Here’s how I make my protein powder overnight oats, for a creamy, healthy, and clump-free breakfast.

Overnight Oats with Protein Powder
I always cook protein pancakes on weekends, so adding protein powder to my overnight oats for a nutritious breakfast on busy weekdays is a no-brainer.
I keep a big container of vanilla protein powder in my pantry, so that’s what I’m using for this recipe. Any flavor will work, but if you have and love chocolate, check out my chocolate protein overnight oats recipe.
Ingredients
You’ll need plant or whey protein powder, any milk, old-fashioned oats, and plain or flavored yogurt. You can add chia seeds and fruit for extra nutrition. For the best consistency, keep the liquid-to-oats ratio at 1:1, meaning ½ cup of milk for each ½ cup of overnight oats.
Best Protein Powder to Use
Both plant and whey protein powders work in this recipe, so you can use your favorite; just keep in mind that whey protein mixes best, and that plant protein yields a thicker, denser overnight oat mixture, which might need a tablespoon or two more milk.
How to Make Protein Overnight Oats
- Mix the protein powder with the milk in a shaker bottle to avoid powdery protein clumps.
- Combine the oats with chia seeds (if using), yogurt, and the protein mixture in a bowl or individual jars. If including fruit, add it now or before serving.
- Refrigerate for at least 4 hours or overnight.
- Enjoy cold or microwave for a few seconds and top with your favorite oatmeal toppings. I like nuts (almonds, walnuts, and cashews), sunflower and pumpkin seeds, hemp hearts, fresh fruit, and nut butter.
More Ways to Add Protein to Overnight Oatmeal
To add extra protein to your oatmeal, make these overnight oats with Greek instead of regular yogurt, or swap for cottage cheese.
Protein Powder Overnight Oats (25g protein)

Ingredients
- ½ scoop protein powder
- ½ cup milk, any
- ½ cup old-fashioned oats
- 1 ½ teaspoons chia seeds, optional
- ½ yogurt, plain or flavored
- ½ cup fruit
Instructions
Combine:
- Mix the protein powder with the milk in a shaker bottle first. This helps you avoid powdery protein clumps.
- Place the oats in a jar or bowl. Add chia seeds (or flax meal) to the oats, if using. Add the yogurt and pour the mixed protein into the bowl. If adding fruit, add it now or before serving. Mix well.
Refrigerate:
- Refrigerate for at least 4 hours or overnight.
Serve:
- In the morning, enjoy cold or warmed up for 30 to 60 seconds in the microwave, topped with your favorite toppings.
Notes
- The thickness (in consistency) of the overnight oats will vary depending on the type of protein powder used. Plant protein powders tend to yield a thicker mixture than whey protein and might need a tablespoon or two more liquid.
- Greek yogurt or regular can be used, with Greek yogurt providing more protein and a creamier texture.
- Macros will vary depending on the milk, protein powder, and yogurt used.
- Nuts or seeds: opt for unsalted raw chopped nuts & seeds.
- Fruit: both fresh and frozen fruit work. Can be added to the oats or on top. Bigger fruits should be sliced.
- Nut butters: peanut butter, almond butter, and seed butters are great for topping or added into the mixture. You can also add 1-2 tablespoons of PB powder.
- Spices: ¼ teaspoon per serving of cinnamon or pumpkin pie spice works great. Vanilla extract (¼ teaspoon) will be delicious too.
- Granola: as a topping.
