I know some people think of oatmeal as a sad and boring breakfast option. A bowl of mush if you will. But I completely disagree! And if you are here reading this post, I’m sure you do too. Oatmeal is a perfect vessel for all sorts of delicious things! I love to load up my bowls with fruit, nut butters, honey, chocolate chips, seeds … the list could literally go on and on. I also love to create endless new flavor combinations of baked oatmeal, as I’m sure you know if you follow me on instagram. My latest and might I say greatest flavor is Peanut Butter Banana Berry Baked Oatmeal. I know, quite a mouthful of a name but it’s indicative of the deliciousness of the recipe!!

In my opinion, oatmeal is one of the best breakfasts out there and I would and sometimes do eat it everyday! This baked oatmeal is full of complex carbohydrates and even more nutrients if you load up on wholesome toppings or add ins like I love to do. This helps to keep me perfectly full and satisfied for hours! If you find yourself hungry after eating your typical bowl of oatmeal, this recipe is for you.

Serving and storing Peanut Butter Banana Berry Baked Oatmeal

How to store…

This oatmeal needs to be refrigerated! I would not recommend leaving it sitting out for any long period of time. Once you remove from the oven, let cool completely, cut into squares, and then place in an airtight container to store in the fridge. This vegan oatmeal bake will last for about 1 week.

I recommend serving a slice of this baked oatmeal warm with some peanut butter, honey, and extra berries on top! Simply heat up a slice for about 45 seconds in the microwave, add your toppings, and enjoy. Makes for the perfect easy, delicious, and healthy morning meal!
