Combine all ingredients in a crock pot and cook on low 6-8 hours. Alternately, for a late breakfast, combine all ingredients, refrigerate overnight, and cook on high for ~3 hours.
Notes
If your crock pot tends to run hot, you plan to cook oats closer to 8 hours, and/or you prefer a thinner consistency, add up to 1 cup water to the recipe or thin it out as needed prior to serving. Crock pots with timers are also wonderful so you don't have to worry about getting up for breakfast!
