Baked Oatmeal Bars with Banana’s and Nutella
Baked oatmeal bars with banana and Nutella are easy to make; it just takes ingredients you probably already have in one bowl and 25 minutes in the oven. After that, you can enjoy oatmeal bars all week. How is that for easy meal planning?

If you’re new to baked oatmeal, it is another way to cook this great grain. Like overnight oats, the flavors are entirely customizable to your preference. I used two of my favorites for this recipe: bananas and Nutella. However, if you’re not a fan of Nutella, no problem; swap it out for peanut butter. If you are not in the mood for bananas, no problem. Just swamp 1/2 cup of applesauce for each banana. If you like nuts, go ahead and add them. The combinations are endless.
I love that this recipe is perfect for meal prepping. I can make it on a Sunday and have an oatmeal breakfast all week.
Ingredients
- Nutella (1/2 cup)
- Bananas (2 mashed/2 for toppings)
- Whole or Quick Oats (2.5 cups)
- Brown Sugar (1/4 cup)
- Milk (1/2 cup)
- Vanilla (1 tsp)
- Egg (1)
- Baking Powder (1 tsp)
- Salt (1 tsp)
- Cinnamon (1/2 tsp)
Instructions
To mix the ingredients, start with the banana. In the pictures below, I used my mixer; however, a mixer is unnecessary for this recipe. Here are the two different ways you can mash bananas.
- To mash the bananas in the mixer, turn the mixer onto a low to medium speed with the beater attachment for 1 – 2 minutes.
- To mash with your hands, ensure the bananas are ripe and squish between your fingers until you reach a smooth consistency.
Once the bananas are mashed, combine them with the rest of the ingredients and pour them into a parchment-lined baking dish. The pour will be thick (see below). Once poured, bake at 350 degrees for 25 – 28 minutes.


Once baked, remove the oatmeal from the oven and allow it to cool for 30 minutes. Then place in the refrigerator for one to two hours. This will allow the oatmeal to become firm and easier to cut.
Because I prefer to bake oatmeal the day before, I leave this dish in the refrigerator overnight. Before eating, top as desired with banana, strawberries, apples, peaches, warmed Nutella, etc. (The strawberries I used below are dried.) Get creative here and have fun coming up with different toppings!
