We LOVE baked oatmeal at our house, so I am linking to my favorite recipe at Kristie's request.
Urban Homemaker has the recipe that we use:
Hot Whole Grain Cereals for Breakfast
She uses the two-stage method, so you soak the oats overnight in buttermilk, kefir, or yogurt (I use buttermilk). You can use sugar instead of Sucanat if that's what you have available - I only use 1/2 cup of either. I only use one egg. Yummy! It's sooo good!
Here's another one to try that uses precooked oatmeal if you have leftovers. It's from Large Family Logistics, so it's a big recipe:
Here's another one with "normal" ingredients:
Amish Baked Oatmeal
I wonder how this would work in a crockpot. Has anyone tried it?
