Blueberry oatmeal muffin

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. If you want oat muffins instead of oatmeal muffins, you’ll love these applesauce muffins. Today we’re making OATMEAL muffins.

Oatmeal muffins are also different than baked oatmeal (like chocolate chip baked oatmeal cups), which are more like portable oatmeal. Still with me?

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 (85g) old-fashioned whole rolled oats
  • 1 and 1/4 cups (156g) all-purpose flourย (spooned & leveled)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (8 Tbsp; 113g) unsalted butter, melted and slightly cooled
  • 1/2 cup (170g) honey
  • 1 large egg, at room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup (140g) fresh or frozen blueberries (see note if using frozen)


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 425ยฐF (218ยฐC). 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 toย 350ยฐF (177ยฐC). Bake for an additionalย 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 350ยฐF (177ยฐC).) Allow the muffins to cool for 5ย 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:ย 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. Special Tools (affiliate links): Glass Mixing Bowls | Whisk | 12-count Muffin Pan | Muffin Liners | Cooling Rack
  3. Milk: I tested the blueberry muffins with unsweetened almond milk, but any milk, dairy or nondairy, can work. If using frozen berries, see note below.
  4. Oats: I recommend whole oats. Avoid steel cut oats, quick oats, and instant oats. Steel cut oats won’t absorb the milk and quick/instant are too thin and will dissolve in the batter as it cooks.
  5. Flour: For best taste and texture, I recommend all-purpose flour. If you try whole wheat flour, let me know how they turn out!
  6. Oil: You can use canola, vegetable, or melted coconut oil instead of the butter, but the flavor will change. I strongly recommend melted butter.
  7. Sugar: You can use 1/2 cup maple syrup, coconut sugar, or packed light or dark brown sugar instead of honey.
  8. Berries: If using frozen berries, do not thaw and reduce the milk down to 3/4 cup (180ml). Frozen berries give off so much moisture and the muffins taste a little too wet. Reducing the milk helps. No other changes to the recipe ingredients or instructions.
  9. Why the Initial High Temperature?ย 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.
  10. Nutrition: Usingย SparkRecipesย calculator and calculated using unsweetened almond milk these muffinsย come out to 205 calories, 9g fat, 28g carbs, 2g fiber, and 4g protein each.

    I have made these muffins many times now. They are wonderful and just right for my GLP weight loss. I do substitute the butter with Greek yogurt and sugar with half honey and coconut sugar
    Thank you for this receipt

    I have made these muffins many times, and they are always good! I will say that I think they are too sweet with the full 1/2 cup of honey (even when I follow the recipe exactly haha). I’ve made them a few times with the blueberries and some with chocolate chips. This morning I reduced the milk slightly and added a couple of bananas and chocolate chips instead of blueberries. So good!

    I’ve made this recipe about 6 times now, and it’s a great one! My 2 year old loves to help, and the recipe is forgiving if a little of the ingredients end up on the countertop instead of the mixing bowl ๐Ÿ™‚

    I love these as mini muffins and substituting frozen raspberries, and thought I’d share my experience:
    – definitely reduce the milk to 3/4 C when using frozen berries (as listed in the footnotes)
    – Frozen raspberries are a great compliment to this flavor profile; I leave them whole in full size muffins, but break them apart for the minis (the color bleeds a little, but not much)
    – Honey is expensive where I live, I prefer to substitute 2/3 C. brown sugar (as another commenter suggested! I’ve tried 1/2C, but 2/3 is just right)
    – They stick to liners and don’t peel away nicely! Just spray the pan well and they pop right out
    -For MINI muffins, bake at 350F for 15-17 min.

    Excellent! My family and I loved these and my son even took a few to work to share with coworkers!

    This is not sweet enough. The oats are a little chewy. Its just not good.

      Perfect for a cool March morning. Substituted King Arthur bread flour, all I had besides wheat. Substituted flax for egg. Frozen organic blueberries and organic Bob’s Red Mill oats were perfectly blended. Will add a few walnuts next time. Will pass on to friends.

    Iโ€™ve made this recipe a handful of times now, my entire family loves it! When using frozen blueberries itโ€™s really important to measure the amount of berries and reduce the amount of milk. Donโ€™t skip those steps! Thank you for another great recipe!

    Such a delicious recipe! These taste like the blueberry muffins in the bakery section of my supermarket (in a good way) and they’re healthier. I followed every step in detail. I used frozen wild blueberries and raw honey. Perfect grab and go breakfast, I have it along with a protein smoothie. I might try with whole wheat flour instead of all purpose flour next time!

    Love making these muffins. I freeze them and when I need one I set it out on the counter for a little while and pop it in the microwave for 30 seconds. SO yummy.

    Yum! Deliciously buttery and lightly sweet. The texture was perfectโ€”I upped the time at 350 to 20 minutes. Puffed up tops like Iโ€™ve never been able to achieve before! I mixed maple syrup and honey for the sweetener. So good.

    I made these with gluten free king arthur flour substituted 1 for 1. They came out a bit moist but that’s my fault. I saw a little crumble on the toothpicks and hubby said they were good when my gut said another minute. Lol. overall they taste fantastic for zero refined sugar.
