Everyone should have a go-to recipe for Blueberry Oat Muffins.
I know a few of you who would tell me that your go-to muffins are at Costco.
Well, I would definitely encourage you to go to Costco to purchase their wonderful blueberries so that you can make your own oatmeal blueberry muffins.
While you are there, I would also encourage you to pick up some dates and a bunch of bananas. Here’s why…
Once you realize how wonderful these Blueberry Oat Muffins are, I guarantee you are going to be equally impressed with these super moist Banana Muffins and these amazing Date Bran Muffins. Scout’s honor!
So, go to Costco, and get your fresh fruits… and then we will combine some plump, juicy blueberries, with oats! You won’t believe how truly amazing these buttermilk blueberry muffins are!
As you probably know, muffins are a type of quick bread that usually comes together in no time at all. The only requirements are two bowls and a mixing spoon.
Let me show you how in just half an hour, you could be enjoying the best blueberry oatmeal muffins ever!
HOW TO MAKE BLUEBERRY OAT MUFFINS:
The first thing we are going to do is soak the oatmeal in buttermilk. It is important not to skip this step as this will contribute immensely to the soft, tender crumb of these blueberry muffins.
In the meanwhile, measure out the dry ingredients in another bowl and whisk them together. Set it aside.
Whisk an egg in the oat mixture along with the oil. Make sure to properly whisk these ingredients together.
Add this liquid mixture to the flour mixture and with a wooden spoon, mix only until combined. Then gently add in the blueberries. A few more gentle stirs and that’s it.
Portion the batter in a muffin container that has been lined with paper cups and bake in a preheated oven. In about twenty minutes, you will have the best ever blueberry muffins with oatmeal.
How to make buttermilk out of regular milk?
If you do not have buttermilk, you can still make these wonderful muffins. Here’s how: measure one tablespoon of lemon juice or white vinegar and place in a measurement cup. Pour in enough milk to reach the 1 cup mark. Stir and let stand for at least 5 minutes, so that the acidity can start curdling the milk. I love using buttermilk in pancakes and in biscuits. The end product is always fluffy and I love the “tanginess” of flavor it provides.
Recipe update: Over the years, so many of you have tried this easy muffin recipe and have provided some wonderful comments.

ORIGINS OF THE RECIPE FOR BLUEBERRY OAT MUFFINS:
It seems like I’ve been collecting recipes all my life. As a teenager, I used to check out cookbooks from the public library and write out the recipes that I liked. Can you imagine that? Did anyone else do that or was it only me? Although it has been over forty years, I still remember sitting in the kitchen and copying recipes…
Needless to say, this obsession with recipes has resulted in quite an assortment of cookbooks over the years. This library of mine also includes collections of recipes that I obtained by mailing in the UPC code and/or a money order in exchange for the booklets.
I’ve adapted this recipe for buttermilk muffins from the “Robin Hood Recipe Collection”. I’ve been making them for decades and it has always been appreciated by family and friends.
Make sure you try out these Date Bran Muffins, which are a great high fiber muffin to have for breakfast and these super moist Banana Muffins which will intoxicate you with the wonderful aroma while they are baking. Both of these muffins are from the same recipe collection so you know they are good 🙂
From one muffin lover to another, I hope these muffins will become a tradition in your home, too!
THANKS SO MUCH for following and being part of the She loves biscotti community where you will find Simple & Tasty Family-Friendly Recipes with an Italian Twist.

The original recipe calls for melted butter, but as you can see, I substituted with vegetable oil. The 1/4 cup of vegetable oil can be replaced with applesauce. The all purpose flour can be replaced with whole wheat flour.

Excellent, easy and moist muffins. Great recipe. A keeper.

