Have you ever been annoyed when you get to the bottom of the peanut butter jar and there's quite a bit of peanut butter left, but it's a pain in the butt to scrape it out? Then you end up just throwing the jar away because it's too much of a hassle to get those last little bits out.

Well, that's how I feel about almost empty jars of peanut butter.  They're annoying.

The thing is, I really really dislike wasting food.  Waste not, want not is my philosophy, so I trudge through scraping them out to save a few pennies.

Until now.  I will never scrape a peanut butter jar again.

All of that peanut butter in the bottom of the jar can just stay put from now on.  And not only is it going to be used, but I'm also going to use the jar itself as a serving bowl.  This is genius, guys.  Bear with me here.

All you have to do is add some oats, some almond milk, (in this case chocolate almond milk; you're welcome), and half of a nice ripe banana, and stir it all up real good right in the jar.  Then you put the lid back on and put it in the fridge until morning.  How easy was that?!

No more jar scraping.  The oats will soak up all of the yummy milk mixture overnight and in the morning breakfast is already made!  So darn easy.  In the morning you just give it a little stir and you're good to go.  I like to eat my overnight oats cold, but a quick zap in the microwave will take the chill off for those of you who prefer a hot breakfast.  Either way, you're set in the morning with a healthy breakfast to get you going.  Lord knows, the last thing I want to think about when I wake up is eating breakfast, if I'm going to be honest.

Breakfast is important, though, so I'm taking the overnight oats idea and running with it.  This recipe is easy for me, the kids like it, and I don't have to scrape the peanut butter jar.  Happiness any way you look at it!  The next time you're coming close to your peanut butter jar being empty, give this recipe a shot!  Peanut butter, chocolate, and banana oatmeal is just a night in the fridge away!

  1. Didnt have a banana so i used an apple. Also used skim milk with a little bit of chocolate syrup. We shall see tomorrow how it is!

  3. That looks like a 340-gram jar. The almost-empty jar sitting in the fridge for the past few days awaiting the oats is 794 grams. Is it logical to adjust the proportions accordingly? E.g., a full cup of oats, a whole banana, etc? Might throw in a few grapes as well

    1. My jar was 425 grams. If you adjust the amount of ingredients it will work, but you may end up with a less peanut butter taste if there's not too much peanut butter left in your jar.
