Nutritional benefits of this recipe
- Oats are a prebiotic fiber, which helps feed the beneficial bacteria in our gut. They also have vitamins and minerals such as zinc, magnesium, and B6. I like using sprouted oats because they are higher in protein, lower in starch, and easier to digest.
- Bananas are rich in potassium, magnesium, and vitamin B6.
- Eggs are a complete source of protein and are one of the richest sources of choline. They also have vitamin D3, folate, etc. Keep in mind, the egg whites are full of protein, while the egg yolks are where all the nutrients are.
- Maple Syrup – A natural sweetener that’s lower on the glycemic index than refined sugar and packed with minerals like manganese, zinc, and potassium, along with antioxidants.
- Collagen accounts for about 30% off your body’s protein. It provides structure, support, and strength to your skin, hair, nails, muscles, joints, connective tissues, bones, and more. It’s super easy to implement in your diet from adding it to coffee, smoothies, oatmeal, and more. I used Further Food collagen for this!
Ingredients for Peanut Butter Banana Baked Oatmeal
Rolled oats – I used sprouted rolled oats by One Degree Organics – they are lower in starch and easier to digest!
Bananas – use ripe, spotty bananas because they are sweeter.
Peanut butter – use an organic, natural creamy peanut butter with just peanuts and salt.
Eggs – this adds some more protein, vitamins, minerals, and healthy fats and make the oatmeal more rich and moist.
Baking powder
Salt
Vanilla extract
Optional for extra protein: Collagen peptides – I love Further Food.


How to make Peanut Butter Banana Baked Oatmeal
- In a large bowl, mix together the dry ingredients. Pour in the milk and stir together.
- Add the remaining wet ingredients and mix throughly to combine everything.
- Oil an 8×8 baking dish – I used a light stainless steel pan for reference.
- Pour the oatmeal mixture into the baking dish.
- Drizzle the additional 3 Tbsp of peanut butter on top, then take a knife to subtly swirl it through the oatmeal.
- Let the mixture rest while you preheat the oven to 350°F. This gives some time for the oats to soften a little, which is important for sprouted oats specifically.
- Bake for 40-50 minutes until a toothpick comes out clean. Mine was perfect at 45 minutes in a stainless steel pan. This time may vary based on your oven as well as the type of dish you use. If you are using a dark aluminum pan then maybe check it at 35-38 minutes because they cook so much quicker!
- Remove baked oatmeal from the oven and let sit for 10 minutes before slicing. Enjoy!

- Sub almond butter in place of the peanut butter – or follow my Almond Butter Banana Baked Oatmeal recipe that is very similar.
- Add ground cinnamon for a touch of warmth.
- Incorporate cacao powder for a chocolate flavor.
- Add chocolate chips for a little sweetness.
