Looking for an easy Overnight Oats Recipe With Protein Powder? This simple four-ingredient recipe makes thick, creamy, protein-packed overnight oats that are perfect for meal prepping and busy mornings. The best part is that you can make them with any flavor of protein powder and customize the toppings to suit your taste.

Adding protein powder to overnight oats is an easy way to make a traditional oat-based breakfast more filling while increasing its protein content. It also adds flavor and can help create a thicker, creamier consistency as the oats soak.
The beauty of this recipe is how easy it is to customize. Use vanilla protein powder, chocolate protein powder, strawberry, salted caramel, or any other flavor you enjoy, then add toppings that complement it. You can create a completely different breakfast without changing the base recipe.
These overnight oats get their thick, creamy texture from Greek yogurt and protein powder, so there’s no need for a long list of ingredients or chia seeds. Simply mix everything together, refrigerate overnight, and you’ll have a delicious high protein breakfast ready to enjoy the next morning.

Overnight Oats Recipe With Protein Powder
This Overnight Oats Recipe With Protein Powder is a simple base recipe made with just four ingredients: rolled oats, milk, Greek yogurt, and protein powder. Once you’ve got the base, you can use any flavor of protein powder and add your favorite toppings to create endless combinations.
Rolled oats soften as they absorb the liquid in the refrigerator, while Greek yogurt gives the mixture a thick, creamy consistency and adds extra protein. The amount of milk can also be adjusted slightly depending on the protein powder you use, as different protein powders absorb liquid differently.
For the protein powder, use around 30g, which is typically one scoop. Vanilla protein powder gives you a classic base that works well with fruit and nut butters, while chocolate protein powder is perfect for richer combinations. Strawberry, salted caramel, cookies and cream, and other flavored powders can all work too.
For the milk, use whatever you prefer. Almond milk is a great option, but dairy milk, soy milk, oat milk, or another milk of your choice will work. If you’re making these as part of your meal prepping routine, using the milk you already keep in your fridge makes this recipe even easier.
Unlike many overnight oat recipes, this recipe doesn’t require chia seeds, maple syrup, or vanilla extract. These can all be added if you prefer, but the four basic ingredients are enough to create thick, creamy overnight oats.

Why You’ll Love These Protein Overnight Oats
- Just 4 ingredients: You only need rolled oats, milk, Greek yogurt and protein powder to make the base recipe.
- Any flavor you like: Use your favorite protein powder flavor and switch up the toppings to create a different breakfast every time.
- Thick and creamy: Greek yogurt and protein powder give these overnight oats a rich, creamy texture without needing chia seeds.
- High in protein: Adding protein powder and Greek yogurt makes this a much more protein-packed option than traditional overnight oats.
- Perfect for meal prepping: Prepare several servings at once and keep them in the fridge for an easy grab-and-go breakfast.

How Much Protein Powder To Add To Overnight Oats
For one serving, 30g of protein powder (usually one scoop) is the sweet spot.
Adding too much can make your oats:
- Dry
- Chalky
- Overly thick
- Too strong in flavor
Different protein powders absorb liquid differently, so you may need to adjust the consistency with a splash of milk before serving.
Want more protein? Add a little extra Greek yogurt rather than another scoop of protein powder to keep the oats creamy.

How To Add Protein Powder To Overnight Oats
The easiest way is to add the protein powder directly to the jar with the other ingredients and stir well. If your protein powder tends to clump, try one of these methods:
Add It Directly To The Oats
Add everything to your jar and stir thoroughly, making sure to scrape around the bottom and sides. This is the method I use for this recipe and requires no extra dishes.
Mix It With The Liquid First
Whisk the protein powder and milk together until smooth, then add the mixture to your oats and Greek yogurt.
Make A Protein Slurry
For particularly stubborn protein powder, mix it with a small amount of milk first to form a smooth paste. Gradually add the remaining milk, then combine with the oats and yogurt.
For this recipe, simply mixing everything together works well for most protein powders.

