An easy one-bowl baked oatmeal recipe that’s easy and delicious!

I love eating oatmeal for but I hate the time and effort involved in making it every day.

Enter this baked oatmeal casserole – you can make a whole week’s worth of delicious breakfasts in one go!

I love thie recipe because:

• It uses rolled oats (aka Old Fashioned Oatmeal) which are healthier than quick oats
• I had everything I needed for making it already in my pantry
• It doesn’t use eggs and can be made vegan by using plant-based milk
• It’s delicious and not too sweet

On to the recipe for this one-bowl baked oatmeal with banana, chocolate chips, and peanut butter.

Baked Oatmeal Ingredients

Liek I said earlier, I was so happy that I could make this recipe with what I had on hand at my house. 

I saw some recipes that used eggs and others that didn’t. So considering the cost of eggs in the US currently, I decided to make this egg-free and it turned out amazing. 

The only ingredient not shown above is brown sugar, which is optional. I think adding 1/4 to 1/2 cup of brown sugar makes this super delicious, but if you are trying to cut back on sugar you can definitely leave it out. 

The bananas, chocolate chips, and peanut butter add plenty of sweetness as is. 

Here’s what you’ll need for this recipe: 

• 2 ripe bananas, mashed
• 3 cups rolled oats
• 1.5 cups milk ( I used extra creamy oat milk)
• 1/4 cup vegetable oil or butter
• 1 tsp baking powder
• 1/2 tsp salt
• 1/2 cup chocolate chips (I used milk chocolate but any kind will work)
• 4 tablespoons (1/4 cup) peanut butter

If you want this recipe to be gluten-free, just make sure you’re using gluten free oats.

And if you want to add more protein to your breakfast, just add some protein powder to the oats.

How To Make This Baked Oatmeal Recipe in One Bowl

I personally love any recipe I can make in one bowl, so this is yet another reason why I love this recipe. 

Here are the steps to bringing this together in one bowl (it’s not a very pretty recipe, so bear with me):

First, mash the two ripe bananas with a fork. The riper they are the sweeter this will end up being. 

Add the milk and vegetable oil next and mix well.

I have found that mixing in the peanut butter in at this point is the way to go, so add that too. 

Next add the oats on top and sprinkle the baking powder and salt over it. Mix everything together then add the chocolate chips and mix again. 

Baking the Oatmeal Casserole

Pout it into the greased 13 x 9 inch baking pan and put into the 375 degree Fahrenheit oven. Bake for about 30 minutes until all liquid has been absorbed. 

Wait until the oatmeal has cooled completely to cut. I cut mine into 12 sections but ended up having to take more than one piece per serving, so I suggest cutting this into 8 sections instead.

If you don’t have a 13 x 9 inch pan available, you can use a smaller pan, but you may need to add additional time for this to cook through. 

I save this on the pan in the fridge since the moisture content is pretty high and it might spoil if left out. When I want to eat it each morning I just reheat the oatmeal in the microwave for about 45 seconds and breakfast is ready!

Baked Oatmeal Variations

There are many different ways you can modify this recipe depending on your tastes and what you have on hand. 

If you only have quick oats on hand, you can substitute them 1:1 in this recipe. The result will be softer and less chewy which some people might prefer. 

You can leave out the peanut butter in this recipe or substitute more banana or applesauce for the oil. 

As I already mentioned you could add protein powder to this if you wanted extra protein as well. 

If chocolate chips at breakfast aren’t your thing, you could use blueberries or another fruit instead. 

Really the possibilities are endless for making delicious baked oatmeal with this recipe as a base. 

Baked Oatmeal Recipe Summary

I hope you enjoy this recipe! My husband needs to bring his cholesterol down so we love having healthy baked oats on hand for a quick breakfast.
