Mason jars seem to be all the rage these days, don’t they? From holiday décor to pendant lights, jars seem to be everywhere. Once used mainly for canning, you can make pretty much any kind of recipe in a mason jar these days. Here I’ve created two different breakfast-in-a-jar options, one hot, one cold. The cold breakfast jar is great for putting together the night before and using as a grab-n-go breakfast in the morning. It’s perfect for anyone who tends to rush out the door without breakfast.
