumpkin or sesame seeds for the walnuts.Adjust the cooking time based on personal texture preference. The longer you bake it, the chewier it will be.Store leftovers in the fridge once cooled for 3-4 days. Reheat in the oven at 250F and add a splash of milk to the dish first.See the blog post for instructions on making it in advance.
