This chocolate protein baked oatmeal can be made TWO ways! You can do a single serving version or a larger version. It’s packed with protein, only sweetened with bananas, and has a dense brownie-like texture. This oatmeal also checks the gluten-free, dairy-free, egg-free box for those that need that! Very minimal ingredients and so delicious!
What is baked oatmeal?
Baked oatmeal is oatmeal baked in the oven making breakfast incredibly easy. You can make it ahead so that all you have to do is warm it in the morning or eat it straight from the fridge (which I often do)! It’s a great simple breakfast or snack option. It tastes like dessert and it’s just so delicious!

What you need to make chocolate protein baked oatmeal + substitutions:
- Quick oats- I love using quick oats, because it gives it the best texture! This is my absolute favorite way to make baked oatmeal, because it makes it dense and brownie-like. You can substitute with rolled oats, which will make it a little more chewy but still fabulous!! Steel cut oats won’t work for this!
- Almond milk- You can definitely substitute with another milk like cashew, soy, oat, dairy or whatever you prefer!
- Banana- The mashed banana gives it a little sweetness as well as making it nice and soft.
- Chocolate protein– I used Nuzest chocolate protein (you can use the lex for 15% off), because I love this one! You can use any protein powder, but mine does add a little sweetness so that’s why I skipped any sweeteners this time. Four scoops measures out to be about 1/2 cup.
- Baking powder- Baking powder helps the oatmeal to rise.
- Cinnamon– I just love cinnamon in any baked recipe. This just adds a nice little touch!
- Vanilla extract- A key to any baked recipe in my opinion.
- Sea salt- I don’t bake anything without salt. It’s what helps bring the flavor out in a recipe.

Tips for making:
- Quick oats vs rolled oats- Like I said above, quick oats will give it a denser, more brownie-like texture and is what I personally prefer. Rolled oats will still work, but they will create a more crumbly texture.
- For the best texture- You want to make sure the chocolate protein baked oatmeal is still soft in the center, but cooked through. That way it comes out nice and soft.
- I don’t think this recipe would work without the protein powder! You could try substituting with something else if you’d like, but I have not tested it. The protein really helps to soak up the liquid and hold everything together! If you’re looking for a baked oatmeal without protein powder, I have a TON of other options!

Is it possible to substitute the banana in this recipe? If so, what would be a good substitute?
Hi Lee Ann! That’s a great question, I haven’t tested myself but I think you could try applesauce, yogurt, or even mashed sweet potato. You may need sweetener unless your protein powder has it 🙂
