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.

Description

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!


Ingredients

  • 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)

Instructions

  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.

Notes

  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.

  1. I tried the recipe, all good. The only thing I noticed is that it wasn’t as sweet. I would want to add more honey or sugar to balance the level of sweetness.

  2. Great recipe, will definitely be using again. I feel like this would be a good base for most types of muffins. I decided to make this at about 9pm on a Tuesday & unfortunately I didn’t have milk fear not for the internet is amazing & I read that you can substitute equal parts sour cream in place of milk. I gave it a go but I did thin the sour cream out with water. It worked great! The only thing I’d change would be more blueberries & topping the muffins with either Demerara sugar or a cinnamon oat streusal topping.

  3. I used white whole wheat flour from king Arthur brand flour and I used strawberries instead of blueberries and they were delicious! Very soft and fluffy. My husband and I had them for breakfast for a week!

  4. This was the first time making this recipe, they came out very good but a little bit more dense than I was expecting. My oats ended up soaking for 40 minutes instead of 20 (I have a 3 month old that needed me!), is it possible that I over-soaked them? I also used King Arthur unbleached all purpose flour, I didn’t sift, just measured. The baking powder I had on hand was double acting, not sure if any of these factors affected the recipe. Thanks!

    1. Hi Megan, It certainly could have been simply soaking the oats for a long time – especially if you noticed that there wasn’t much liquid milk left. I totally understand a baby not allowing us to stick to exact wait times and I’m glad you enjoyed the flavor of these anyway! 🙂

  5. Great, fluffy muffins! I left out the blueberries, since I may kids are not fans. This recipe is a perfect base to customize! I may try chocolate chips next time!

  6. Made these for breakfast this morning and my kids loved them! I used maple syrup, original Blue Diamond almond milk (not unsweetened) and the mixed frozen berries we had in the freezer. Filling and delicious! Thanks for sharing! 🙂

  7. I only had quick oats on hand. I used dried cherries and pumpkin flavored condensed milk. I added a pinch of nutmeg and ginger. The muffins were wonderful, absolutely delicious. I will buy the rolled oats so as not to miss out on the texture. Perhaps, with quick oats they need soak in milk 20 min, but 10 or 15?

  8. I done this recipe 3 times this week already! Very nice. Kids love them. I just did frozen cherries and mini chocolate chips. It’s so versatile. Thank you.

  9. These muffins are so delicious! I didn’t have blueberries so I substituted with chocolate chips, which added a touch of sweetness. I am also trying these out for lactation purposes… any excuse for mom to bake :).

  10. Very good! I added chia seeds, unsweetened applesauce and dried cranberries. They look great, taste good but I’m tasting piping hot right from oven. Should comment again when cool!!!

  11. Followed recipe exactly as instructed. They came out perfect!! All of Sally’s recipes that I’ve made have come out great. “IN SALLY WE TRUST!” LOL. Thank you for another awesome recipe! (:

  12. Best recipe for cupcakes I’ve used. The oats soaked in milk made the cupcakes really soft and delicious. They came out so light and fluffy. I used strawberries and white chocolate buttons in them.

  13. I am patiently waiting for them to cool to remove them from the muffin tin they look perfect! My Alexa echo dot has given me the giggles reminding me that my” muffin timer” is done lol. My son had to inform me of funny muffin memes. Baking is fun!

  14. I made these today using freshly ground hard white wheat. I also only had salted butter so I didn’t add any salt. I warmed the milk before adding the oatmeal because I didn’t want to wait as long for it to soak. They came out excellent. The texture is perfectly light and fluffy, yet the taste is very hearty. Some nuts would be a good addition. I added a sprinkling of brown sugar and oats to the top, and they were beautiful. They weren’t quite sweet enough for my kids. Next time I’ll try more of a strusel topping for them.

  15. Just wanted to say I love this recipe- super easy to make and the whole family loves them. Added bonus- I don’t feel guilty serving them to my toddler because they have no refined sugar!

  16. I made these yesterday and had two for breakfast this morning – DELICIOUS! I added a little almond extract with the vanilla (we love the flavor combo of the two). It’s true these aren’t super sweet muffins, but even though I have a huge sweet tooth I found these to be perfect with my strong coffee. If you would like to bump up the sweet factor, a little Sugar in the Raw on top would likely do the trick. I’m going to try another batch later this week with raspberries and orange zest!

    Seriously so freaking good. I wish I had another one right now to snack on.

  17. I just made these tonight for the first time. I ended up using almond milk, adding pecans and used the large muffin pan to make 6 since I misplaced my regular muffin pan. The timing in the oven ended up being about the same for me since I live at elevation. These are amazing and I love that they’re not overly sweet. I will keep these in the freezer and they’ll be perfect for mornings when I’m on the road to a hike or bike ride. I will use this recipe over and over again and just play with the add in ingredients!

  18. This is my 3rd time making these and they are always so good. I usually change up a few things in the recipe, doing half wwf but i’m currently all out. This time I used maple syrup, and subbed applesauce for half of the butter, and used almond milk. Yum!!

  19. These were very good. I used a combination of flour, wheat flour and flaxseed meal. Trying to get more flax and oat into our diet. I’ll probably sugar up the tops better next time but it really doesn’t need it.
