I’m definitely on a baked oatmeal kick. It all started with my Chocolate Chip Cookie Baked Oatmeal. When something tastes like a cookie and you can eat it for breakfast, how can you say no?! What I love about this Chunky Monkey flavor is the peanut butter! If you’re nut butter obsessed, like myself, then you have to try this chunky monkey baked oatmeal recipe!

Easiest Baked Oatmeal EVER!

Just when you thought baked oatmeal couldn’t get any easier, I found a way! Here are the steps to making the easiest and yummiest baked oatmeal! All you need is the baking dish and a fork!

  1. Get out a 2-quart baking dish (here is the exact one I use).
  1. Using the back of a fork, mash the ripe bananas right in the baking dish.
  1. Add in all other ingredients and stir it up!
  1. Pop it in the oven at 350 F. for 40 minutes and serve with fresh bananas, berries, peanut butter and plant based milk!

Literally NO DISHES or CLEANUP when you make this baked oatmeal. You mix it all right in the baking dish so that you don’t use unnecessary utensils or bowls. That’s my kind of baking! You can tell by looking at my Secretly Healthy Fudge Brownie recipe or Overnight Oat recipes. No dishes means more time to meal prep other healthy snacks like Almond Joy Protein Bites!

You can take a peek at my other baked oatmeal recipe to see a quick video of how exactly I make my healthy baked oats.

What gives this Chunky Monkey Baked Oatmeal Protein?

In this recipe, we use unflavored plant-based protein powder. This is a hidden gem that should not be hidden any longer! I would looooove for more people to discover the beauty of unflavored protein powder. I use this same trick in my Homemade Protein Pancake Mix recipe. Unflavored protein powder is so versatile and I love how it doesn’t overpower whatever you put it in.

You can use any protein powder in this baked oatmeal recipe though! I’ve had friends tell me they used flavored protein powder and the baked oats still turned out AMAZING. So feel free to experiment! A peanut butter or vanilla plant based protein powder would go over wonderfully, I’m sure!

Another source of protein we add to this baked oatmeal is peanut butter powder. I love this ingredient because it adds protein and flavor without adding a ton of extra fats. I use the same powdered peanut butter I did for my No-Bake Chocolate Peanut Butter Protein Balls (which are one of my favorite freezer snacks!).

How to store Baked Oatmeal

Store your baked oatmeal in the refrigerator for up to a week! It’s so easy to pull out of the fridge and heat up in the microwave. I love heating it for about 40 seconds until it’s warm but still a little cold so the chocolate chips are half melty. Yum!

Chunky Monkey Baked Oatmeal (GF+ Protein)

Chunky Monkey Baked Oatmeal

This protein packed Chunky Monkey Baked Oatmeal recipe is so easy and delicious! The perfect healthy meal-prep breakfast. Completely vegan and gluten-free. Definitely a healthy breakfast to go “bananas” over!

Prep Time 5 minutes
Cook Time 40 minutes
Total Time 45 minutes



1. Preheat the oven to 350 F.

2. In a 2 quart baking dish mash the banana with the back of a fork. Add all other ingredients into baking dish and stir until mixture is combined. (You can add a few extra chocolate chips to the top too)

3. Place in the oven to bake at 350 F. for 40 minutes. 

4. Enjoy hot out of the oven with bananas, an extra peanut butter drizzle and milk! 

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


  1. You can use any liquid of choice for this recipe. I use a combination of 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. I prefer using unflavored plant based protein powder. Vanilla, Peanut Butter, or Chocolate Peanut Butter are great flavor options for this recipe too! 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 powdered peanut butter? You can leave the powdered peanut butter out completely and reduce water amount to 1/4 Cup. OR use 2-4 Tbs regular all peanut butter. Use code "shh20" at Georgia Grinders for FREE SHIPPING on your nut butters!

    My kids and I love this recipe and make it at least once a week. This recipe is the PERFECT combination of oats, chocolate chips, bananas, and other nutritious ingredients making me start the day with a WIN. I love how easy it is too making my job, as a busy mama, easier.

    • Claire

      So glad you and your kiddos enjoy it! Easy and healthy is the best combo for busy mamas. Thank you so much for making it a part of your meals!

  • Bonnie

    This oatmeal is so good!!! Seriously so yummy and I love that it lasts for a week. I don’t have to worry about what’s for breakfast. And it was so easy to make. I will for sure be making it again and again.

    • Claire

      Yay!!! I agree, not having to think about breakfast is the BEST! Thank you so much for making it! So glad to hear you loved it 🙂

      • Marissa

        I have all of the ingredients except the powdered peanut butter. Is it necessary? Could I use regular peanut butter instead and if so, how much? Or…could I skip it if I use peanut butter protein powder? Not sure if leaving it out would change the texture or bake time? This sounds so yummy – can’t wait to try it! Thanks!!

        • Claire

          If you have peanut butter protein powder that would work great and you could skip the powdered pb. Or you can add in 2-4 Tbs regular peanut butter too if you want! That would be super yummy. If you do omit the powdered peanut butter reduce the water amount to 1/4 cup instead of 1/2 cup. Either way it shouldn’t affect the bake time. Please let me know how you like it and how it turns out 🙂 I’d love to see it!

          • Marissa

            Thank you for modifying the recipe for me! I used 4 Tbsp peanut butter instead of the powdered peanut butter and also used peanut butter flavored protein powder. Drizzled a little melted pb on top in the morning and added some fresh berries. Delicious!!

  • Alyssa

    I tried this recipe last week & it was just as good as the pictures! It was super easy to make, barely any of a clean up and the family loved it! I will definitely be making this again!

    I’ll make anything that requires so few dishes, especially when it’s SO YUMMY! My husband ate almost half the dish in one sitting. Love a good peanut butter/chocolate recipe, I will for sure be making this again.

    • Claire

      I couldn’t agree more about the no dishes, Emma! Love it. When the hubs approves it’s always a good day! Thank you so much for making it! So happy you loved it 🙂

  • MK

    So good!!! My boys loved this version! And mama loved that it’s in 1 dish, Healthy, and cooks while I take a shower/get ready!
    I don’t usually like cooked bananas, but they are the perfect sweetness and very subtle.

    • Claire

      This is the best! I love how your kiddos love it! And it makes a moms job that much easier while still being so healthy! Thank you so much for making it! 🙂

  • Rachel Phelps

    Hi there,
    Can this be portioned into portable snack bars (eaten cold) or would they fall apart?
    Thank you!

    • Claire

      Hi Rachel! This baked oatmeal is softer in texture and more moist but if you store it in the refrigerator and cut into squares they will hold their shape. And you can definitely eat them cold! Let me know what you think 🙂
