Why You’ll Love This Recipe

  • It’s so easy to make – it only takes about five minutes to prep this dish!
  • Oats are one of the healthiest grains, and they’re a great source of fiber, vitamins, minerals, and antioxidants, and they keep you satisfied until lunch. Health benefits include lowering blood sugar levels, weight loss and management, and reducing the risk of heart disease.
  • You can add this recipe to your list of make-ahead breakfasts. The leftovers keep in the refrigerator for several days as a quick breakfast throughout the week. Simply reheat a portion in the oven or microwave with a splash of milk.
  • If you’re planning to serve this for breakfast or brunch to a large crowd, you can make it the night before, keep it covered in the fridge, and bake it in the morning before serving. It makes 8 servings, and you can even double it if need be.

Chef’s Tips

  • The best oats for baking are rolled oats; I find them the best! They’re whole, flattened oats that have a nice chewy texture. Quick oats are similar, but they’re cut into smaller pieces, so their texture is more delicate when baked. Old-fashioned oats will result in a heartier texture.
  • You can make this breakfast vegan by substituting 2 flax eggs for the eggs, using coconut oil instead of butter, and using a plant-based milk.

9 servings

Ingredients

  • 3 cups rolled oats
  • ⅔ cup maple syrup
  • 2 teaspoons ground cinnamon
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • ½-¾ cup milk of choice ½ cup for firmer oatmeal, ¾ for less-firm oatmeal
  • 2 large eggs
  • ½ cup melted butter or refined coconut oil, plus more to grease baking dish
  • 3 teaspoons vanilla extract
  • 1 ½ cups blueberries fresh, or thawed & drained if frozen
InstacartGet Recipe Ingredients

Equipment

  • Large mixing bowl
  • Silicone spatula
  • 9×13 baking dish

Instructions 

  • Preheat oven to 350° Fahrenheit. Lightly grease baking dish with butter or coconut oil. Set dish aside.
  • Add oats, maple syrup, cinnamon, baking powder, salt, milk, eggs, melted butter, and vanilla extract to large mixing bowl. Mix thoroughly until all ingredients are fully incorporated.
  • When oatmeal mixture is just combined, add blueberries and gently fold blueberries into oatmeal mixture, being careful not to overstir.
  • Transfer mixture into 9×13 baking dish. Gently spread oatmeal mixture out across bottom of baking dish in one even layer, making sure to press mixture into corners of dish.
  • Place baking dish in preheated oven. Bake oatmeal mixture 30 minutes, then check doneness. Continue baking as needed, checking doneness every 1 to 2 minutes, until top of baked oatmeal is golden brown and crisp. Bake time shouldn't exceed 45 minutes total, but times will vary from one kitchen to another.
  • When oatmeal is fully baked, carefully remove baking dish from oven. Let cool slightly, then slice baked oatmeal into 9 equally-sized bars. Serve warm.

Notes

Blueberries: If using frozen blueberries without defrosting, increase cook time by 5 minutes or so. Frozen blueberries will release moisture that may affect the texture of the baked oatmeal.
Leftovers: Let baked oatmeal cool completely, then transfer leftover bars to airtight container. Refrigerate up to 5 days. Reheat individual bars in microwave before serving, or serve chilled.
Gluten Intolerant: If you’re gluten-intolerant, be sure to check that the oats are GF-certified.

    Of course I can’t find my 9×13 pan, and I had a bad mishap with a different recipe lately when I used the wrong size and ruined my meatloaf :(. Do you know if I make these in a muffin pan or something what the bake time would be? Sorry, I’m a novice but these look great.

      I can’t say for sure what the timing would be, but you could always try it at 350 degrees for 20 minutes and then 5 minute increments after that! Let me know how it goes if you do it!

      I tried them in a muffin tin (with paper wrappers). They were a bit greasy on the bottom from the coconut oil, but overall they held up well. I also put them in the freezer and pulled out a few every morning. It worked, but I think next time I’d rather just cut the big bake into sections.

        I would definitely try that! That’s how we tested them so we can never say for sure if they’ll work in a different baking container 🙂

    Would this work with just one egg?

      One egg won’t hold it together as well, you could use just one egg but it will end up being more like granola then a solid sheet!

    This is really good! But mine came out very crumbly, any idea how to avoid this for next time? I followed the recipe exact, used butter instead of coconut oil. Thanks!

      The coconut oil is a little bit of a better binder than butter, that could definitely be your issue!

    The taste is wonderful, I did think it spread a little thin. Did I do something wrong?

      You could always try beating the egg a little more, so it rises higher. It’s not supposed to be super thick, so you could have done it perfectly!

    Delicious! I used flax in place of egg, as you suggested, with great results. I also substituted fresh raspberries in place of blueberries.

      I used bananas instead of eggs, and also used fresh raspberries. To top it off I added a lemon drizzle. I DO NOT REGRET IT! So good!

    I made this last night for this morning. I used 1/4cup of applesauce instead of butter and its delicious. A little crumbly but still taste great! Love this recipe

    Just a quick question for clarification purposes. The first part of your article mentions using brown sugar in your baked oatmeal recipe but the recipe doesn’t list brown sugar. Do you use the maple syrup instead of the brown sugar?

      You’re so right – that’s an error. There is no brown sugar, just maple syrup. The recipe has been updated. Thank you for noticing that!

        Whoops! Brown sugar is *still* listed in the “how to make…step-by-step section.
