New overnight baked oatmeal recipe

I recently decided to look at some new recipes for baked oatmeal.  I wanted something soaked over night and not too sugary.  This is the recipe I decided to use from Stacy Makes Cents and it is delicious.  Since I have a family of 6, I double her recipe and as always, I do slightly change a few things, such as adding an acidic medium and a bit of whole grain flour to help break down the phytates in the oats and make the nutrients more digestible.  I also soak the dough in the oven with the light on to keep it warm instead of the fridge.

Ingredients:
4 cups rolled oats (old fashioned oats)
2 cups whole milk
Acidic medium to enhance digestion (I usually use apple cider vinegar)
1/2 cup whole grain flour
2/3 cups sweetener ( I use coconut sugar)
4 tablespoons melted coconut oil
4 eggs
3 teaspoons baking powder
1 teaspoon salt
2 teaspoons vanilla
1 teaspoon cinnamon
add-ins of choice: my girls usually prefer chocolate chips, raisins, craisins, etc.

1. In a mixing bowl, combine the oats, milk, acidic medium, and flour. Cover and stick in oven with light on overnight.
2. In the morning, add the remaining ingredients and mix well.
3. Pour into a greased 9x13 inch baking dish.
4. Bake at 350 degrees for 40 minutes.
