Blueberry oatmeal muffins

Hearty Texture. Not Flat. Not Squishy.

These blueberry oatmeal muffins have a hearty, wholesome texture because they’re made with oatmeal. Oats in muffins and oatmeal muffins are two completely different things. Oats are a dry ingredient; oatmeal is a wet ingredient. Today we’re making OATMEAL muffins.

These oatmeal muffins are:

  • satisfying
  • simple to make
  • warm + buttery
  • made with oats
  • sweetened with honey
  • bursting with blueberries

Testing this recipe was massively interesting. If you look at this next photo, you can see the difference. The squat muffin on the left was wet and spongey. The tall muffin on the right was hearty, delicious, all the glorious thing I listed above. What’s fascinating is that there is only 1 small difference between the two and that difference is 20 minutes of time!

How to Make Oatmeal Muffins

There are only 2 main steps before baking the muffins.

  1. Soak the oats in milk for 20 minutes: By doing so, the oats will soak up a lot of the milk. This creates a thicker and creamier muffin batter. The soaked oats won’t actually be the consistency of oatmeal because we aren’t cooking the two together. Rather, the oats will rise to the top of the bowl.
  2. Mix the batter together: Mix the dry ingredients in 1 bowl and the wet ingredients in another bowl. Mix together, then add the soaked oats & milk. That’s it, you’re done.

Then it’s time to bake the blueberry oatmeal muffins!

Ingredients for Blueberry Oatmeal Muffins

Nothing but basics here! Besides oats and milk, you’ll need flour, butter, honey, egg, and a little cinnamon and vanilla extract for flavor. I encourage you to use melted butter instead of oil or a lower fat ingredient. The muffins lost a lot of flavor without butter and when I tested them with applesauce, they tasted rubbery and dry.

If you’re more of a muffins-should-have-chocolate person, go ahead and replace the berries with a cup of chocolate chips. Consider this recipe your oatmeal + honey master muffin recipe and play around with different flavors and add-ins!

Did you know? The thicker the muffin batter, the taller and puffier the muffin will be. A thick batter combined with my initial high temperature trick in the recipe below guarantees tall muffin tops.

These blueberry oatmeal muffins are simple, wholesome, and satisfying. Made with blueberries, oats, and zero refined sugar, you can feel good eating one or two, or three!


  • 1 cup (240ml) milk
  • 1 cup (80g) old-fashioned whole rolled oats
  • 1 and 1/4 cups (156g) all-purpose flour (spoon & leveled)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (115g) unsalted butter, melted and slightly cooled
  • 1/2 cup (120ml) honey
  • 1 large egg, at room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup (190g) fresh or frozen blueberries (do not thaw)


  1. Combine milk and oats. Set aside for 20 minutes so the oats puff up and soak up some moisture. This is crucial to the recipe! (I usually melt the butter now so it has a few minutes to cool.) Don’t do this the night before as that’s too long for soaking. If you find the oats haven’t soaked up any moisture after 20 minutes, give it a stir and wait 10 more minutes.
  2. Preheat oven to 425°F (218°C). Spray a 12-count muffin pan with nonstick spray or use cupcake liners.
  3. Whisk the flour, baking powder, baking soda, cinnamon, and salt together in a large bowl until combined. Set aside. Whisk the melted butter, honey, egg, and vanilla extract together in a medium bowl until combined. Pour the wet ingredients into the dry ingredients, stir a few times, then add the soaked oats (milk included, do not drain) and blueberries. Fold everything together gently just until combined.
  4. Spoon the batter into liners, filling them all the way to the top. Top with oats and a light sprinkle of coconut sugar, if desired. Bake for 5 minutes at 425 then, keeping the muffins in the oven, reduce the oven temperature to 350°F (177°C). Bake for an additional 16-17 minutes or until a toothpick inserted in the center comes out clean. The total time these muffins take in the oven is about 22-23 minutes, give or take. (For mini muffins, bake 11-13 minutes at 350°F (177°C).) Allow the muffins to cool for 5 minutes in the muffin pan, then transfer to a wire rack to continue cooling.
  5. Muffins stay fresh covered at room temperature for a few days, then transfer to the fridge for up to 1 week.


