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
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!).

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.

How To Make Peanut Butter Overnight Oat
- 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.
- Mix everything well until the peanut butter is fully blended.
- Cover and refrigerate overnight or for a minimum of 30 minutes to allow the oats to thicken.
- 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.

These are sooo good. Making this for the third time and I’m already excited to eat it! Once I subbed in chocolate soy milk and that was delicious. Love this recipe!
That’s so great to hear!! Thanks for taking the time to comment Mary! And chocolate soy milk sounds amazing!
This was delicious! I added a baby banana to mine and used 2T reduced fat peanut butter. Thanks for the recipe!
Those are great additions/substitutions! I’ll have to try that next time 🙂 Thanks so much for taking the time to comment!
Ohhh my, this looks so delicious!! It incorporates many of my favorite things!! So happy to have found you!! <3 Abigail
Oh thank you so much Abigail! 🙂
I tried this this morning and it was out of this world! I think it might be good with toasted walnuts, too, but it would have a higher calorie count, of course. Thanks for posting it!!
So glad you tried it and thank you for taking the time to comment! Also love the idea of toasted walnuts – definitely need to try that 🙂
This does look really good. But When I calculated the calories it was quite a bit higher. It would be 338 for 1/2 of yours as written. If you add 1 Tbsp of maple syrup and 1 tsp of chocolate chips it would be 407. So if someone at the whole recipe we’re talking 814 calories.
I agree, I meal prep overnight oats every night and I calorie count. The calories are way off. Just the 2-1/2 tbl of peanut butter is around close to 210 cals.
Nutrition is per serving; there are 2 servings calculated for this recipe; hope that helps!
So, originally I came here for this recipe over from the In and Out of the Kitchen Link Up Party. But honestly, I have already been sending friends and family members links to other recipes and I am drooling at the moment. You have made me so hungry, cannot wait to try a few of your recipes out, especially the pizookie, my sister and I have some major plans for that one 🙂
Thank you so much Jilly! And thanks for sending out some of my links – that’s so great of you! 🙂 I hope you two enjoy the pizookie, have a good one!
This looks amazing! I love overnight oats so much!
Overnight oats are the best! Thanks Claudia 🙂
