BAKED OATMEAL

I love eating oatmeal for breakfast, especially when it’s baked because it’s so easy and makes the best leftovers. This Healthy Banana Baked Oatmeal is baked into a fluffy, sweetened, and bread-pudding like breakfast treat. It’s perfect for storing as leftovers or meal prepping for the week. 

This soft and moist Banana Baked Oatmeal recipe is one of my favorites because it tastes like banana bread and made with natural sweeteners so you can feel good about eating this treat. Topped with walnuts for crunch, more sliced bananas, and a drizzle of warm maple syrup.

You can enjoy baked oatmeal warm, cold, or as a dessert! Some of my other favorite baked oatmeal recipes are Blueberry Baked Oatmeal, Gingerbread Baked Oatmeal, and Pumpkin Spice Baked Oatmeal.

INGREDIENTS

Old-fashioned oatmeal: you could also use plain instant oats. Steel-cut oats won’t work for this recipe because they need a lot more moisture so the recipe will have to be altered.

Baking powder: will make the oats rise a bit.

Salt: enhances the sweetness.

Ground cinnamon: adds the perfect amount of spice. 

Bananas: the riper, the better. I love using bananas that have lots of spots on them.

Maple syrup: I always prefer pure maple syrup for a healthier option. 

Milk: any type of milk will work perfectly. Almond milk can also be used. 

Eggs: makes this oatmeal bakes fluffy and used to bind the ingredients together. 

Coconut oil: make sure to melt the oil before so it incorporates into the mixture. Butter or vegetable oil can also be used. 

Honey: make sure to melt the honey. You can also use agave syrup instead. 

Walnuts: almonds, hazelnuts, peanuts, or cashews can be used. This is optional to add some crunch.

TIPS

  • Make into Oatmeal Cups by baking the oatmeal in muffin pans instead of a baking dish. Make sure to grease the muffin pans generously or line them with paper or silicone liners. 
  • You can easily make this into a dessert by serving it warm with a scoop of vanilla ice cream on top. Yummm!
  • Serve this oatmeal by cutting it into squares, rectangles, or by scooping it into a bowl. 
  • If you want to make this oatmeal more like traditional oatmeal, simply pour warmed milk or almond milk over it. 
  • If you want to add even more protein, add 1/2 cup of plain flavored or vanilla protein powder to step two of the recipe instructions.

RECIPE VARIATIONS

This oatmeal is so versatile and just about any of your favorite flavors can be added.  Some of my favorite variations are below:

Peanut Butter Baked Oatmeal: add a few tablespoons of peanut butter or any nut butter to the oatmeal mixture. You can also swirl the peanut butter on top. 

Berry Baked Oatmeal: add fresh or frozen berries to the oatmeal mixture and on top. 

Chocolate Chip Baked Oatmeal: chocolate and oats pair so well together. Add a handful of either dark or milk chocolate chips.

Birthday Baked Oatmeal: add sprinkles to the top of the oats if you are wanting to make this for a fun occasion or birthday.

Other ingredients that would make a delicious addition to the original recipe are shredded coconut, raisins, or chopped nuts such as almonds, peanuts, walnuts, pecans, or hazelnuts.

LEFTOVERS & STORAGE

Store leftovers in an airtight container for up to 5 days. When ready to reheat, place in the microwave and heat for 15-45 seconds depending on your microwave. 

To freeze: make sure the oatmeal is completely cool, then cut into 9 squares and wrap each into plastic wrap or foil, then place into a large ziplock bag. When you’re ready to eat it, thaw overnight then microwave for 30 seconds- 1 minute. 

You can also defrost the oatmeal in the microwave for a few minutes until thawed and warmed.

    This is so awesome and really does taste more like a desert. Such an easy recipe and nice to have something small on hand to grab a quick snack or take on the go.

  5. I left out the maple syrup to cut down on the sugar and it was still amazing. Can’t wait to make other versions!

  6. 5 stars
    This was delicious and super fast to whip up. I used super ripe bananas, sugar free maple syrup, no honey needed and added a cut up peach and a handful of blueberries to the mix. Not to sweet since I’m watching my sugar and calories. Excellent for breakfast or snack!
