This baked oatmeal recipe is one of the best ways to enjoy oats! And it’s one of my favorite breakfast recipes to make for a meal prep heavy week.

Simple to make, you can have it ready for a healthy breakfast in under 30 minutes.

Mix the ingredients together, place in oven, go get showered for the day, and breakfast will be hot and ready for you.

My love for baked oatmeal goes back to 2008, and I’ve been making different variations for years. (See them linked at the bottom of this post.)

Since stove-top oatmeal in a bowl is hard for toddlers to eat, this is one of the best ways for littles to enjoy oatmeal. It’s a fabulous toddler finger food cut into bite-size pieces. The texture of baked oats is similar to bread pudding – firm enough to eat with a fork or pick up yet not as solid as a cake.

What kind of oats should I use?

I recommend rolled oats for this recipe, but you can use quick oats in a pinch. The texture will be a bit less hearty, and you may decrease the cooking time a bit for the increase in surface area / quick absorption that quick oats have.

Baked Oatmeal Nutrition

When cut into six servings, each base recipe serving is about 225 calories, 10 grams of protein, 5 grams of fiber, 5 grams of sugar, and 5 grams of fat.

The 5 grams of sugar is coming from natural sweeteners (banana and milk) rather than added sugar.

You’re also getting 56% of daily calcium and 12% of daily iron.

You can also make it gluten free by using certified gluten free oats. Add in chia seeds, nuts of your choice, or other fruits for added nutrition.

Note this is with cow’s milk, so almond milk will bring the protein down a little. Subbing in flax eggs will also change the nutrition a bit.

Get The Sweetness From Bananas

Make sure you use very ripe bananas that have some brown spots, like on their way to banana bread status, so you’ll get plenty of natural sweetness.

You can add a few tablespoons of brown sugar or pure maple syrup to the dry ingredients if you would prefer more of a sweet taste.

Baked Oatmeal Topping Ideas

I do like to add a little brown sugar or maple syrup broiled on top at the end so it gets nice and bubbly with a caramelized crust!

You can also mix in chopped nuts (or sprinkle them on top), fresh, frozen or dried fruit, chocolate chips, pumpkin, and more!

Or add this peanut butter cream frosting made with yogurt, PB2, and milk for a nice extra layer of flavor!

How To Make This Baked Oatmeal Recipe

Prepare wet and dry ingredients

Mash ripe banana until it’s nice and soft. Beat your egg. Mix in milk and vanilla extract. You can use cow’s milk or almond milk.

Mix dry ingredients together in a large bowl (rolled oats, baking powder, cinnamon, salt.)

Pour wet ingredients into the dry ones

Mix well!

Pour into greased pie dish

You can grease your pie dish with melted butter, coconut oil, or cooking spray. Top with more banana slices

Bake

Pop into a 375 degree oven for about 26 minutes, until golden brown on edges

Optional: Brown sugar broil

After 26 minutes, increase heat to broil, sprinkle oatmeal with 1 heaping tbsp brown sugar and broil for 3-4 minutes.

Serve warm or store in the fridge and reheat

Different ways to adapt the recipe:

Bake in 8″ square baking pan lined with parchment for easy lift out and thinner slices
Use a smaller baking dish for more “loaf” sized slices (see the Pumpkin recipe below)
Make in muffin tin for easy cups (great to freeze!)
Double the recipe and use a bigger pan to feed a crowd!

How To Serve Baked Oatmeal

Serve it immediately warm from the oven! You can cut into pie slices (which feels fancier to me) or in squares (which might be easier to get perfectly out of the pan, especially if you use a square baking dish.)

To store, simply allow to cook and place in glass food storage containers in the fridge. Reheat in the microwave for 30-60 seconds, until warm throughout.

You can also turned the baked oatmeal into bowl oatmeal by adding some milk before you reheat it and then stirring until the creamy milk creates a more porridge-like texture. Add mixins and toppings like you would oatmeal made in the microwave or on the stovetop.

Topping Idea: Peanut Butter Frosting

This “frosting” is my new jam. It’s a mix of plain Greek yogurt, PB2 peanut butter powder, and milk that I mixed until I got a thick-ish consistency and then piped onto the pie.

The topping is not sweet so add some sugar if you want more of a dessert frosting! I would eat it with a spoon too.

Baked Oatmeal Recipe with Peanut Butter "Frosting"

This classic baked oatmeal recipe with bananas has been a favorite for years in our house. It's super simple to mix together and pop in the oven while you get ready. An optional brown sugar broil adds a little caramelization and a peanut butter cream "frosting" has no sugar.

For The Peanut Butter Frosting

Mix yogurt, powdered peanut butter and milk until you have desired consistency. You might have to add a little more or less than the recipe calls for - just keep going until you have something you can pipe. You can also add some cane sugar if you'd like!
Once the frosting consistency is to your liking, scoop into a piping bag or ziplock and squeeze onto oatmeal pie.
