Ingredient Notes
The base ingredients for protein baked oatmeal are oats, milk, flax, banana and protein powder. From there you can experiment with add ins like nuts, berries, seeds or chocolate chips.
Here are a few notes on the basic ingredients:
- Oats: I’d recommend large flake or rolled oats but quick oats are also suitable.
- Milk: You can use any unsweetened non-dairy milk like almond milk, cashew milk or soy milk.
- Ground Flax: You can use ground flax seeds or chia seeds for binding since the recipe does not contain eggs. We found flax to produce a firmer, more structured bar but both work well.
- Banana: Use a ripe or slightly overripe banana.
- Protein Powder: Use plant-based vanilla protein powder. Make sure you like the flavour before using as it will contribute to the overall flavour of the bars! You can substitute another protein flavour if you like.
- Extras: Cinnamon, salt and vanilla extract are suggested for flavor but not required.
This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.
Variations & Additions
There are many different ways to make protein baked oatmeal! Here are some ideas to customize the recipe:
- Berries: Fresh or frozen berries of choice are recommended. You can use blueberries, blackberries, raspberries or sliced strawberries. Blueberry banana or strawberry banana is a good combo! Diced apples work well here too.
- Chocolate Chip Baked Oats: Add up to 1/2 cup chocolate chips to the batter.
- Maple Nut: Add 2 tbsp maple syrup and up to 1/2 cup chopped walnuts or pecans.
- Carrot Cake: Add up to 1 cup finely grated carrot to the mixture. A pinch of ginger and nutmeg goes well here and you can consider other add-ins like walnuts, coconut or raisins.
- Dried Fruit: Try raisins, cranberries, chopped apricots, dates or cherries.
- Seeds: Try hemp seeds, sunflower seeds or pumpkin seeds.
- Morning Glory: Add pumpkin seeds, carrot, raisins and walnuts.
- Powdered Peanut Butter: Replace one scoop of the protein powder with 1/3 cup powdered peanut butter for peanut butter protein oats.
- Additional Spices: Cinnamon is recommended but spices like ginger, nutmeg, cardamom and cloves all work well for flavor variations.
How to Make Protein Baked Oatmeal
Step 1. Add the banana to a 7-8 inch square baking dish. Mash with a fork until it resembles a paste.
Step 2. Add the vanilla and plant-based milk and stir to combine.
Step. 3. Add the oats, flax, protein, sea salt and cinnamon to the wet ingredients and stir into a thick mixture.
Step 4. Stir your choice of add-ins such as fresh or frozen berries or chocolate chips into the oat mixture, or leave them plain.
Bake for 30 minutes, let cool in the pan for 20-30 minutes to allow to firm into bars. This isn’t required but the bars will be firmer if you let them cool a while.
Serve with a drizzle of peanut butter, sunflower seed butter or almond butter, Greek yogurt, coconut yogurt, banana, walnuts or any other topping you desire.
You can enjoy them as a snack bar or heated in a bowl with oatmeal toppings like maple syrup, yogurt and more berries.
Expert Tips
- Depending on if you flax or chia, you may find the bars are more or less firm. Either way, if you let them cool in the pan they’ll firm into a solid bar you can eat as a snack. If you don’t mind them a bit more mushy, you can slice from the pan right away.
- If you’re using frozen berries, it’s suggested to sprinkle them over the top of the bars before baking and press them down a bit rather than mix them in.
Recipe FAQs

Are these crunchy?
No, they are not crunchy.
Thank you! Do you have any suggestions for making these into a bar with more of a granola bar consistency? (soft/chewy or a little crunch)
Wow!! So good, just the kind of recipe I was looking for, to use up my vanilla protien powder. Its delicious – thank you!
For the “2 servings of protein powder (60 g)”, do you mean 2 scoops or 4? I’m asking because an orgain protein powder serving size is 2 scoops and equals out to be 46 g. I can’t wait to make this, thanks!
I used 60 grams, so it’s best to go by that amount for accuracy. Thanks!
Easy and excellent source of protein. I increased the cinnamon to 1 tsp, added 3/4 cup apple sauce and increased blueberries to 2 cups.
Yum! I followed this as listed, using frozen blueberries, and it’s delicious! A great way to use my beloved protein powders without pulling out the blender. Thank you for this!!
You’re welcome! Glad you enjoyed!
Love this recipe. Love the health benefits too. Thank you for another great one
This recipe is awesome! Makes for a filling breakfast! I don’t like overnight oats, but have always wanted to find a protein oatmeal recipe- this hits the mark!
So glad to hear that, Nicole! Thanks for the review.
Do you have a go to brand of pea protein – I have used ripple just never a pea protein powder.
Vega, NuZest, PVL, North Coast Naturals, Orgain, PEScience…most vegan protein powders are pea protein-based. Enjoy!
Thank you!
Can I add more scoops of whey protein?
You’d have to adjust the other ingredients if you add more protein. They already contain quite and bit, I wouldn’t suggest adding more. They’ve also not been tested with whey protein and I’m not sure if it would work since it acts different in recipes than pea protein.
How could you substitute protein powder in this recipe? Chia seeds perhaps?
I’m not really sure how to sub the protein in this recipe…but I have a couple other baked oat bars without protein. You can find them by searching oatmeal bars from the home page or looking under snacks. 🙂
