Step by Step Method

Step 1

Grease or butter an 8 x 8 inch baking dish.

Step 2

Next, mix together the butter (or the coconut oil), egg (or flaxmeal and water), milk, maple syrup, vanilla, cinnamon, baking powder, and salt in a large bowl.

Step 3

Stir in the oats (and anything else you would like to add in).

Step 4

Pour it all into the 8 x 8 baking dish and cover with plastic wrap. Place in the refrigerator for at least 8 hours.

Step 5

Heat the oven to 350 degrees Fahrenheit. Take the plastic off the baking dish. Stir the contents one more time.

Step 6

Bake the dish uncovered for 45 minutes, or until the center is just set and the oatmeal is puffed. If you want any nuts on top, you can sprinkle them on during the last 5 minutes of cook time.

Step 7

Refrigerate for up to 4 days. Servings can be reheated with a little milk added if necessary.

Loved this! It came out so good, but wished I had paid closer attention to the time in the oven (was in a meeting). I did add extra cinnamon because I love cinnamon and love the ease of prepping it the night before. I will make it like this a lot this winter! Thanks so much, WAIGEN, for sharing! Made it for Only The Lonely.
