Blueberry Banana Baked Oatmeal Muffins


There’s nothing better than a classic blueberry muffin, and while we love the classic tender crumbly muffins we know we can’t indulge in them often. These oatmeal muffins have the same warm spices and flavors with the heart healthy oatmeal filling. Instead of cake you’re going to have a well balanced breakfast that will keep you full for longer, made with rolled oats and bananas, this is the perfect healthy option with the hint of dessert flavors.

These hearty breakfast bites are packed full of flavors you’ll love like vanilla, blueberry, old-fashioned oats, and honey. The oats, blueberries, and other ingredients pack the muffins full of fiber, quality protein, and antioxidants to get you going in the morning!

Easy muffin cups are the perfect make-ahead breakfast! They only take a half-hour to make so you can easily make it a double batch, and freeze the second one to have ready for busy mornings.

If you’d rather use steel-cut oats instead of the rolled oats we have in the recipe you can. Steel-cut oats have even more fiber and are slightly lower in calories. However, they take longer to absorb water, so your baking time will be longer.

Dietary Restrictions

Easily adjust this oatmeal recipe to match your dietary needs.

  • Gluten Free: Fortunately, these blueberry muffins are already essentially gluten-free. The oatmeal recipe doesn’t include any all-purpose flour, whole wheat flour, or any other grains that would typically cause a problem. Pure oats are already gluten-free. Just check the label on the oats you buy to make sure they aren’t cross-contaminated. 
  • Vegan: Make your blueberry oatmeal vegan by substituting for the milk and egg. Use any dairy-free milk like almond milk, oat milk, or soy milk in the oatmeal. You can use ¼ cup unsweetened apple sauce to substitute for the egg. Or if you don’t like the idea of applesauce with blueberry, add another mashed banana to replace the egg.

Tips for the best Blueberry Oatmeal Muffin Recipe

1. Don’t over-mix your ingredients. When you start to mix your oats and other dry ingredients with the wet ingredients in this recipe, you might be tempted use an electric mixer to go faster. There’s no need for that. Just stir the baked oatmeal ingredients by hand until just combined, and then it evenly into muffin cups. 

2. Rinse frozen blueberries. You can use either fresh blueberries or frozen blueberries for this recipe. If you use frozen blueberries they might turn your blueberry muffins blue. To stop this rinse the blueberries in water before putting them in the oatmeal. 

3. Test if your Baked Blueberry Muffins are done with a toothpick. This muffin recipe should only take 20 minutes to bake. To make sure they’re done baking when your timer goes off, insert a toothpick into the center of a muffin. If the toothpick comes out with wet oatmeal on it let the blueberry oat muffins bake a little longer.

  • Add-ins: There are a variety of mix-ins you can add to this baked oatmeal recipe to change the flavor and texture of the muffins. Some easy ones to try are raisins and almonds. You can mix the raisins or almonds with the blueberries or exchange them. You could also try adding different berries to your muffin recipe like sliced strawberries or raspberries.
  • Maple Syrup: The flavors of baked blueberry oatmeal and maple syrup are breakfast classics that pair wonderfully. Many recipes for oatmeal muffins use maple syrup as the sweetener. To exchange the honey in this recipe for maple syrup, you’ll need to mix 3 tablespoons of maple syrup with 2 tablespoons of sugar. Add that to the dry ingredients when you would normally add the honey.
  • Greek Yogurt Bowl: If you have leftover blueberry Baked Blueberry Oatmeal Muffins you need to eat, but you aren’t in the mood for muffins, you can crumble one over a bowl of low-fat or fat-free Greek yogurt for a whole new breakfast. It’s similar to eating granola and Greek yogurt. Feel free to add more fresh blueberries and honey to your taste. 
  • Chocolate Chip Muffins: Blueberry muffins might be the most popular muffin recipe, but chocolate chip muffins are a close second. Switch out the blueberries in your muffins for chocolate chips to make oatmeal chocolate chip muffins. You can even make a double batch of oatmeal, and divide it in half for one batch of blueberry muffins and one of chocolate chip. Then have the perfect breakfast with one chocolate and one blueberry muffin.

  1. I made these last night. Waaaat too much liquid – I double checked the recipe to see if I missed flour or something, but nope. They turned out goopy and sticky. Left then in an extra 10 mins and it made no difference. You may want to make some adjustments to this, sadly.

  2. 1 star
    Would not recommend. Terrible. Either there is a missing ingredient or the measurements are off, but these definitely did not turn out.

  3. 4 stars
    Not quite what I was expecting but still very yummy. They came out less like muffins, and more like gooey, baked, oatmeal. I had to bake for a bit longer and I added a tablespoon of flour to help it be less runny but the edges and top came out crispy enough to hold together.

  4. 3 stars
    Metric converter is incorrect, meaning I used way too much milk. Such a shame as it seems like a good recipe. Unfortunately my muffins are flat, stodgy and still uncooked despite 45 minutes in the oven…

  5. 5 stars
    A perfect ,healthy muffin. They have an almost custard like texture and sweet enough for a dessert treat or snack. Great on the run breakfast with a bit of yogurt., Keeps me full for a long time.Gluten free to boot!

  6. 1 star
    Not a huge fan of these…I kept wondering when the flour comes in until I noticed it wasn’t listed as an ingredient. I decided to trust the recipe…I baked them for about 25 mins. They are golden brown but mushy without structure.

    1. Was this right after they came out of the oven? Or after they’d cooled for a few minutes? They should’ve held together really nicely for you. Would love to help.

  7. 2 stars
    Was a fail for me. Ended with breakfast oatmeal with fruit. Knew it was iffy without some kind of flour, maybe grind the oats
    and mash the banana, chop the banana was vague, fine or chunky? Gonna freeze and pop out and add a little water and heat for cereal. Completely cooling in the pan didn’t help

  8. 5 stars
    Mine turned out really well for a first attempt. I’ll be making another batch soon. I see clearly what your objective is; these aren’t flour and sugar muffins rather a healthy alternative. Looking forward to trying out more of your recipes. Great work, thanks from a country cottage in England.
