Peanut Butter Banana Baked Oatmeal: Substitutions
This recipe is very versatile, read below for possible substitutions. Note: make sure the ingredients are room temperature.
- Quick Cooking Oats: The texture is the best with quick cooking oats. If you only have old-fashioned (or rolled) oats, pulse them 2-3 times in a blender or food processor until they are the same texture as quick-cooking oats and then use them in this recipe.
- Creamy Peanut Butter: Any nut or seed butter works well in this recipe – examples include sunflower seed butter or almond butter. You can also use crunchy peanut butter .
- Maple Syrup: honey is a great substitute.
- Egg: A chia or flax egg (1 Tablespoons ground chia seeds or flaxseed mixed with 2 ½ Tablespoons hot water) can be used in place of a regular egg.
- Milk: I use whole milk, you can use almond milk, coconut milk, 2% milk, even half and half works well.

This recipe was delicious. I usually have to tweak every recipe I find online, but this one was perfect from the get go. Even my picky husband loved it, and he hates oatmeal.
I made this last week for my 3 boys for breakfast. I used 2% cow’s milk, and stirred in some hemp seeds for add protein. I warmed it up in the morning and poured a small amount of cream on top, and sprinkled it with cinnamon. They loved it. I have more in the oven tonight using coconut milk instead of cow’s milk. Very easy recipe, and very easy breakfast for 3 boys on a school day! Thanks!
I’ve tried a lot of recipes for baked oatmeal and it seems like they often come out gummy or flavorless, so I keep coming back to this one! It’s delicious and the texture is fluffy and perfect. I love that I can keep it in the fridge and just pop a slice in the microwave for a quick and healthy breakfast. I do find that if I use very ripe bananas they make the oatmeal plenty sweet for my taste so I omit the maple syrup in order to cut the sugar content.
Simply out of this world.!!! Wow, what a treat. I only had rolled oats and the bars turned out super- yummy. I used chia seeds, and it needed more hot water. Final presentation, I sprinkled some raisins, chopped pecans and raw sunflower seeds. Ridiculously simple recipe with amazing results. Thank you!
This is a great quick breakfast since it can keep in the fridge. I like to serve it in a bowl and add milk. Thanks for a great recipe!
I love the idea of adding milk! My oldest likes her oatmeal on the moist-side!
This is one of my favorite recipes ever. I also gifted some to my sister and sister-in-law after they had babies, as these are a powerhouse for nursing moms. My son loves these too!
What a great idea to bring it to a new mom!
Theses are delicious! I made them for my daughter who is a 17yr old high school athlete, she loved them ❤️
I’m so glad your daughter loved this recipe Lucy!
My 2nd time making this recipe. It’s so great and so easily modified to anyone’s preferences…thank you! I wanted to “up” the protein so i added 2 scoops of protein powder. I also added 1/4 cup of walnuts and replaced syrup with liquid stevia.
I pack them individually, refrigerate and warm either in the microwave or the broiler. My favorite meal prep breakfast to date!
i love the idea of baking it the night before but wonder if it will taste as good as fresh baked. Any tips on how to reheat it in the morning without using a microwave? Can I put it back in the oven in the morning or will it dry it out too much?
Just made this – Delicious! Was wondering for next time if this recipe could be assembled and refrigerated overnight and then baked in the morning?
I’m so glad you enjoyed it Shannon! I am unsure, but I don’t see why that wouldn’t work! I usually bake it the night before and then reheat it in the AM!
