Peanut Butter Chocolate Protein Overnight Oats Recipe

My love for overnight oats knows no limit.

Add peanut butter (!!!) and chocolate (swoooooon) to the equation and you’ve got yourself a superstar breakfast.

Oh and did I mention there’s extra protein in them too?! *in Chandler’s voice* “could these BE any more perfect??”

If you’re asking yourself “okay wait, what are overnight oats?” I got you: overnight oats are uncooked rolled oats that soften overnight (or really, after a couple of hours) in the refrigerator with milk and other mix-ins. Once you have a basic recipe down, you can get experimental with your flavorings!

So here’s the basic recipe for overnight oats, then we can get to the chocolate peanutiness of it all. For any overnight oats recipe you’ll need at least:

  • old fashioned rolled oats. gluten free if they suite you
  • milk. I’m a plant milk kind of girl but you do you
  • nut butter or yogurt. this will (along with chia seeds) help to create a thick, creamier texture, but you can skip if allergies are a prob
  • chia seeds. might technically be optional but again, they make for a more pudding-like consistency
  • sweetener. use something pure if you can like honey or agave
  • flavoring. I use vanilla extract in my classic overnight oats recipe!

CAN YOU USE STEEL CUT OATS? I’ve gotten this question before on my Instagram page and the short answer is yes*. You can use steel cut oats but they will not soften anything like rolled oats will, regardless of their time in the fridge. So if that’s all you have that’s okay! Just know they’ll taste much chewier than rolled.

Okay, so now that we’ve got the basics of overnight oats down, let’s spice them up with the most classic of combos, peanut butter and chocolate. Literally and unarguably the PREMIER combination.

This recipe uses cacao powder (raw cacao beans milled into powder that retain more nutrients than cocoa powder), chocolate protein powder and unsweetened peanut butter to create our Reese’s style oats. These days you can find cacao powder in almost every grocery store, but note the spelling! Cocoa powder is heated when processed (dissolving many of the beans’ nutrients).

The best part about this recipe is that there is only ONE step! Mix everything together in something that can be covered (these glass jars are my favorite) and place into the refrigerator. In about 4 hours they’ll taste like heaven!

If you like overnight oats, you should also check out my Apple Cinnamon Overnight Oats or my Peanut Butter and Jelly Overnight Oats recipe as well. Peanut butter is (and always will be) a reoccurring ingredient in our household (God willing no one has any peanut allergies down the road!).
