This vegan baked berry protein oatmeal is super easy to whip up for a make-ahead breakfast.

Baked oatmeal topped with berries on a plate with a spoon, two additional plates in background.

About the Recipe

This recipe is made all in one dish so it’s very easy and fuss-free to prepare. The oats are vegan, gluten-free, nut-free and soy-free and have no added sugar.

They’re also low in fat, high protein and a source of dietary fiber. They contain 10 grams of protein per bar but you could easily have two as they’re quite low calorie. Make these ahead of time for a quick breakfast and easy snack.

For a variation, these Vegan Chocolate Baked Oatmeal Bars are also made with protein powder or you can try these Easy Vegan Banana Baked Oatmeal or Apple Cinnamon Baked Oatmeal or Carrot Cake Baked Oatmeal for baked oats without protein.

Ingredient Notes

  • Oats: I’d recommend large flake or rolled oats but quick oats are also suitable.
  • Milk: I’d recommend a fairly light milk like almond or cashew, it shouldn’t be too thick or heavy.
  • Ground Flax: Can be subbed with chia seeds but I find flax works best here.
  • 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!
  • Berries: Any fresh or frozen berry works, if using strawberries or cherries, I’d suggest chopping them up first

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.

Step-by-Step Instructions

Step 1. Add the banana to a 7-8 inch square baking dish. Mash with a fork until it resembles a paste.

Step 4. Sprinkle the berries evenly over the top of the mixture, pressing them in a bit with your fingers or a spoon. If you’d like to add anything like chocolate chips or walnuts, you can either mix them in or sprinkle them on top as well.

Bake for 30 minutes, let sit for 5 minutes then slice into bars and enjoy! Serve with a drizzle of your favourite nut butter, 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.

  • 2 scoops vanilla pea protein-based protein powder , 60 g
  • 1 tbsp ground flaxseed, 7 g

Notes

    Serving Size: I cut these into 8 bars but if you’d like them a little bigger, 6 larger bars works too!
    Toppings: Serve with a drizzle of your favourite nut butter, coconut yogurt, banana, walnuts or any other topping you desire.
    Texture: Due to the protein powder, the bars have somewhat of a cakey texture. Just FYI!
    Flavour: Be sure to use a milk and protein powder you enjoy as they will contribute to the final flavour of the bars.
    Storing: Let cool them store in a sealed container in the fridge for up to 5 days or freezer for up to 3 months. If frozen, thaw overnight in the fridge or in the microwave. Bars can be enjoyed cold or reheated in the oven or microwave until heated to your preference.

        Wow!! So good, just the kind of recipe I was looking for, to use up my vanilla protien powder. Its delicious – thank you!

      2. For the โ€œ2 servings of protein powder (60 g)โ€, do you mean 2 scoops or 4? Iโ€™m asking because an orgain protein powder serving size is 2 scoops and equals out to be 46 g. I canโ€™t wait to make this, thanks!ย

        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! ย I followed this as listed, using frozen blueberries, and itโ€™s delicious! ย A great way to use my beloved protein powders without pulling out the blender. ย Thank you for this!!

        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!

        1. Vega, NuZest, PVL, North Coast Naturals, Orgain, PEScience…most vegan protein powders are pea protein-based. Enjoy!

        1. 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.

        1. 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. ๐Ÿ™‚
