    These overnight oats are a creamy and delicious delight. Super easy to prep and pack for an on the go breakfast. Plus they are loaded with a ton of protein to keep you full and satisfied until your next meal!

    I’m a big yogurt girl so naturally these overnight oats are 100% going to sneak some greek yogurt into them to pack an extra hit of protein… and they give this recipe the most satisfyingly creamy consistency. 

    If you’re a chocolate peanut butter fan like me, you’re going to love these overnight oats. It’s almost like a mushy bowl of Reese’s peanut butter cups and an oatmeal cookie… but healthy and for breakfast! If you’re a sweets-loving breakfast person, these overnight oats are definitely for you!

    How long do overnight oats last? Overnight oats are a great meal prep idea. You can make a big batch of these on a Sunday night and they’ll last for the whole week! The longer the oats sit in the fridge however the more time they have to absorb the liquids so by the last day, they will be quite mushy… still very very delicious but just note the consistency and texture will change a bit day to day the longer they are in the fridge. Long story short, you can keep these overnight oats in the fridge for about 5-6 days. 

    How long should I soak the oats? They’re called overnight oats because the flavors and textures are best when left to marinate in the fridge for over 8 hours. However, if you find yourself craving a bowl of cold oats in the morning and you forgot to prepare these the night before, you can get away with letting them soak for 2 hours. This will give the oats enough time to absorb some of the liquids, but they certainly won’t be as absorbed as the overnight ones. The longer the oats are soaking the gooeier and creamier they will be! 

    Let’s get these oats soaking!

    Ingredients in these Chocolate Peanut Butter Protein Overnight Oats

    Old Fashioned Rolled Oats: These oats are best for overnight oat recipes as they absorb the liquids better than steel cut or quick oats would. 

    Chocolate Protein Powder: For an extra hit of protein and that delicious chocolate flavor opt for a chocolate protein powder. Protein powder not your thing? Swap it for cocoa or cacao powder for a similar taste!

    Peanut Butter: Creamy, crunchy, salted, or unsalted peanut butter will work great for these oats, it’s your preference! You can also swap for almond butter or any nut butter you like.

    Almond Milk: I always buy unsweetened plain almond milk but feel free to swap for vanilla or regular dairy milk.

    Greek Yogurt: Adding this to the overnight oats is a sneaky way to pack in extra protein while simultaneously making the creamiest texture. I use plain non-fat greek yogurt, but again use what you prefer fat-wise, flavor wise I would stick with plain or vanilla so the other ingredients aren’t overpowered. 

    Chia & Flax Seeds: The combination of these seeds adds in even more protein, some omega-3 fatty acids, and fiber. The chia seeds will help absorb some of the liquid and give these overnight oats a nice  thick and fluffy consistency. The flax seeds have a mild nutty flavor that will complement nicely with the peanut butter. 

    Honey: A little natural sweetness from the honey really rounds out this recipe.
