Chocolate Peanut Butter Overnight Oats are a rich, creamy spin on the classic—easy to prep and full of chocolatey, nutty flavor.

Peanut butter overnight oats, ready to be enjoyed on the go, with a peanut butter swirl mixed in and topped with chocolate chips.

Peanut Butter Overnight Oats

I love breakfasts that taste like dessert, so I turned one of my favorite treats—Reese’s cups—into these chocolate peanut butter overnight oats.

They don’t have actual candy in them, but the mix of chocolate and peanut butter gives serious Reese’s vibes.

I can’t decide if I love these or the brownie batter oats more, but overnight oats in general are a win—quick, easy, and fun to change up (especially when they taste like a treat!).

A container of special dark cocoa powder, the key ingredient used in this breakfast recipe.

Ingredient In Peanut Butter Overnight Oats

  • Peanut Butter: Use creamy, not chunky, so it stirs in easily.
  • Vanilla Extract & Salt: Boosts flavor and balances the sweetness.
  • Greek Yogurt: Choose a sweet, mild yogurt—honey vanilla works best.
  • Milk: Use your favorite milk, but unsweetened almond milk is my fave.
  • Old-Fashioned Oats: Stick with old-fashioned oats; quick oats get too mushy.
  • Cocoa Powder: Dutch cocoa is smoother and less bitter than regular cocoa powder.
  • Maple Syrup: Start with less and add more later if needed.
  • Optional Dark Chocolate Chips: Add them right before eating so they stay firm.
Mixing all the ingredients for chocolate peanut butter overnight oats in a bowl, followed by transferring the mixture to a jar for chilling.

How To Make Peanut Butter Overnight Oat

  1. Combine creamy peanut butter, vanilla extract, a pinch of salt, honey vanilla Greek yogurt, unsweetened almond milk, old-fashioned oats, Dutch-process cocoa powder, and maple syrup in a bowl or jar.
  2. Mix everything well until the peanut butter is fully blended.
  3. Cover and refrigerate overnight or for a minimum of 30 minutes to allow the oats to thicken.
  4. Optionally, top with dark chocolate chips before serving. Enjoy within three days.

Quick Tip

Because it’s thick and sticky, make sure to really stir in the peanut butter. These oats won’t taste as good if the peanut butter isn’t thoroughly mixed in. I like to use the back of my spoon to mash it throughly into the other ingredients.

A cup filled with the delicious and sweet breakfast, ready to be enjoyed.

Ingredients

Instructions 

  • In a small bowl, jar, or plastic container, stir together the peanut butter, vanilla extract, pinch of salt, yogurt, almond milk, old-fashioned oats, cocoa powder, and maple syrup.
  • Stir well and make sure the peanut butter is mashed in thoroughly.
  • Cover the container and refrigerate overnight or until sufficiently cooled and thickened. (Sometimes I’ll even make them in the morning, get ready, and then eat them—they are great even after 30 minutes in the fridge.)
  • When ready to eat, if desired, top with dark chocolate chips. Store overnight oats in the fridge for up to 3 days.

Recipe Notes

Note 1: The yogurt can totally overpower these oats, so get a mild tasting, sweet yogurt. My favorite is honey vanilla Greek yogurt (from Greek Gods®). Whatever yogurt you choose to use, make sure you like it plain or you likely won’t love it in these oats.
Note 2: I recommend a Dutch-process cocoa powder as opposed to a plain (natural) cocoa powder. Any Dutch-process cocoa powder will work, but Hershey’s® sells a Special Dark cocoa powder that is readily available at most grocery stores.
Note 3: I like 1 tablespoon pure maple syrup best, but sweeten to personal preference (1/2 tablespoon up to 2 tablespoons maple syrup or 1/4 teaspoon liquid stevia).
Storage: You can keep Overnight Oats in the fridge for up to 3 days.
