When I need a quick breakfast that actually keeps me full until lunch, I make this banana baked oatmeal. It takes just five ingredients and barely any effort.
What makes this better than regular oatmeal is the texture. The edges get crispy while the middle stays soft and chewy. Plus, the banana and chocolate combo tastes like dessert even though it’s pretty healthy. I usually make a pan on Sunday and eat it throughout the week.

Step-by-Step Instructions
Making this baked oatmeal is straightforward and takes just minutes to prepare before baking.
Preparing Your Banana Oatmeal Ingredients
Before you start mixing, make sure your ingredients are ready to go. This makes the process much smoother.

Step 1: Preheat your oven to 350°F (180°C) and line an 8-inch square baking pan with parchment paper.
Step 2: Mash your ripe bananas with a fork until mostly smooth. A few small lumps are fine and will add nice banana flavor pockets to your oatmeal.
Note: If your almond butter is stored in the refrigerator, let it sit at room temperature for 10-15 minutes before using. This makes it much easier to mix with the other ingredients.
Mixing The Batter
The mixing process is very simple, but there are a few things to know for the best results.

Step 3: Add 4 cups of rolled oats to your mixing bowl. I like using gluten-free sprouted oats because they taste nuttier and are more nutritious. I left the link in the description below.
Step 4: Add one cup of almond butter to the oats. Peanut butter would work just as well if that is what you have in your pantry.
Step 5: Add one and a half cups of ripe mashed bananas, which is about three to four bananas. Make sure to use really ripe ones with brown spots for the best sweetness.
Step 6: Add 1/4 cup of maple syrup or honey. Both work great for sweetness.
Step 7: Add half a cup of chocolate chips. I like using semi-sweet dark chocolate because they are not too sweet and they have a deeper chocolate flavor.
Step 8: Mix everything together until well combined. The mixture will be thick and hold together well.
Baking Your Healthy Banana Oatmeal Squares

The baking process is where the magic happens, turning your mixture into a delicious breakfast treat.
Step 9: Scoop all the oat mixture into the pan. The mixture is thick and dense because of the bananas and almond butter, so you need to press it down really hard with a spatula. It really helps if you cut them into bars later, so they would not fall apart when you pick them up or pack them in a lunchbox.
Step 10: Sprinkle a bit more chocolate chips on the top and put it in a preheated oven for 15 to 20 minutes at three hundred fifty degrees Fahrenheit or one hundred eighty degrees Celsius. I always wait for the edges to get golden brown and crispy, but do not worry, the center still stays soft and deliciously chewy.

How To Serve Freshly Baked Banana Oatmeal

These baked oats are best straight out of the oven, with crispy edges and chewy centers, but they are also good to pack for lunch boxes or breakfast on the go. They stay fresh for about four days.
I love eating a square while it is still warm, sometimes with a small dollop of yogurt on top. The contrast between the warm oatmeal and cold yogurt is really nice. My kids prefer theirs plain, especially when the chocolate chips are still melty.

Top Tip: For an extra special breakfast, warm up a square and top it with a spoonful of almond butter and some sliced fresh banana.
Storage Instructions
This baked oatmeal stores beautifully, making it perfect for meal prep.
- Allow the baked oatmeal to cool completely before cutting into 9 equal squares.
- Store in an airtight container in the refrigerator for up to 4 days.
- To reheat, microwave a square for about 20-30 seconds or enjoy it cold straight from the fridge.
Note: You can also freeze these squares for up to 3 months. Just wrap each piece individually in plastic wrap and place it in a freezer bag. Thaw overnight in the refrigerator before eating.
Easy Variations and Substitutions
This recipe is very flexible and can be adapted based on what you have on hand.
Different Nut Butters For Baked Oatmeal

Sweetener Options For Healthier Oatmeal
The recipe works with various sweeteners:

You can customize this recipe by adding:

Top Tip: If you want to reduce the sugar content, you can skip the maple syrup entirely if your bananas are very ripe and sweet, or replace the chocolate chips with chopped nuts.
