Does anybody else feel like every morning is a chaotic race against the clock? I know it is for my family – by the time I get my morning workout in, shower, get the kids ready and attempt to look somewhat put-together myself, time for breakfast seems to be minimal. 

No matter how busy the morning is, I’m not one to skip breakfast – I truly believe it is the most important (and most delicious!) meal of the day. A couple of my favorites are Cottage Cheese Pancakes, fruit and yogurt smoothiesSausage and Sweet Potato Hash and this baked oatmeal recipe!!

Why I Love This Recipe

  • It’s great for a healthy breakfast or a healthy treat when your sweet tooth is calling (tastes like a peanut butter cup)!
  • It’s made with simple ingredients that most people have on hand.
  • The whole family loves it and it’s a great way to get added fiber and protein in!

Ingredients You’ll Need

  • Banana – A super ripe banana is my preference as it’s super sweet and easy to mash up!
  • Peanut Butter – You’ll use peanut butter in the baked oats and on top!  
  • Eggs 
  • Maple Syrup – You can really use whatever sweetener you’d like (honey or agave works great too!)
  • Vanilla Extract
  • Milk – You can use whatever milk you’d like!  Dairy milk, almond milk, cashew milk, etc.
  • Baking Powder 
  • Oats – I like to use a combination of old fashioned oats (rolled oats) and quick oats.
  • Chocolate Chips – I like to use mini chocolate chips for better distribution, but semi-sweet or dark chocolate chips will work great too.
  • Flax Seed, Protein Powder and Cocoa Powder are all great optional add-ins! Add 2-4 tablespoons of any of them to the batter before baking.

How to Make Baked Oatmeal

Grease the baking dish with cooking spray.

In a large mixing bowl, mash the banana and whisk in the peanut butter, eggs, maple syrup, vanilla and milk.

​Add the baking powder, oats and chocolate chips to the wet ingredients and stir until combined.

Pour into the prepared baking dish and sprinkle with the remaining chocolate chips.

Bake until the center of the oats have just a little wiggle in the center.

Turn them into Baked Oatmeal Muffins

I often pour the oats into a 12-cup muffin tin instead of a square pan for easy portion control!  Fill 12 greased muffin cups completely full, top with chocolate chips and bake for 12-15 minutes.

You can even blend the batter before baking for a smoother muffin!

Frequently Asked Questions

What should I serve with baked oatmeal?

I like to serve it with fresh fruit and Greek yogurt for added protein to start the day!

Can I use a substitute for the peanut butter?

Yes!  Simply use the same amount of almond butter or cashew butter as the recipe calls for.  This is a great option if someone is allergic to peanuts.

Can I make this baked oatmeal dairy free?

Yes!  Simply use a milk alternative and use dairy-free chocolate chips.

Is baked oatmeal gluten free?

Oats are naturally gluten free.  However, many oats are processed in facilities that also process wheat products.  Therefore, if you have an allergy to gluten, be sure to use a package of oatmeal that specifies that it is in fact gluten free.

How should I store leftover baked oatmeal?

Let the oatmeal cool completely then cover with plastic wrap or place in an airtight container.  Store in the fridge for up to 5 days.

What’s the best way to reheat baked oats?

​I typically reheat them in the microwave, but you could also pop them into the air fryer for a few minutes for yummy crispy edges!

Recipe Notes & Substitutions
Banana: If you don’t have any bananas in the house, use applesauce instead.
Milk: Any kind of milk should work for this (skim, 2%, almond, coconut, etc)
Peanut Butter: I’ve also tried this recipe with powdered peanut butter (PB2) and really liked it – it still has great peanut butter flavor but with fewer calories and fat. If you decide to go this route, simply increase the milk to 1 3/4 c.
Chocolate Chips: You can also use regular chocolate chips (instead of mini). I like mini because you get a little bit with every bite!
Maple Syrup: If you don’t have any maple syrup, you can use honey or agave nectar instead.
