Blueberry Banana Baked Oatmeal Recipe


  • 2 1/4 cups old-fashioned rolled oats
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1 cup ripe mashed bananas (about 2 large bananas or 3 medium bananas)
  • 3/4 cup milk*
  • 1/4 cup honey
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup fresh or frozen blueberries*


  • Preheat oven to 350°F. Spray an 8-inch square baking pan well with non-stick cooking spray and set aside.
  • In a large mixing bowl, mix together the old-fashioned rolled oats, baking powder, cinnamon, and salt. Set aside.
  • In a separate mixing bowl, mix together the mashed banana, milk, honey, egg, and vanilla extract until fully combined.


  • Add the wet ingredients to the dry ingredients and mix until everything is well incorporated. Gently fold in the blueberries.
  • Pour the mixture into the prepared baking pan and smooth it out into one even layer.


  • Bake at 350°F for 30-40 minutes or until the top is set and lightly golden brown. Mine is usually perfect around 35-36 minutes.
  • Remove from the oven and allow to cool for 10-15 minutes. Slice and serve warm, or cool completely, cover tightly, and refrigerate until ready to enjoy.


  • Store leftover baked oatmeal in an airtight container in the refrigerator for up to 5 days.
  • Freezing Instructions: This will freeze well for up to 3 months, thaw overnight in the refrigerator and warm in the microwave before serving.
  • Milk: I used unsweetened almond milk, but any kind of milk will work in this recipe.
  • Blueberries: If using frozen blueberries, make sure to gently stir them in so they do not bleed their color and turn the oatmeal purple.


  • This baked oatmeal can also be frozen for up to 3 months! Just thaw overnight in the refrigerator and warm in the oven or microwave before serving.

  • If desired, you can substitute quick oats for the old-fashioned oats. You’d use the same amount of oats as listed in the recipe card below. 
  • You can also turn this into muffins. You’d likely need to bake them for 20-25 minutes.



In one bowl, whisk together the wet ingredients. In another bowl, whisk together the dry ingredients. Add the wet mixture to the dry one and mix them together. Add the blueberries slowly and carefully.


Place the mixture in a baking dish that is 8 inches square. Bake for 30 to 40 minutes, or until the top is set and has a light golden brown color. Around 35 to 36 minutes is when mine is usually done.


After 10 minutes, cut the blueberry banana baked oatmeal into squares. The texture of baked oatmeal is kind of soft and chewy, but it’s so tasty that even picky eaters will love it. Blueberry Banana Baked Oatmeal is one of my favorite things to eat. I like to put it on top of Greek yogurt. You can also put some pure maple syrup, almond milk, or fresh fruit on top and enjoy it even more.



I’ve tested this recipe with frozen blueberries and they work great too, which means that you can make this recipe all year round. If you are using frozen blueberries, just make sure to gently mix them in so they don’t turn your oatmeal purple.  You can also change up the berries in this recipe and use your favorite or whatever you have on hand.


This healthy baked oatmeal will last up to 5 days in the fridge.
