Chunky Monkey Protein Overnight Oats

Featured in: Vegetarian Favorites

These Chunky Monkey inspired overnight oats combine the classic trio of banana, chocolate, and peanut butter into a protein-packed breakfast. The mashed banana creates natural sweetness while Greek yogurt and protein powder deliver 27 grams of protein per serving. Chia seeds thicken the texture and add omega-3s, while cocoa powder provides deep chocolate flavor without excess sugar.

Simply mix everything together the night before, refrigerate, and wake up to a ready-to-eat breakfast that tastes like dessert but fuels your body. The oats soften beautifully as they chill, creating a pudding-like consistency that's perfect for busy mornings.

There's something almost magical about waking up to breakfast that's already waiting for you, especially when it tastes like dessert disguised as nutrition. My roommate swore by overnight oats but dismissed them as boring until I showed her this version—banana, chocolate, and peanut butter swirled together the night before. She made it once, and suddenly she was prepping mason jars like they were going out of style. That's when I realized this wasn't just convenient; it was genuinely craveable.

I made this for my partner on a busy Wednesday morning, and watching them spoon into it straight from the fridge with genuine surprise on their face—like they couldn't believe something this good was hiding in there—made me understand why overnight oats have such devoted fans. They asked for the recipe immediately, which never happens.

Ingredients

  • Old-fashioned rolled oats (1 cup): These hold their structure overnight without turning mushy, unlike quick oats, and they create that satisfying chew you actually want to bite through.
  • Unsweetened almond milk (1 cup): Use what you love drinking—I've tried oat milk, coconut, regular dairy—and each one shifts the flavor slightly without ruining the balance.
  • Plain Greek yogurt (1/2 cup): This is your secret weapon for creaminess and protein without any tang taking over the show.
  • Ripe banana, mashed (1 small): The ripeness matters because you want natural sweetness and that silky texture it brings when broken down.
  • Chia seeds (2 tablespoons): They absorb liquid overnight and add a subtle texture that keeps things interesting.
  • Chocolate protein powder (2 scoops): Pick one you actually enjoy tasting plain, because there's nowhere to hide inferior quality here.
  • Unsweetened cocoa powder (2 tablespoons): This deepens the chocolate flavor beyond just relying on the protein powder alone.
  • Natural peanut butter (2 tablespoons): Creamy or chunky both work, but make sure it's the kind with minimal added sugar so you control the sweetness yourself.
  • Maple syrup or honey (1–2 tablespoons): Start with one tablespoon and taste before adding more—you might find the banana and peanut butter give you enough sweetness already.
  • Vanilla extract (1/4 teaspoon): This small amount rounds out all the big flavors without announcing itself.
  • Salt (pinch): Don't skip this; it makes the chocolate sing.
  • Chopped walnuts (1/4 cup): These stay crunchy even after sitting in milk overnight, which is crucial for texture contrast.
  • Mini dark chocolate chips (1/4 cup): They soften slightly but don't dissolve completely, so you get little chocolate bursts as you eat.

Gather and combine your base:
Pour the oats into a mixing bowl, then add the almond milk, Greek yogurt, mashed banana, and chia seeds. Stir everything together until the banana is fully incorporated and there are no dry oat pockets hiding at the bottom—this only takes a minute or two.
Layer in the chocolate and protein:
Sprinkle the chocolate protein powder and cocoa powder over the mixture, then dollop in the peanut butter. Add the maple syrup, vanilla, and salt, stirring until you have a thick, cohesive mixture with no powder streaks remaining.
Fold in your texture:
Gently fold in the walnuts and chocolate chips so they're distributed throughout rather than sinking to the bottom.
Divide and refrigerate:
Split the mixture between two jars or containers, cover them tightly, and place them in the refrigerator for at least 6 hours, ideally overnight. The oats will continue absorbing liquid and the flavors will deepen as everything sits together.
Finish and serve:
In the morning, give the oats a good stir and add a small splash of milk if they've thickened more than you'd like. Top with banana slices, extra walnuts, or chocolate chips and eat straight from the jar if you're feeling lazy (which is completely valid).

My friend who used to grab drive-through breakfast sandwiches every single morning started making these on Sundays, and suddenly she had five jars lined up in her fridge like little edible promises to herself. There's something about having breakfast already made that changes your whole morning mood—you move slower, sit longer, actually taste what you're eating.

Customizing Your Bowl

The beauty of overnight oats is that once you nail the base formula, you can play around without breaking anything. I've made versions with almond butter instead of peanut, swapped the chocolate for vanilla and added berries, even tried cinnamon with a drizzle of molasses when I was feeling adventurous. The Greek yogurt and chia seeds are doing the heavy lifting in terms of texture and satiety, so you can confidently swap out the flavor components without losing what makes this work.

The Overnight Wait Is Not Wasted Time

I used to make these in the morning thinking I'd just eat them after they sat for ten minutes, but I learned quickly that's not how this works. The oats genuinely need time to soften and for all the flavors to meld together—it's not just a texture thing, it's that the chocolate and peanut butter flavor actually develops and deepens as it sits. Making them at night means you wake up to something that tastes intentional rather than rushed.

Storage and Meal Prep Reality

These keep for three days in the fridge, which means if you make a double batch on Sunday, you've got breakfasts sorted through Tuesday morning. I learned this the hard way by making them daily until I realized I was doing unnecessary work when I could have made three containers at once.

  • Store them in glass jars or clear containers so you can actually see what you have and feel motivated to eat them.
  • Keep a small bottle of milk in the fridge next to your oats so you can adjust the consistency right before eating without thinking about it.
  • If you're making these for grab-and-go mornings, eat them straight from the jar with a spoon—no dishes required.

This breakfast works because it doesn't feel like you're being virtuous—it tastes like something you chose because it's delicious, and the protein and nutrients just happen to be along for the ride. Make it once and you'll understand why my roommate now judges me if I try to eat anything else in the morning.

Recipe Q&A

Can I use different milk alternatives?

Yes, any milk works well here. Try oat milk for extra creaminess, coconut milk for richness, or dairy milk if you prefer. Just keep the ratio the same—1 cup of liquid to 1 cup of oats.

How long do these oats last in the refrigerator?

These stay fresh for up to 3 days when stored in airtight containers. The oats actually taste better on day two as the flavors continue to develop and meld together.

Can I make this vegan?

Absolutely. Swap Greek yogurt for coconut yogurt or almond yogurt, use plant-based protein powder, and choose dairy-free chocolate chips. The texture and flavor remain just as delicious.

Do I need to cook the oats?

No cooking required. The oats soften and absorb the liquid while chilling in the refrigerator overnight. This method preserves more nutrients and creates a creamy, pudding-like texture.

Can I reduce the sweetness?

The ripe banana provides natural sweetness, so you can reduce or omit the maple syrup entirely. Taste the mixture before chilling and adjust to your preference—start with 1 tablespoon and add more if needed.
