ingredients to make banana bread baked oatmeal

Bananas – Adding a delicious natural sweetness, go banana bread style and make sure they’re super ripe!
Eggs – Add protein, fat-soluble vitamins, and help bind the oatmeal bake together.
Brown Sugar – I love brown sugar as a flavorful, affordable sweetener (and metabolically speaking, sugar is sugar when it’s all broken down in the body). If you’re looking for a sugar-free option, I often make this with this Truvia’s Sweet Complete Brown Calorie-Free Sweetener made with Stevia.
Milk – You can use any kind of milk you prefer to drink. If you want a higher protein option, I’d choose cow’s milk, soy, or a fortified alternative.
Old-Fashioned Oats – Old-fashioned work best here, and I don’t recommend quick oats or steel cut oats, as the texture and consistency don’t turn out the same. If you’re gluten-free, you can use certified gluten-free oats.
Ground Flax Seed – Flax seed adds some heart healthy omega-3 fatty acids and more fiber. They also contribute to binding and creating the best consistency. Make sure you use ground, though, as whole flax seeds aren’t as easily digested!
Baking Powder – Needed for leavening
Flavorings – Vanilla bean paste or extract, cinnamon, nutmeg and a little salt are all used to enhance the flavor. You can skip the salt if it’s not your thing! I use Diamond Crystal Kosher Salt, which contains 53% less sodium than traditional table salt, due to the unique shape of Diamond’s crystal salt.

stirring all ingredients for banana bread baked oatmeal

Once bananas are mashed, whisk together all the wet ingredients (I used a Danish dough hook in the pictures, but I’ve also mashed and whisked it together with just a fork before, too!). Then add remaining dry ingredients and stir until combined.

Tips and Variations

Add your favorite mix-ins! It’s honestly my favorite on its own, but if you’re someone that likes a little crunch or chew, try adding some toasted nuts, seeds, dried cranberries, or (my kid’s favorite) some mini chocolate chips.
Add toppings! I like to top mine with vanilla Greek yogurt and extra banana slices, but you could also do a drizzle of peanut butter, or whatever else sounds good!
Make it sugar-free by using Truvia’s Sweet Complete Brown Calorie-Free Sweetener made with Stevia.

Storage, Freezing, & Reheating

Banana bread baked oats are absolutely perfect for meal prep! To store, simply place in an airtight container in the fridge for up to 4-5 days. You can also freeze in airtight containers/ packaging for up to 3 months.

Truthfully, you can eat this baked oatmeal straight from the fridge, and it still tastes amazing. But you could also reheat in the microwave for 30-45 seconds, until warmed through.