How To Make Overnight Oats With Protein Powder
Making overnight oats with protein powder couldn’t be easier. Simply combine the rolled oats, milk, Greek yogurt and protein powder in a jar or container, stir until smooth, and refrigerate overnight.
Because protein powders vary in how much liquid they absorb, your oats may be thicker or thinner depending on the brand you use. I recommend checking them in the morning and adding a splash of milk if needed to reach your preferred consistency.
Ingredients
- Rolled oats: These are the base of the overnight oats. I recommend using rolled oats rather than quick oats because they soften overnight while still keeping a little texture.
- Milk: Milk provides the liquid the oats need to soften and creates a creamy consistency. You can use any milk you like, including almond milk, dairy milk, soy milk, or oat milk.
- Greek yogurt: Greek yogurt is the secret to making these overnight oats extra thick and creamy. It also adds extra protein, helping turn this into a more filling high protein breakfast.
- Protein powder: Use around 30g (usually one scoop) of your favorite protein powder. You can use any flavor you like, from vanilla protein powder and chocolate protein powder to strawberry, salted caramel, or unflavored. The protein powder adds flavor, sweetness, and a boost of protein to the oats.

Optional Add-Ins
These aren’t necessary for the recipe, but you can add them depending on your taste and preferred texture:
- Chia seeds: Add 1–2 teaspoons if you like particularly thick overnight oats or want to add extra fiber. Unlike many overnight oat recipes, chia seeds aren’t needed to thicken this recipe.
- Maple syrup: Add a little maple syrup if you prefer sweeter overnight oats or your protein powder isn’t very sweet.
- Vanilla extract: A splash of vanilla extract can add extra flavor, particularly when using vanilla or unflavored protein powder.
Instructions
Step 1: Combine the ingredients.
Add the rolled oats, milk, Greek yogurt and protein powder to a bowl, mason jar or airtight container.

Step 2: Mix until smooth.
Stir everything together thoroughly until the protein powder has been fully incorporated and there are no dry pockets remaining. You can also mix in some fruits, nuts, seeds, etc.



Step 3: Refrigerate.
Cover the jar and refrigerate for at least 4 hours, but preferably overnight. This gives the oats enough time to soften and absorb the liquid.
Step 4: Stir and serve.
The next morning, give your overnight oats a good stir. If they’re thicker than you’d like, mix in a splash of milk. Add your favorite toppings and enjoy!
Tips For Making The Best Protein Overnight Oats
- Use rolled oats: They soften overnight while keeping some texture, unlike quick oats which can become mushy.
- Use a protein powder you enjoy: The flavor will come through in the finished oats, so choose one you actually like.
- Don’t overdo the protein powder: Around 30g per serving gives you a good balance of protein and texture.
- Let them soak overnight: At least 4 hours works, but overnight gives the best texture.
- Adjust before serving: Too thick? Stir in a splash of milk.
- Add crunchy toppings last: Add granola, nuts and other crunchy toppings just before eating so they don’t become soggy.

Build Your Own Protein Overnight Oats
The base recipe stays the same – just choose your protein powder and toppings to create a completely different flavor.
- Banoffee Pie: Caramel protein powder + sliced banana + peanut butter + crushed biscuits
- Chocolate Peanut Butter: Chocolate protein powder + peanut butter + banana + dark chocolate chips
- Strawberries & Cream: Vanilla or strawberry protein powder + fresh strawberries + Greek yogurt + freeze-dried strawberries
- Blueberry Cheesecake: Vanilla protein powder + blueberries + Greek yogurt + granola or crushed biscuits
- Apple Pie: Vanilla protein powder + diced apple + cinnamon + almond butter + walnuts
- Tiramisu: Vanilla protein powder + coffee + cocoa powder + Greek yogurt
- Mix and match your favorite flavors and toppings to create your own combination!

How Long Can You Keep Overnight Oats With Protein Powder?
Fridge: Store your overnight oats in an airtight container or mason jar in the refrigerator for up to 4 days. The oats will continue to soften and thicken the longer they sit, so you may want to add a splash of milk before serving if they become too thick.
Freeze: I don’t recommend freezing these overnight oats. The Greek yogurt can change texture when frozen and thawed, which can make the oats less creamy.
Meal-Prep: These overnight oats are perfect for meal prepping! Prepare several servings at once and store them in individual jars in the fridge for an easy grab-and-go breakfast throughout the week. Add fresh toppings just before serving for the best texture.
