Preheat oven to 350 degrees.

In a 9X13 baking dish, spread the 6 cups of raw oats out evenly. If you are going to be adding fruit to the bake, add them now and mix into the oats.

Mix the eggs and milk together in a separate bowl, then pour mixture over the top of the oats.

Allow oat mixture to sit for 5 minutes as the oats start to absorb the liquid.

Bake for 20-25 minutes, or until the liquid has been totally absorbed.

Take the oatmeal bake out of the oven, then immediately take a knife and run it along the edges. Because there is no oil or grease, it will be easier for the oats to stick to the dish. However, if you run a spatula or knife allow the edges while it's hot, then they won't stick.

Now, allow the bake to cool for 10 minutes, then serve. If you are not eating right away, cut into pieces and store in a container in the fridge. The bake will last 4-5 days in the fridge.
