Lemon Blueberry Oatmeal Muffins are a sweet and tangy, and a delicious option for breakfast or a snack. This is the best ever oatmeal muffin recipe!
There are two types of muffins in this world. Slightly healthy muffins that are made with ingredients like whole wheat flour and/or oats. And super sweet, pretty much only for dessert muffins.
These muffins are a combination of both, which is why I love them SO much! They’re made with healthier ingredients like whole wheat flour and old-fashioned rolled oats.
Muffins are my favorite grab on the go breakfast or snack. They can be eaten quickly on the way to your car (if you’re like me and have to walk a block to your car) or on your way to work.
They stay fresh for a good 4-5 days, so you can make them ahead of time and enjoy them all week! Careful though, they’re so addicting it’s hard to just have one. 😉
These muffins bake for less than 30 minutes and require minimal effort. Most of the ingredients are pantry staples, so you can make these lemon blueberry muffins just about any time!

These muffins are soft, moist, and have a lovely bright and tangy flavor from the lemons and the blueberries. They’re also sweet but not overly sweet like some muffins can be.
I drizzled them with a sweet and tangy Lemon Blueberry Glaze because it’s so yummy (duh) but also really pretty because the blueberries dye it pink! Add this glaze to your basic muffin recipe and your muffins will instantly become a showstopper.
What Makes These Lemon Blueberry Muffins So Special?
There are a few extra special things going on in this muffin recipe that really make it over the top.
- Lemons and blueberries were just meant to be together. The combination is perfect for any time of year and the lemon adds a wonderfully bright flavor to the muffins.
- These muffins don’t have lots of sugar in them, so the Lemon Blueberry Glaze gives them a touch of added sweetness and makes them completely irresistible. You can leave it off if you prefer them to be less sweet.
- They are so easy to make! Lemon Blueberry Muffins look and sound like something fancy from a bakery, but even better because you get to eat them right out of your oven while they’re still warm.
How To Keep Blueberries From Sinking In The Batter
Blueberry muffins always look (and taste) their best when there are blueberries throughout the muffin. But sometimes the blueberries might move around in the muffin tin.
To make sure you’ve got blueberries throughout the muffin (for ultimate flavor and aesthetic) add a few blueberries to the top of the muffin batter after you’ve filled the muffin tins.
Ingredients For Lemon Blueberry Muffins
Fresh blueberries and lemons are the star of this recipe. We’ve also got whole wheat flour, butter, brown sugar, and a few other pantry staples. The lemon zest goes into the muffins, while the lemon juice goes into the glaze, so no part of the lemon goes to waste!
If fresh blueberries aren’t in season for you, you can use frozen blueberries, just make sure they are thawed for the glaze!
The Lemon Blueberry Glaze is so easy to make. Lemon juice, blueberries, powdered sugar, and buttermilk are combined to make a sweet but tangy glaze for the muffins.
How To Make Lemon Blueberry Muffins
This healthy oatmeal muffin recipe is about to become your new facorite, and I know I’m a little biased but I promise these are soooo good!
- Start by preheating your oven to 375 F. Then line a muffin pan with muffin wrappers.
- In a large bowl, combine the oats and the buttermilk and let them soften while you prep the other ingredients.
- Sift in the the flour, baking powder, baking soda, and salt in another mixing bowl.
- When the oats have softened, add the melted butter, brown sugar, egg, lemon juice and zest, then stir until combined.
- Finish the batter by combining the dry ingredients and the oat mixture, then fold in the blueberries.
- Evenly divide the batter into a muffin tin. Bake for 15-20 minutes or until a toothpick comes out clean.
- When the muffins are finished baking, place the muffin pan on a wire rack to cool, then drizzle each muffin with the Lemon Blueberry Glaze.
How To Make Lemon Blueberry Glaze
The glaze is totally optional but also 100% necessary because it’s so yummy! It’s so simple to make, there’s really no excuse not to!
- Add the blueberries, lemon juice, vanilla extract, and and buttermilk to a food processor or blender and mix on high until completely combined. Then transfer the mixture to a small mixing bowl using a strainer to catch any blueberry remains from the skin.
- Whisk in the powdered sugar until completely combined. You can add more sugar to make the glaze thicker or more buttermilk to thin it out.
If you don’t have a food processor or a blender, you can try muddling the blueberries with a mortar and pestle but you’ll have to really mash them well to release all the juices. I don’t really recommend muddling the blueberries, so you could leave them out and just make a sweet lemon glaze instead.
To make the glaze smooth, I recommend using a fine mesh strainer. If you don’t have one to catch the blueberry remains from the skin, that’s ok, it just makes the glaze a little chunky.
How Do I know If My Muffins Are Done?
A toothpick inserted into the center of the muffin can tell you if they are finished. When the center comes out clean, you’ll know that the muffins are ready to be removed from the oven.
You can also use the touch method. Just touch the top of the muffin lightly with your finger to see if they spring back.

Thank you Julia!
Yummy! I was looking for a lemon blueberry oatmeal recipe and came upon this one. I didn’t have whole wheat flour so I used regular flour. These were delicious and full blueberries with lemony yum! My muffin didn’t crown and came out flat (I may have over-mixed it) but the texture was airy and moist. I feel it does not really need the glaze — but the glaze is tasty! Looking forward to trying other recipes by the author. Thank you!
