What is baked oatmeal?
Primarily, baked oatmeal is a baked oat custard. What is a custard? Custard is sweetened milk thickened with eggs. Baked oatmeal combines a thin custard with oats. It is a versatile breakfast dish that is healthy, hearty, and satisfying.

Banana Bread Baked Oatmeal Recipe Ingredients:
- Bananas – Use only ripe bananas.
- Old Fashioned Rolled Oats – I designed this recipe using old fashioned oats.
- Maple Syrup – This recipe calls for maple syrup versus sugar.
- Pure Vanilla Extract
- Avocado Oil – I love avocado oil for its neutral flavor and healthfulness. Liquid coconut oil is an effective substitution.
- Eggs – Two large eggs, at room temperature, are necessary to create this custard-like dish.
- Oat Milk – I love using oat milk for recipes revolved around oats. I find it amps up the oat flavor. You can substitute with almond or whole milk as well.
- Ground Cinnamon
- Salt
- Baking Powder
- Chopped Pecans – You can substitute with chopped walnuts, or omit the nuts all together.
*Chocolate chips would be a lovely addition to this baked oatmeal recipe as well.

How to make Banana Bread Baked Oatmeal:
- Preheat the oven to 350 degrees F. Grease a 8X8-inch baking dish, set aside.
- In a small bowl, toss together the oats, chopped pecans, ground cinnamon, salt, and baking powder.
- In a stand mixer with the paddle attachment, mash the bananas on medium speed. Next, add the avocado oil, eggs, milk, vanilla extract, and maple syrup, mixing until well incorporated.
- The last step is to add the oat/nut blend and mix until everything is combined.
- Pour the mixture into the prepared dish and bake for 35-40 minutes, or until set and golden brown. If you like your baked oatmeal a little more on the firm side, like myself (and as pictured), bake for a little longer.
- Allow the baked oatmeal to cool before slicing into 6 squares.
*Store in an airtight container in the refrigerator for up to 5 days.
