Overnight oats are one of my go-to breakfasts because they taste great and can be made it a variety of flavors. They do take a little bit of prep time, but this is done the day before you intend to eat them. That makes them a filling, grab-and-go meal and I love knowing exactly what ingredients are in the jar. Check out this recipe for a peanut butter banana version of overnight oats.

Overnight Oats for a Quick, Make-Ahead Breakfast

I have to admit: I used to hate overnight oats. I liked the taste and I enjoyed the texture of oatmeal. However I could not get used to the COLD temperature. Overnight oats are prepped the night before you want to eat them and sit in a jar or container in the refrigerator. Thus, the next morning they are nice and chilly.

Well, two things have happened since: some mornings I actually enjoy the cold oats (especially on a hot summer morning). And guess what else? You can totally warm up overnight oats with a quick spin in the microwave! I was a couple dozen jars into my oats adventuring before it dawned on me to heat them up! LOL Anyway, problem solved.

This version combines peanut butter and bananas in a tasty flavor combination. It is also a great way to use up the inevitable overripe banana (or three) that shows up on your kitchen counter!

You can experiment with this basic recipe and try other flavor combinations. I also love using PB2 peanut butter powder (regular or also the version with cocoa!) sometimes, instead of peanut butter.
