Peanut Butter Banana Baked Oatmeal

Peanut Butter Baked Oatmeal is lightly sweetened with bananas and honey. Your morning oatmeal meets up with banana bread in this fun twist on a classic breakfast.

Served warm, topped with sliced bananas and a drizzle of peanut butter, it’s a favorite with kids and adults alike.

Oatmeal has been a favorite breakfast in our house for years. Apple Cinnamon Oatmeal, Pumpkin Pie Oatmeal, Slow Cooker Oatmeal with Strawberries and Bananas, Peaches and Cream Oatmeal, and Berry Baked Oatmeal are just a few of the oatmeals that make repeat appearances in our home.

Whether the oatmeal is made on the stove, in the oven, or in the crockpot, there really isn’t a way in which my family doesn’t enjoy oatmeal.

Thankfully, my kids can stir together a baked oatmeal recipe and get it in the oven all by themselves now. So, naturally, they ask if they can make it at least once a week.

Peanut Butter Baked Oatmeal

This recipe for baked oatmeal is loaded with peanut butter and bananas and lightly sweetened with honey. The Peanut Butter and Jelly Oatmeal was such a hit with my PB&J-loving kids, it was no surprise that they loved the peanut butter baked oatmeal too!

I had the idea for it a while back and I’d scribbled out the recipe already, so I handed my notes to my 10 year old and went to relax with my morning coffee while he made breakfast for all of us.

(Side note: I thought I’d really miss having little ones in the house, but having older kids has turned out to be pretty awesome!)

My youngest declared this one of his best breakfasts ever and begged for the leftovers the next day. Another great thing about baked oatmeal is that most of the time, we get two meals out of it. It freezes great and keeps nicely in the refrigerator for a few days as well.

Peanut Butter Baked Oatmeal

1. Preheat the oven to 350°F. Grease an 8×10 or 9″ square pan with butter. In a large glass bowl, heat the peanut butter and the honey in the microwave for about 30 seconds. Stir and heat an additional 15-20 seconds, as needed, to liquify the peanut butter.
2. Stir in the mashed bananas, sour cream, and eggs. Add all remaining ingredients and stir again. Pour into the greased pan. Bake for 35 minutes, until a knife comes out mostly clean. Let cool 5-10 minutes before serving.
3. While the oatmeal is cooling, prepare the toppings. Stir together the peanut butter and honey in a small glass dish. Slice the oatmeal into squares and serve topped with banana slices and drizzled with peanut butter and honey. 

Peanut Butter Banana Oatmeal

There aren’t many combinations that make me grin the way peanut butter and bananas do, so Peanut Butter Banana Oatmeal is an absolute win with me. Made into a sandwich, piled onto warm toast, chocolate-dipped banana bites with a smear of peanut butter on them? Pure heaven!

Peanut Butter Banana Muffins, Caramel Peanut Butter Banana Milkshakes, Peanut Butter Banana Ice Cream, and even Peanut Butter Banana Green Smoothies, they’re all delicious.

For some more of our all-time breakfast favorites, Banana Pancakes and Banana Waffles just wouldn’t be the same without a generous topping of peanut butter. We love to layer this Slow Cooker Peanut Butter Granola into Peanut Butter Banana Yogurt Parfaits for an easy weekday breakfast.
