Peanut Butter Baked Oatmeal is like having a breakfast fairy that simplifies your busy mornings. This recipe is easy to make and the perfect meal prep breakfast!
Grab a few pantry staples, whip up this delicious dish in 10 minutes, throw it in the oven, and voila! You’ll start your day with a hearty and satisfying meal without breaking a sweat.

I’ll be honest, I’ve never been the “steam-y bowl of oatmeal” type. Oats in cookies? Always. A spoonful of hot mush? Hard pass. But after a dozen test batches (my husband, mother and neighbors were all were nice enough to provide good feed back), this peanut butter banana baked oatmeal won me over in a big way.
Here’s why I trust it enough to share with you:
- Tried and true texture. Baking turns humble oats into something closer to a soft breakfast bar with crispy, toasty edges. If regular oatmeal feels gummy to you, this will be a game changer.
- Balanced nutrition. Thanks to natural peanut butter, two whole bananas, and a couple of eggs, each square packs protein, fiber, and potassium. Fuel that actually keeps you full until lunch.
- Meal prep friendly. I ran the recipe through my old meal-assembly playbook: mix, bake, cool, slice, and stash. The pan chills overnight, and in the morning a quick microwave reheat brings back that fresh-from-the-oven coziness in 30 seconds.
- Family approved. Between busy weekday mornings and grab-and-go snacks after soccer, my crew devoured every test tray. Even my “I don’t do breakfast” teenager grabs a square on the way out the door.
Pro tip: While you’re in prep mode this weekend, whip up a batch of my peanut butter breakfast cookies, too. They travel well, earn rave reviews, and keep the whole family on schedule.
Ingredients

Recipe Notes
- Milk – Any milk will work to help soften the oats. I used almond milk.
- Maple syrup -Use pure maple syrup to sweeten the oats. You can also use honey.
- Peanut Butter – Smooth peanut butter without added sugar is ideal; look for natural peanut butter, usually just peanuts. A drizzle of peanut butter after the oatmeal bakes is delicious!
- Rolled Oats – Stick with rolled oats for this recipe. I do not recommend making it with quick oats or steel-cut oats.
