Mornings at our house or typically busy. I’m the first one up, and I quickly head out the door before my guys wake up. I head to the gym for a 6:15 workout at my local Orange Theory studio.

Here are the simple steps to making this healthy baked oatmeal recipe:

Step 1: Make sure you have the ingredients

The ingredients for this banana baked oatmeal are pretty simple – you likely already have them in your pantry and fridge. Here’s a quick-reference list of the ingredients you’ll need:

• 3 ripe bananas (2 mashed with the oatmeal and one sliced for the topping)
• 2 eggs
• Milk (diary or plant-based)
• Vanilla
• Honey
• Salt
• Peanut Butter or Nut Butter – do your best to use a good-quality nut butter. Ideally one without vegetable oils, soybean oils or added sugar.
• Old-Fashioned Rolled Oats
• Chocolate Chips – good quality. I like the Enjoy Life brand which are pictured in these photos. These are made without toxic oils and refined sugar. If you’re looking for some sugar-free options, I also love Lakanto Sugar-Free Chocolate Chips and Lily’s No Sugar Added Dark Chocolate Baking Chips.

Step 2: Mash bananas and whisk in the other wet ingredients

You’ll start by mashing two of the bananas – set the remaining banana aside. You’ll slice this and use it for topping the baked oatmeal. 

To the mashed banana you’ll add the eggs, honey, peanut butter, vanilla and milk. Whisk together well until all is well incorporated.

Step 3: Add in the oatmeal and salt

To the wet ingredients, you’ll then stir in the oatmeal and salt.

Using a rubber scraper, pour into a prepared 9 x 9 baking dish that you’ve lightly sprayed with non-stick baking spray. I use and prefer Spectrum Non-Stick Coconut Oil Spray. Spread the oatmeal mixture evenly into the prepared pan or dish.

Step 4: Top the oatmeal with the bananas and chocolate chips

Top the oatmeal with the remaining sliced banana, and the chocolate chips. I used these Enjoy Life Mega-Chunks in this peanut butter banana baked oatmeal.

The chocolate chips are certainly optional. If you would prefer to save yourself a few calories, leave these out and top with just the banana slices. I love these baked oatmeal bars WITH the chocolate chips, it adds a great flavor and tastes like a treat!

Step 5: Bake the Banana Baked Oatmeal 

Bake the oatmeal for 35-40 minutes. It will smell glorious and like you’re baking a fresh loaf of banana bread. If you love banana bread, be sure to check out some of my banana bread recipes: Chocolate Chip Peanut Butter Banana Bread , Purple Ribbon Banana Bread, Double Chocolate Banana Bread.

Once the baked oatmeal comes out of the oven, let cool to room temperature before slicing.

I love drizzling with some additional nut butter and heating in the microwave for a few seconds. This healthy baked oatmeal recipe is hearty, filling and the perfect way to start your day. I absolutely love this Wild Friends Cashew Super Butter.

FAQ’s for Peanut Butter Banana Baked Oatmeal:

Can baked oatmeal be made the night before?

• Yes. Simply mix the banana baked oatmeal the night before and top with the sliced bananas and chocolate chips. Cover with plastic wrap and refrigerate. In the morning, take out of the refrigerator, remove plastic wrap, and preheat oven. Bake as directed.

• Yes. This is a great healthy carb and healthy fat combination. It’s good as a snack and great in this healthy baked oatmeal recipe.

Can you substitute quick oats for rolled oats in baking?

• Yes. It is a 1:1 ratio swap. I prefer rolled oats as they are less-processed than quick oats. Rolled oats tend to reheat better – quick oats tend to get a little mushy.
