What Are Overnight Oats?

Overnight oats is a simple make-ahead breakfast recipe that is made by soaking oats in milk overnight (or at least for 4 hours). Unlike traditional oatmeal, overnight oats are typically eaten cold.

Are Overnight Oats Healthy?

Yes, overnight oats are a pretty healthy breakfast meal prep option. Oatmeal is a great breakfast choice to fill you up and avoid pre-lunch hunger pangs. This peanut butter overnight oats recipe uses whole fiber-rich oatmeal, natural sweeteners, protein-packed peanut butter, and some antioxidants from dark chocolate!

People generally think of oatmeal as a healthy food option, and this Cleveland Clinic article backs that thought up! Did you know that eating a daily bowl of oatmeal can help to reduce BMI, lower cholesterol, and even improve blood sugar control? WOW!

I mean, do you need any more reasons to try out this delicious peanut butter cup overnight oats recipe??

How Do You Eat Peanut Butter Cup Overnight Oats?

It’s kinda like eating creme brulee– or a magnum crack shell ice cream (my hubby’s favorite!). After the peanut butter overnight oats have to be set (about 4 hours) you’ll want to hit your chocolate shell with the back of your spoon to break up the chocolate before eating this delicious overnight oats cup!

What Containers Should I Use For Overnight Oats?

I will often use my favorite glass meal prep containers for my overnight oats–especially if I am making a big batch for later. But sometimes, if I am planning on eating my overnight oats sooner, I will use our clear plastic drinking cups and cover the oatmeal with plastic wrap. I am a big fan of using what you have on hand.

Peanut Butter Cup Overnight Oats Ingredients You’ll Need

Gather the ingredients below to make the BEST overnight oats you have ever had! Check out the ingredients below for tips and substitutions.

  • Peanut Butter
    • Use crunchy peanut butter for added texture or creamy for the traditional peanut butter cup texture. Not a peanut butter fan? You can also substitute your favorite nut or seed butter.
  • Oats
    • Rolled oats or old-fashioned oats are the best to use in overnight oats– just make sure to let the oats soak up the liquid for at least 4 hours in the refrigerator for the best texture.
  • Dark Chocolate
    • You can use milk or dark chocolate, we like dark chocolate at our house–and its full of antioxidants!
  • Olive Oil
    • Add a TINY amount of olive oil (or coconut oil) to the chocolate to make it more spreadable and to make it easier to “crack” the top of.
  • Flaky Salt
    • Flaky salt is the BEST ingredient of all time! Add it to anything–and it will elevate it! We add a sprinkle on top of the chocolate layer because YUM!
  • Honey
    • Honey is the BEST sweetener hands down in this recipe. Not only is it a natural sweetener, but peanut butter and honey are a match made in heaven. You can also use pure maple syrup or agave nectar.
  • Almond Milk
    • You can use any milk that you like in your overnight oats. I like to use unsweetened almond milk or soy milk in mine.

Can I Make Overnight Oats with Water?

Technically, yes, but I wouldn’t recommend it. Overnight oats are best with a creamy base. Water will work, but I would only use water in hot oatmeal.

What Should I Serve with Chocolate Peanut Butter Cup Overnight Oats?