  1. Make Ahead Instructions: For longer storage, freeze muffins for up to 3 months. Allow to thaw overnight in the refrigerator, then bring to room temperature or warm up in the microwave if desired.
  2. Milk: I tested the blueberry muffins with unsweetened almond milk, but any milk, dairy or nondairy, can work.
  3. Oats: I recommend whole oats. Steel cut oats work as well, but avoid quick or instant oats. They’re too thin and will dissolve in the batter as it cooks.
  4. Flour: For best taste and texture, I recommend all-purpose flour. If you try whole wheat flour, let me know how they turn out!
  5. Oil: You can use canola, vegetable, or melted coconut oil instead of the butter, but the flavor will change. I strongly recommend melted butter.
  6. Sugar: You can use 1/2 cup maple syrup, coconut sugar, or packed light or dark brown sugar instead of honey.
  7. Why the Initial High Temperature? The hot burst of air will spring up the top of the muffin quickly, then the inside of the muffin can bake for the remainder of the time. This helps the muffins rise nice and tall.
  8. Nutrition: Using SparkRecipes calculator and calculated using unsweetened almond milk these muffins come out to 205 calories, 9g fat, 28g carbs, 2g fiber, and 4g protein each.

Blueberry oatmeal muffins


  1. I just discovered your web site, as I was looking for an oatmeal blueberry muffin recipe. I made these today, and this recipe is a keeper! The muffins came out tender and tasty. I will be returning to your web site to try scones next. I love your clear explanations and tips. Thank you!

  2. I was sceptical these would turn out based on the batter…but I’m glad I took the leap of faith! My son cannot get enough of them and I am okay with it. I will be using this as my muffin base here on out.

  3. I love muffins and am always looking for a great low fat recipe. Thanks for the Notes, those helped. I used gluten free flour, 1/2 maple syrup and 1/2 honey. I also subbed unsweetened applesauce for the butter and left out the blueberries. They came out great! Delicous!
    Thank you!

      1. I used 1/4:cup less flour and instead 1 1/4 cup oats .
        3/4 cup,Greek,jogurt 1/4 cup milk

  4. Kudos! These are full of blueberries and are not too sweet to serve for breakfast. My husband is vegan, so I substituted 1/4cup unsweetened applesauce instead of the egg; I used Earth Balance spread instead of the unsalted butter and cut the salt to 1/4 tsp. I used 3 minute steel cut oats (Quaker product) soaked in 1 cup unsweetened soy milk. The oats disappear into a nice texture. Oh, I made this into 18 nicell shaped muffins. When I run out of blueberries I might try this with other fruits.

  5. My daughter (4years old) and I adore these muffins. I’ve been making them since the first day you posted the recipe and they are perfect every time! I almost always sub with vegetable oil and banana instead of butter and eggs as we love the extra natural sweetness from the banana! Love this recipe and will always make this at least monthly! A must try for sure! ❤️

  6. I love these muffins. I have been looking for a blueberry muffin recipe and I found it. I made this using whole wheat flour and they are delicious.

  7. I’m so sad I just made these and the flavor is good but they didnt fluff up n we kinda heavy n dense kinda doughy. Not sure what I did wrong. Soo sad

    1. Did u soak the oats in the milk? I warmed my milk up and it worked like a charm. My muffins are baking right now and they have risen nicely. Can’t wait to eat them!

  8. Hi! I just discovered your website. Those muffins look delicious. I don’t eat gluten, do you know what would be the best replacement for the all-purpose-flour?

    1. Hi Hilda, I don’t have much experience baking with gluten free flour but many readers have reported back that they sub all purpose gluten free flour with success!

  9. Oat Flour works great. I put them in at 375 degrees for the total time. Great with organic bananas as a change. You can add maple syrup to the batter, if you do not mind the calories. Wonderful blueberry recipe!

