Baked Protein Oats
My blueberry baked oatmeal is a favorite in my house, so I decided to add a protein boost. I already use vanilla protein powder for protein pancakes and cookies, and now, baked protein oatmeal!
With this quick recipe, you can enjoy an epic morning meal with the health benefits of oats, added nutrition from protein powder, and the deliciousness of fruit.
Ingredients
This recipe calls for milk (regular or non-dairy), eggs to help the batter rise and bind the ingredients, honey, butter or coconut oil, vanilla extract, old-fashioned oats (the kind of oat that holds its texture better in the oven), vanilla protein powder, salt, and your favorite mix of berries.
Best Protein to Use for Baked Oatmeal
The best protein powder is the one you like the most to give this oatmeal a tasty flavor your family loves. My favorite for this recipe is vanilla protein, and I use both whey and plant-based, depending on what I have on hand!

Then, add the berries on top. If some berries sink, that's perfectly fine! - Bake for 35 minutes.

Allow baked protein oats to cool down for a few minutes before serving so the oatmeal is set.

Laura’s Tips for Protein Baked Oatmeal
Using quick-cooking oats (instant) when making this baked oatmeal without adjusting the liquid will yield a softer, sometimes gooier baked oatmeal.
When baked to 375F, this protein oatmeal is ready after 35 minutes, but not all ovens are the same! You’ll know baked oatmeal is done when the center is no longer wet and you see the oat mixture has set.
Whether you make this recipe ahead or have leftovers, baked protein oats can be refrigerated for up to 4 days. Reheat in the microwave for about one minute, adding a little milk if you want your oats a little less thicker.
Flavor Mix-Ins for Protein Baked Oats
You can stir these mix-ins into the batter for extra flavor:
- Chocolate chips
- Brown sugar
- Cinnamon
- Dried cranberries
- Blueberries
- Sliced strawberries
- Sliced banana
- Diced pears
- Diced apples

Protein Baked Oatmeal

Ingredients
- 2 cups milk, any
- 2 eggs
- 2 tablespoons honey
- 1 tablespoon butter or coconut oil, melted
- 1 teaspoon vanilla
- 2 cups old-fashioned oats
- ½ cup vanilla protein powder
- ½ teaspoon salt
- 1 cup berries, your favorite
Instructions
Prep:
- Preheat the oven to 375F and spray an 8-inch or 9-inch baking dish.
- In a large bowl, combine the milk, eggs, honey, butter, and vanilla. Add the protein powder and mix. Add the oats and salt and combine the mixture into a thick batter. Combining the ingredients in this order ensures the even distribution and absorption of the protein powder.
- Pour the oat batter into the prepared baking dish. Distribute the berries on top. Some will sink during baking, that's ok!

Serve:
- Once the baked oatmeal has cooled down for 5 minutes, slice a square or spoon some of it into a plate. Serve topped with yogurt, additional berries, or a drizzle of nut butter.
