High Protein Chocolate Peanut Butter Overnight Oats

I have a serious soft spot for breakfasts that taste like dessert but secretly pack in a ton of nutrition, and these High Protein Chocolate Peanut Butter Overnight Oats are exactly that. They’re thick, creamy, and loaded with deep cocoa flavor, with just enough peanut butter to make every spoonful feel indulgent.

The best part? I can stir everything together in just a few minutes at night, pop the jars in the fridge, and wake up to a cold, chocolatey breakfast that keeps me full for hours. If you love easy meal prep, high protein breakfast ideas, or anything chocolate and peanut butter, this one’s going to be on repeat.

Are High Protein Chocolate Peanut Butter Overnight Oats Really Filling?

Yes, absolutely. Between the rolled oats, Greek yogurt, chia seeds, peanut butter, and a scoop of protein powder, these overnight oats are designed to be a satisfying, stick-to-your-ribs kind of breakfast. I love grabbing a jar when I know I have a busy morning ahead because the combo of protein, healthy fats, and fiber keeps my energy stable instead of giving me that mid-morning crash.

If you’ve ever felt like a bowl of regular oatmeal just doesn’t hold you over, this version might change your mind. It’s more like a thick chocolate pudding with oats tucked inside, and it genuinely eats like a meal.

Ingredients for High Protein Chocolate Peanut Butter Overnight Oats

Before you start mixing, here’s a quick rundown of what goes into these jars. I don’t use anything fancy here—just a handful of pantry staples that work together to create the creamiest, most chocolatey oats.

• Rolled oats – Old-fashioned rolled oats give the best chewy-but-soft texture after soaking overnight.
• Chia seeds – These tiny seeds help thicken the oats and add extra fiber, omega-3s, and a little protein.
• Unsweetened cocoa powder – For that rich chocolate flavor without adding extra sugar.
• Chocolate or vanilla protein powder – The main protein boost that makes these oats so filling and satisfying.
• Plain Greek yogurt – Adds creaminess and tang while upping the protein even more.
• Creamy peanut butter – Brings in healthy fats, flavor, and that classic chocolate–peanut butter combo.
• Milk of choice – You can use dairy milk, almond milk, oat milk, or whatever you love to loosen the mixture and help the oats soften.
• Maple syrup or honey – A touch of natural sweetness to balance the cocoa.
• Vanilla extract – Rounds out the chocolate flavor and makes everything taste bakery-level good.
• Fine sea salt – Just a pinch to deepen the chocolate and keep the flavor from tasting flat.
• Mini chocolate chips (optional) – For sprinkling on top when you’re ready to serve, because a little extra chocolate never hurts.

How To Make the High Protein Chocolate Peanut Butter Overnight Oats

Once you’ve gathered your ingredients, the rest is basically a stir-and-chill situation. I like to mix everything in one bowl and then portion it out into jars for grab-and-go breakfasts.

Step 1: Combine the dry ingredients

In a medium mixing bowl, stir together the rolled oats, chia seeds, unsweetened cocoa powder, protein powder, and a small pinch of salt. Make sure everything is evenly mixed so you don’t end up with any clumps of cocoa or protein powder later.

Step 2: Whisk the wet ingredients

In a separate bowl or large measuring cup, whisk the milk, Greek yogurt, peanut butter, maple syrup, and vanilla extract. Keep whisking until the mixture looks mostly smooth and the peanut butter is well incorporated.

Step 3: Bring the oats together

Pour the wet mixture over the dry ingredients. Use a spatula or spoon to slowly fold everything together until you no longer see any dry spots. The mixture will look a little loose at this point, but remember the oats and chia seeds will thicken it as they soak.

Step 4: Taste and adjust

Give the mixture a quick taste. If you like sweeter oats, you can add a little extra maple syrup. If it’s already quite thick, splash in a bit more milk so it stays creamy after chilling.

Step 5: Portion into jars

Divide the mixture evenly between two glass jars or airtight containers. I like to leave a bit of space at the top of each jar for stirring and toppings in the morning.

Step 6: Chill overnight

Seal the jars and refrigerate for at least 4 hours, but overnight is ideal. During this time the oats and chia seeds absorb the liquid and the mixture turns into a thick, spoonable pudding.

Step 7: Stir, top, and enjoy

In the morning, give each jar a good stir. If the oats seem too thick for your liking, loosen them with a splash of milk. Finish with a sprinkle of mini chocolate chips and an extra drizzle of peanut butter or sliced banana if you’re feeling fancy.

How to Serve and Store These Overnight Oats

I usually enjoy these oats straight from the jar, cold from the fridge. If you prefer a warmer breakfast, you can microwave the jar (as long as it’s microwave-safe) in 20–30 second bursts, stirring in between until it’s just warm.

For extra texture and freshness, I love adding sliced banana, strawberries, or a handful of raspberries on top. A sprinkle of granola is also amazing if you like a bit of crunch with your creamy oats.

These overnight oats keep well in the fridge for up to 4 days, which makes them perfect for meal prep. If you’re planning to store them that long, I recommend leaving fresh fruit and crunchy toppings off until you’re ready to eat. Just grab a jar, add your favorite toppings, and breakfast is ready in under a minute.

What to Serve With High Protein Chocolate Peanut Butter Overnight Oats?

If you want to round out this breakfast or turn it into a brunch spread, here are a few ideas that pair really nicely with the chocolate and peanut butter flavors.

Fresh berries or sliced fruit

A bowl of fresh berries, sliced banana, or crisp apple wedges adds natural sweetness and a refreshing contrast to the rich oats.

Turkey sausage or chicken sausage

If you like a savory side with your sweet breakfast, a couple of turkey or chicken sausage links bring even more protein and balance out the meal.

Hard-boiled or scrambled eggs

Eggs are always a classic breakfast partner. I’ll sometimes pair a jar of these oats with one or two hard-boiled eggs for an ultra-filling morning.

A simple smoothie

Blend up a quick green smoothie or fruit smoothie to sip alongside your oats if you’re extra hungry or heading into a long morning.

Hot coffee or a homemade latte

A creamy latte or a strong cup of coffee is the perfect match for anything chocolate and peanut butter. I love dunking my spoonful of oats between sips.
