I know I left you hanging on Friday by saying I specifically whipped up homemade eggnog to use in a recipe, so today I am telling you why I went through all that trouble. I used it in slow cook oatmeal! Why? Because there’s nothing better than breakfast ready and waiting for you in the morning. And when you live by yourself that notion is pretty much impossible (without a slow cooker).

The eggnog added the perfect amount of sweetness to the oatmeal, which is why you don’t see any sugar in the ingredient list. So yes, homemade eggnog was worth the extra time in order to make this oatmeal. Eggnog may actually become a year round thing so I can continue to have a supply of this oatmeal. All to myself.

Also, I would like to point out that you can cook this oatmeal two different ways in your slow cooker. The first method cooks on low continuously, and leaves you with crispy edges along the walls of the slow cooker. If you would prefer not to have those edges, cook it on high for a short time and then it stays in the slow cooker while it cools overnight.

It’s as if you blast it with heat and then let it gradually go down to low and then off, which means you will have to heat up the finished oatmeal in the morning. The latter method is the one I used. As you can see in my old picture below, I still had a little bit of the crispy edge phenomenon when I made this recipe in the past using a 6 quart slow cooker (because it’s all I had at the time) but I thought it added great texture.
