Cake Batter Baked Oatmeal Without Eggs or Milk

This oatmeal recipe uses absolutely no eggs or regular milk! Just like in my Matcha Latte recipe, we use plant based milk as listed above. Feel free to use any milk you have on hand though! And even if you don’t have milk, you can sub with good ole’ H2O (water). The oats and protein powder make this oatmeal bake soft, chewy, and slightly fluffy without having to add any eggs.

How to Make Vegan Funfetti Baked Oats

As I just said above, you don’t need any eggs or flax eggs for this baked oatmeal recipe. It’s completely vegan and plant based. The beauty of this oatmeal recipe is that you can use whatever protein powder or milk you have on hand! Even if you don’t have milk, you can sub it for all water. That’s how easy and simple it is!

This high protein baked oatmeal recipe is made with my very favorite vegan vanilla protein powder. I use this protein powder in my Matcha Overnight Oats too. And if you’re looking for more great vegan breakfast options, check out these 12 Easy Vegan Protein Breakfasts!

Funfetti Cake Batter Baked Oatmeal (Secretly Healthy)

Funfetti Cake Batter Baked Oatmeal

This Funfetti Cake Batter Baked Oatmeal is soft and loaded with birthday cake flavor! You would never know it’s secretly healthy, packed with protein, vegan, and gluten-free! You only need the baking dish to make it!

Prep Time 5 minutes
Cook Time 35 minutes
Total Time 40 minutes


  • 2 Medium Overripe Bananas (1 Cup Mashed Banana) (See Note 4 for substitutions)
  • 2 Cups Rolled Oats (can sub quick cooking)
  • 2 Scoops (about ½ Cup) Vanilla Plant Based Protein Powder (See Note 3 for Sub Options)
  • 1 Cup Plant Based Milk (or Milk of Choice) + 1¼ Cup Water 
  • 1½ tsp Almond Extract
  • 1 tsp Vanilla Extract
  • ¼ Cup Naturally Colored Sprinkles (I use this brand)
  • Opt: Dash Pink Salt


1. Preheat the oven to 350 F.

2. In a 2 quart baking pan mash the banana with the back of a fork. Add all other ingredients except sprinkles into baking dish and stir until mixture is combined.

3. Gently stir in sprinkles. Place in the oven to bake at 350 F. for 35-40 minutes until golden brown.

4. Let baked oatmeal cool for a few minutes or until set and serve with cashew butter, protein cream cheese icing, fresh berries, banana slices, or your favorite milk! 

5. Store in the fridge for up to a week and enjoy a premade healthy breakfast all week long!


  1. Liquid: You can use any liquid of choice for this recipe. I use a combination of plain unsweetened almond milk and water to make the oats thick and creamy. You can swap the milk for all water or do a different combination. I have found that this combo works perfectly though!
  2. Most oats are gluten-free, just make sure by checking the packaging! I love this brand.
  3. Any plant based protein powder works! If you’re using unflavored or unsweetened protein powder, I suggest adding honey or maple syrup to taste. I DON'T recommend using whey protein powder because it can cause a chewy, almost crispy texture. I've had people use whey that love it still, but personally, I would avoid whey for these texture reasons.
  4. Don’t have bananas? You can sub the banana with ½ Cup of your favorite yogurt or 3/4 Cup Unsweetened Apple Sauce.

    This recipe is so so so good! I’ve made it 2 times now! The first time I used brown rice protein powder and the second time I used the usual Trader Joe’s protein powder I keep on hand and it is so yummy both ways. I love the texture and having it with berries in the morning, or even as dessert with some protein cream cheese frosting! Can’t recommend this enough, makes mornings so much quicker when I prep this on Sunday and munch the whole week.

    • Claire

      AMAZING! This one is also one of my favorites! I’m so glad you love it so much! I totally agree that it makes the weekday breakfasts a breeeeeze and you don’t even have to think about it 🙂 Yay!

    • Willow Wood

      Are the bananas a necessary binding agent or just for flavor/texture? Imballergic

      • Claire

        The bananas are the base of the baked oatmeal, but you can substitute them for 1 cup unsweetened applesauce. Let me know how you like this baked oatmeal! It’s one of my favorite flavors 🙂

  • Debra Morrow

    I made this with your applesauce substitution and WOW. This is incredible! I didn’t think that oats could be low calories and taste like cake–you’ve proved me wrong! This is absolutely delicious and I can’t wait for my husband to try it too!

    • Claire

      Hi Debra! I am so glad you made this baked oatmeal flavor. It’s one of my personal favorites too. So glad you enjoyed it! Thanks for sharing your success 🙂 Happy healthy baking!

  • Grace Gibney

    Hi Claire! This recipe looks so delicious! Do you have a recommendation for substituting something for the protein powder? I am not able to have protein powder at this point in time and would love to hear other suggestions you have for it.



    • Claire

      Hi Grace! I would say sub the protein powder for more oats and also add more sweetener to taste. :)The vanilla protein powder is what helps it taste more like “birthday cake” so you could also add more vanilla and almond extract “to taste” when preparing it. Hope it turns out well and I hope you enjoy it! Let me know 🙂

  • nicole lien

    Hi this recipe looks delicious but i have a few questions. It says it yields 9 pieces so is it 151 per piece? do u possibly have a reduced ingredient size for just one serving of this? Also i dont have protein powder so can i just use less liquid? I also dont have almond extract should i add extra vanilla extract? Thank you!!

    • Claire

      Hi there! Yes, it’s 151 calories per piece (with some variance depending on the protein powder or ingredients you use). If you’re trying to make it single serve I would suggest using 1/4 of the whole recipe and baking it a little shorter probably (20-30 mint). The vanilla protein powder is what gives it that “vanilla cake” flavor, so if you don’t have that I would suggest adding a lot more sweetener. The liquid measurement should stay the same. I do have other baked oatmeal recipes that call for unflavored protein powder and for those recipes it’s much easier to leave out the protein powder completely. So maybe try out my pumpkin chocolate chip baked oatmeal or apple pie baked oatmeal 🙂 Protein powder for this one is kind of vital and I would hate for it to turn out badly for you if you made it without the protein powder and didn’t enjoy it.

      I hope that helps! Let me know if there’s anything else I can help with!
