Why you’ll love this recipe
- Incredibly tasty: This oatmeal bake comes out of the oven with the best taste and texture! It’s perfectly chewy, soft, and a little custardy with a slightly crisp topping. It tastes just like dessert!
- Healthy & filling: A slice of this sweet breakfast casserole is super satisfying, nutritious, and will keep you going for hours. It’s packed with plenty of protein, fiber, and healthy fats to nourish your morning and leave you feeling satisfied.
- Quick & easy to make: Nothing complicated about this recipe! All you need is 10 minutes of hands-on time to mix all of the ingredients in one bowl.
- Great for meal prep: I like making this at the beginning of the week, portioning it out into squares, and reheating it in the morning for a quick ready-to-go breakfast. It’s also freezer-friendly!
Ingredients you will need
This oatmeal bake is made with simple ingredients that you likely already have on hand. You’ll need:
- Flax egg: I combined 2 tablespoons of ground flaxseed and 1/3 cup warm water to replace two eggs in this recipe.
- Quick oats: For the best texture, I recommend quick oats in this particular baked oatmeal recipe. Use gluten-free oats as needed.
- Baking powder: To help it rise a little and not turn out completely flat.
- Salt: You always need just a bit of salt in a sweet dish like this to balance the flavor. Sometimes I skip this though.
- Flavor makers: Pumpkin spice mix and vanilla extract add warmth and cozy flavor.
- Bananas: This ingredient makes this dish perfectly moist and sweet. Be sure to use very ripe bananas!
- Peanut butter: Such delicious flavor! Feel free to use crunchy, if you like a little extra nutty crunch in your oatmeal.
- Honey: To naturally sweeten the dish. Maple syrup or agave would work great as a substitute.
- Milk: I like to use 2% milk, but you can use any milk you’d like.
- Peanuts: The addition of chopped unsalted roasted peanuts really takes this baked oatmeal to the next level. However, you can omit it if preferred.

This baked oatmeal recipe is super easy to throw together! It’s really just a matter of stirring the ingredients together in one large bowl, pouring the mixture into a pan, and baking it up!
For full, printable instructions, reference the recipe card at the bottom of the post.
- First, you need to Prep: Preheat the oven to 350 degrees and grease an 8×6-inch baking dish with a tiny bit of coconut oil.
- Next, make the flax egg: In a small bowl, whisk the ground flaxseed and water and set aside.
- Combine dry ingredients: In a large bowl, combine the oats, baking powder, salt, and spice mix.
- Then, mash bananas: In a small bowl quickly mash the bananas and add them to the bowl with the oats.
- Mix wet and dry ingredients: Add in all the remaining ingredients, together with the flaxseed mixture, and stir well to incorporate.

Recipe Tips
- Feel free to substitute the flax eggs with 2 beaten eggs and add them at the same time as you would add the flax eggs to the other ingredients.
- You can make your own pumpkin pie spice! Simply combine ¾ tsp cinnamon, ¼ tsp nutmeg, and ½ tsp ground ginger, or just use 2 teaspoons of ground cinnamon to replace the spice mix.
- Make this vegan baked oatmeal by replacing the honey with maple syrup.
- Don’t have ripe bananas? You can easily ripen your bananas by wrapping them in foil and popping them in the oven at 350 degrees for 10 to 15 minutes.
Frequently asked questions
Whereas cooking oatmeal on the stovetop or in the microwave gives it a creamy porridge consistency, baking oatmeal gives it a chewy, soft, and creamy texture, almost like bread pudding.
Baked oats are just as healthy as regular oatmeal to enjoy for breakfast. This recipe includes nutrient-rich ingredients like oats, healthy fats, and naturally sweetened fruit.
Even though they are cooked and you may be tempted to leave them out overnight, I highly recommend you store them in a container in the fridge since most are made with dairy and milk.
Storage recommendations
- Storing leftovers: Place any leftover baked oatmeal in an airtight container or plastic, in the fridge for up to 4 days.
- Freeze: Place individual servings in an airtight, freezer-safe container or freezer-safe bag for up to 3 months.
- Reheat: Place individual slices in the microwave for about 1 to 4 minutes, depending on whether it’s at room temperature or frozen.
