If you’ve been around here for a while you know how much I love overnight oats. They are my go-to summer breakfast because they are so easy to make, and you can mix and match the ingredients and toppings to make so many different flavors.

These chocolate protein blended overnight oats are a twist on my protein overnight oats, and they are just as high in protein and fiber. The best part about this recipe is that you can make multiple batches in a large blender in minutes and then divide them across small jars, store them in the fridge, and enjoy high-protein, grab-and-go breakfast for days to come.

Ingredients for high-protein blended overnight oats; rolled oats, chocolate protein powder, cocoa powder, milk, Greek yogurt, and chia seeds.

Ingredients + Substitutions

Oats – I used old-fashioned rolled oats in my recipes, however, you could use quick-cooking oats if preferred. Steel-cut oats are not recommended.
Protein Powder – To add a boost of protein to the blended oats. I recommend using chocolate protein powder, preferably whey protein powder, however, a plant-based protein powder or vanilla protein powder will also work.
Cocoa Powder – To ensure the oats are nice and chocolatey. You can use regular cocoa powder or cacao powder.
Chia Seeds – To add some fiber, and healthy fats, and ensure the blended overnight oats are rich and creamy.
Greek Yogurt – To thicken the oats and add more protein. I recommend Greek yogurt over regular yogurt because it’s higher in protein, but any plain or vanilla yogurt will work.
Milk – To add more protein and healthy fats. I used 2% milk, but you could use almond milk, coconut milk, soy milk, or oat milk if preferred, however, the recipe will be lower in protein.
Berries – To add some fiber to the oats. I served mine with fresh strawberries, but raspberries and blueberries would also work well, you can truly serve them with any frozen or fresh fruit you enjoy.
