5 reasons to love this simple baked oatmeal
I absolutely love this 3 ingredient oatmeal recipe, and I’m pretty sure you will love it too! Here are 5 reasons why!
- This recipe is incredibly simple. With just 3 ingredients, this oatmeal may be the easiest breakfast bake ever!
- Baked oats are healthy. Oats are a whole grain that is rich in dietary fiber, plant based protein, minerals and vitamins. What is more, this recipe is eggless, vegan, sugar-free and gluten-free.
- This baked oatmeal is diet-friendly. Eggless, dairy-free, vegan, gluten-free (if you use GF oats), sugar-free and easily high protein.
- It’s customizable to your preferences. While the base of the recipe has just three ingredients, you can get creative with add-ins to match your taste preferences.
- Baked oatmeal is incredibly convenient. Make it ahead and you’ll whip up breakfasts, desserts and snacks for the whole week. It’s great for meal prepping too!
The ingredients
This is a pretty easy baked oatmeal recipe. It only calls for three basic ingredients that you probably already have at home. No egg, no dairy, no oil and no sugar at all!
- Ripe banana: For this recipe you’ll need two large ripe bananas. Ripe bananas are perfect because they come with more sweetness and mash very well. As a replacement you can also use about a cup of unsweetened applesauce.
- Rolled oats: This breakfast bake recipe requires rolled oats (also known as “old-fashioned” oats). Differently from quick oats that tend to get soggy, rolled oats will give your breakfast a better taste and texture. If you have dietary requirements or allergies, choose certified gluten-free oats.
- Nut butter: Use a creamy nut butter of your choice, preferably natural and without added sugar or oil. My recommendations are smooth peanut butter, almond butter and cashew butter. For a nut-free baked oatmeal, replace with sunflower seed butter or tahini.
Additional ingredients
As this recipe is very simple, it leaves plenty of room for customization. Make it high protein, chocolatey or extra fruity, the options are endless. And if you still need ideas, here are a couple of extra ingredients you can add to this 3 ingredient baked oatmeal recipe. Pick and choose your favorite or mix and match. I love mine with chocolate chips and an extra scoop of protein!
- Chocolate chips: Dark chocolate chips, semisweet chocolate chips, milk chocolate chips or sugar-free chocolate chips.
- Nuts: Crushed walnuts, pecans, almonds, cashews, hazelnuts.
- Seeds: Pumpkin seeds, sunflower seeds, flaxseeds, poppy seeds.
- Dried fruits: Raisins, cranberries, dried berries, dried apple.
- Fresh fruit: Blueberries, raspberries, a mix of fresh berries, apple chunks, diced pear, pieces of mango.
- Flavors and spices: Ground cinnamon, vanilla extract, nutmeg, cocoa powder.
- Protein powder: Replace 30 grams (1/3 cup) of the oats with your favorite protein powder. Keep on reading for more details.
High protein baked oatmeal
Are you following a high protein diet? I got you. I am always looking for ways to sneak in some extra protein into my meals. Especially when it comes to breakfast! That’s why I’ve included an option to make easy baked oatmeal with protein powder. As simple as that, all you have to do is replacing 30 grams (or 1/3 cup) of the oats with protein powder and you are set to bake. I always do so!
Just keep in mind that different types of protein powder behave differently when baking. So, this recipe may require some adaptations. As a rule of thumb:
- Vegan protein powders and casein are more absorbent. This means the oat dough may need an additional pour of milk, in case it is too thick.
- Whey protein powder mixes very well. Therefore, you may need to fix the dough with more oats.
In terms of flavor, you have the freedom to pick and choose the one you like the most. But still, my suggestion is to opt for simple options, such as chocolate or vanilla (my favorite).

How to make easy baked oatmeal with 3 ingredients

Prepare for baking. Before starting, preheat the oven to 180°C (350°F) and fold a 15 cm x 15 cm (7 inch x 7 inch) brownie pan with parchment paper. This way you’ll be set to bake once the oatmeal dough is ready.
Make the oat dough. In a large mixing bowl, mash the ripe bananas completely. Once mashed, add in the nut butter and stir until you get a smooth mixture. Add rolled oats to the banana mixture and give it a good stir until combined. Optionally, you can mix in additional maple syrup, a pinch of salt and chocolate chips.
Bake oatmeal. Transfer the dough to the prepared parchment paper covered baking pan and top with more chocolate chips, if you desire. Bake in hot oven for 15 to 20 minutes and let cool at room temperature before slicing.

How to store baked oatmeal
After baking, let the baked oatmeal cool over a baking rack or plate. Once cool, slice into bars and seal in an airtight food container. Store at room temperature for up to 3 days. Make sure you wrap it well, or it will get dry if exposed to air and humidity.
For a longer storage, pre-slice and freeze in an airtight food container or in a zipper bag for up to 3 months. Before serving, take out from the freezer and pop in hot oven to reheat for a couple of minutes. As a quicker option you can also microwave it for a few seconds.
FAQ – Frequently asked questions
Yes, it definitely is. You’ll only need oats, banana and a nut butter of your choice.
If you don’t like bananas, replace with about a cup of unsweetened applesauce or pear sauce.
If you allergies or dietary requirements, be sure to make this recipe with certified gluten-free oats.
It depends on your preferences. For me, ripe bananas already give plenty of taste. But if have the sweet tooth I recommend adding a couple tablespoons of maple syrup or honey.
Indeed, it’s so simple! All you have to do is replacing 30 grams (1/3 cup) of the oats with the same quantity of protein powder. Based on your protein powder choice you may need to fix the dough with additional oats (if too wet) or with a couple tablespoons of milk (if too dry).
I do not recommend cooking your oatmeal in the microwave, the result won’t be the same. This recipe should be made in the oven.
