In a large mixing bowl combine all of the ingredients. Mix thoroughly.
Spray 3.5 quart casserole crock pot (or a 4 quart oval crock pot) with nonstick cooking spray. Pour batter into the prepared slow cooker.
Cover and cook on low for 4-6 hours. (Note: you can cook on high for 2-3 hours but be careful and keep an eye so that it doesn't burn - some slow cookers run VERY hot when on high - especially newer ones)
Then serve!
Notes
PLEASE NOTE: If you have a slow cooker with a metal insert, please pay attention to your cooking times. The problem with slow cooking with metal inserts is they tend to burn foods like this (casseroles, etc.) because the metal gets very hot, very quickly so it burns the outer edges before the middle can get done. As opposed to traditional ceramic inserts that heat evenly and a little slower. If using metal, I suggest cooking on low and keeping an eye on it throughout the process. Please use your own knowledge of your slow cooker to adjust cooking times. There are so many different, types, shapes, sizes of slow cookers these days. Some older ones warm up super slowly and new ones can get burning hot very quickly so that is why there is a wide range of cooking times. I do not recommend using a round slow cooker for this recipe. It should be a casserole or oval slow cooker.
To make in the oven: Preheat to 375f degrees. Spray a 9x13 baking dish with nonstick cooking spray. Bake for about 35-45 minutes (until the center is set and not jiggly.)
