Mix the dry ingredients of old fashioned oatmeal, sugar, All Spice, baking powder, and salt in a large mixing bowl. In separate mixing bowl mix the wet ingredients of vanilla, diced apples, Raisins, eggs, melted butter and milk. Once both bowls are completely mixed combined the bowls and mix together.

Fill four 9x13 baking pans with the Apple Harvest Baked Oatmeal Mixture.

Bake all four 9x13 baking pans of baked oatmeal at 350 for 30 minutes. Once baked and then cooled you can cut the baked oatmeal and freeze as individual servings to heat up on a later day. Or you can freeze the entire 9x13 pans (wrapping in foil and plastic wrap) to reheat on another busy morning. The single portions are quick to heat up in the microwave.

To reheat a defrosted 9x13 pan just remove the foil and plastic wrap, and place it bake in the oven at 350 for up to an additional 30 minutes.