  10. These muffins were very good. My husband said they were the best I have made. I have used another one of your blueberry muffin recipes in the past which were yummy also. I used a combination of whole wheat flour and AP flour and no issues. I find a 50/50 ratio works well. I did use brown sugar as the sweetener.

  11. These muffins were moist and yummy! I think soaking the oats is a great way to do it. Only problem is the batter was enough for 6 muffins, not 12. I’d double the recipe next time

    1. Hi Jamesa! Were you using a standard 12-count muffin pan or a jumbo muffin pan? This is a considerable amount of batter and yields more than 6 regular size muffins. So glad that you enjoyed them. Thanks for trying the recipe!

  12. I have made these muffins many times, following the recipe exactly, and I love them. Today I wanted to try whole wheat flower, and I might like them even more. It adds an extra heartiness to them. I also ran out of honey, and used about 1/4 cup honey & 1/4 cup brown sugar. They were delicious!

  13. I left my muffins to cool a few minutes too long in the pan and now the bottoms are just a little bit soggy, is there a way to salvage them?

  14. The muffins turned out moist and delicious! I e made them several times, sometimes with blueberries , sometimes with a cup of mashed banana if i have no blueberries on hand.
    I only use 1/4 cup honey and I feel that is plenty. My elderly mother is an extremely picky eater but loves these muffins.

  15. Hi, Sally.
    Does the change in temperature during the baking process flattens the muffin?
    If I were to just stick to one temperature, what would be best and how long?

    1. Hi Loshinee! Actually, exactly the opposite! The initial hot burst of air actually lifts the muffin tops right up– creates a lovely tall muffin. Let me know if you try it!

  16. This recipe is a winner! I made it almost exactly as you listed, only using brown sugar in place of honey. I will use honey next time to compare if there is a difference. I also like to add flax seed to my breads and muffins, but that shouldn’t change the taste or consistency. I love how you lay out your recipe, instructions and information. Very helpful! Thank you for the yummy recipe. We have a new go-to muffin recipe.

  17. This is my mom’s and my new baking addiction! I added some ground cardamom to make the taste a little more autumnal and we used half whole wheat flour and half all-purpose and they turned out delicious. Thanks for the great recipe!

  18. Oh Sally, I really thought I messed up! I started to make them last night and had soaked my oats and got called away. I refridgerated and continued tonight and they still turned out great!

  19. Wheat flour- I did use half whole wheat flour and half all purpose. These were very delicious! Thank you for this recipe!

  20. Hi Sally
    I use wholewheat flour and quaker oats instant oatmeal (coz I didn’t have whole oats in hand. They turned out tall and great. Thanks for the healthy recipe as I was looking for dessert recipe without sugar for my hubby.

  21. So I have made these twice. Both times with whole wheat flour, the first time with vegan butter (just trying to use it up since we don’t usually have it) and coconut milk and the second time with milk and butter. Both times they were delicious, super moist and toddler approved (with a chocolate chip on top of course.) I will definitely keep this recipe around!

  22. You recommend oil, but it’s not listed in the recipe. Has me nervous as I read it immediately after putting muffins in the oven

  23. I was looking for a blueberry muffin recipe without sugar. Your recipe turned out great. I used whole wheat flour instead of all purpose flour. It turned out great-soft, moist and perfect for breakfast. I will pin it for future use.

  24. Oh my! This muffins surpassed all my expectations! They are moist and delicious! Definitely my new go-to oatmeal and everything muffin recipe!!

  25. Delicious! I made them plant based so I substituted a flax egg instead of regular egg, used oat milk and earth balance for the butter. I also used organic spelt flour.

  26. Hi there! Just bought all the stuff to try making these muffins for my breakfasts this week! So excited and I see a lot of positive comments. Is the nutrition facts 200 calories per muffin? Thanks!

    1. Hi Jen! I haven’t tried it. I fear the muffins would be too wet, so it could take some adjusting. Let me know what you try!