Janet Miller says
These are quite good with a few tweaks. I increased salt to 1 teaspoon and added 1 teaspoon of vanilla.
Maria says
That’s the wonderful thing about homemade recipes, everyone can tweak to their liking… Thanks so much for taking the time to comment Janet, appreciate it!
Jenny says
Made these for the first time this morning, they were EXCELLENT! They had the perfect texture and I loved that they weren’t overly sweet. My picky 7 year old ate 3 and he wanted to have another but I stopped him. Thank you for the great recipe! I will definitely be making this recipes over and over again.
Maria says
How wonderful Jenny! I am thrilled to hear this. Thanks so much for taking the time to comment, truly appreciate it!
Cindy says
These are easy and yummy, as advertised.
Maria says
Thanks Cindy. I’m so glad to hear you enjoyed these blueberry muffins. Thanks so much for taking the time to share, appreciate it.
Jenn says
These are quick easy and delicious! My normal go to blueberry muffin recipe is an adaptation from Williams Sonoma, but they are more cupcake like – they are sweeter and have a crumb topping. I wanted to try something with some oats. These are great! Hearty, but light, not to sweet. Definitely a muffin not a cupcake. Perfect! (Also I was out of light brown sugar sinuses very slightly less dark drown sugar – a little heavier flavor but still delicious!) thanks for this great recipe! It might become my new go to!
Maria says
How wonderful Jenn! I am very happy to hear you are enjoying these blueberry muffins. Appreciate you taking the time to comment.
Stephanie Shambo says
Absolutely delicious!! My son is currently on his second one. Thank you for the recipe! We’re trying the banana muffins next!
Maria says
Fantastic Stephanie! Wonderful to hear you guys are enjoying these blueberry muffins! Oh, you are just going to love those!!! Thanks so much for taking the time to comment, appreciate it!
Dawn @ The Kitchen and a Latte says
I absolutely love everything blueberries 🙂 I have been picking them here at the local farm and will probably be getting a blueberry bush for next year.
Blueberry muffins are my favorite muffin (in case my love of blueberries didn’t give that away already.) Going to be making these for sure and I think I will use the melted butter – it is one of my go to fats for all besides olive oil and coconut oil.
Maria says
I absolutely agree Dawn! Such a great berry to snack on or to bake with. Thanks so much for stopping by, appreciate it!
Bev says
THIS is my new go-to muffin recipe for Airbnb guests. I bake, freeze, and thaw as needed throughout the week. Although delightfully moist, they still hold together and silicon liners peel right off. Thanks, Maria, for helping me get rave reviews for the delicious ¨breakfast” I serve!
Maria says
Love this Bev!!! Congrats! I’m just sharing my love for muffins. Thanks for taking the time to comment, appreciate it.
Lindsay says
I should have sent a rating ages ago! This is my favorite muffin recipe. I have made it almost weekly for the past year! I have varied it with half oil/half applesauce, half whole wheat/half all-purpose flour. They’ve all turned out great! I am not much of a cook or baker, but these muffins make me look like I am! Thanks for a terrific recipe, Maria!
Maria says
Thanks so much Lindsay! I am thrilled to read this. Appreciate you taking the time to share your experience with these oat muffins.
Michelle Mulberry says
I substituted almond flour for all purpose flour and used coconut oil instead of vegetable oil. The muffins didn’t rise and still seemed super wet despite being cooked through. Baked at 400 for 20 min. The taste was definitely there, but wondering if anyone else has commented the same using the same substitutions. If so, what can I do to correct this?
Maria says
Sorry to hear your substitutions did not work Michelle. My guess is that the coconut oil is not the issue. You probably have to experiment a little more with the almond flour. I have read that Chia seeds or ground flax seeds will help absorb the moisture. Hopefully someone has had success using almond flour with this recipe and responds. Thanks for stopping by.
Bev says
Almond flour, much thirstier than wheat flour, doesn work as a 1:1 substitution. You might google for a good ratio. I want to experiment with a homemade gluten-free baking mix like Niliś Baking Mix, but, again, it wont be a 1:1 ratiod, but for now–I dont want to mess with perfection!
Lauren Seeley says
I just made these with 1/2 almond flour and 1/2 all purpose flour (I think that’s what it was thought I’m not quite sure as it was in a jar that I failed to label. But that’s okay since we have no allergies), and they came out excellent!
For oil, I use grape seed oil. Another healthy alternative to olive oil and coconut oil and butter.
Moist and fluffy!
I’ve been using this recipe for over a year, and love it!
Lauren
Maria says
Thanks Lauren. I am happy to hear you are enjoying these blueberry muffins. Love your variations. Appreciate you taking the time to comment.
Ella M. says
I love a lemon-combo in just about any baked goodie, so when I made these, I used the zest of a full lemon and also subbed the vegetable oil with coconut oil. With a light sprinkle of coarse turbinado sugar, these came out of my oven picture perfect! The flavor is simply delightful and I LOVE that they are not an extraordinarily sweet muffin, making them perfect for on the go breakfast. The paper liners come off easily without sticking, which is also very nice! I will definitely be making these again and I may experiment with other combinations including raspberries, strawberries, and zests of orange and lime! Thank you for this awesome recipe!!!
Maria says
My pleasure Ella! Lemon lovers unite!!! Thanks so much for taking the time to share your experience with this recipe, truly appreciate it.
Patty says
Two thumbs up! Again as others, used coconut oil, used thawed patted dry and floured berries, added a few drops of lemon extract and sprinkled turbinado sugar on top b4 baking. They are moist and bursting with berry flavor! Yum!
Maria says
Fantastic Patty! Love the variation!!! Thanks so much for taking the time to share, appreciate it.
Christine says
Wow these were amazing. So soft and fluffy. They did end up a little salty, I’d halve or quarter the amount of salt next time.
Maria says
Thanks so much for taking the time to comment, appreciate it Christine.
Maria says
Great! Thanks so much for taking the time to comment. Appreciate it.
Carol Delserro says
I made both the banana muffins with the chocolate chips and walnuts and the blueberry lemon muffins. They were both moist and delicious and my family loved them. Thanks so much for 2 great recipes. I can’t wait to try other ones you have.
Maria says
Thanks Carol. There is nothing like a warm homemade muffin! Thanks so much for taking the time to comment, appreciate it!
Ali says
These came out amazing! Just had two of them right out of the oven! The recipe was on the spot, and unlike another commenter, I found sweetness to be just perfect, and I don’t even like things very sweet. Maybe they used compact brown sugar rather than the recommended light pack?
Oh, it’s also worth mentioning that I used melted coconut oil, added a few drops of vanilla extract while beating the egg, and rubbed brown sugar with lemon zest before mixing, to get the natural oils out and enhance the lemon flavor–best homemade blueberry muffins you can get your hands on!
Thanks so much Maria for sharing!!! This is a keeper and I’m sure I’ll be making these bad boys over and over again!
Maria says
Amazing Ali! Love your variation with the coconut oil. I am so thrilled you enjoyed these blueberry muffins! Thanks for taking the time to comment, appreciate it ♥
Carol says
Delicious muffins, I added 1 Tbsp of chia seeds ( heart healthy Omega 3) to the oatmeal mixture as well as 1/2 cup flaked coconut and 1/2 cup semi-sweet chocolate chunks. These are our new favourite muffins💕
Carol says
Also, I should add I substituted 1 cup of three berry mix from Costco rather than the blueberries. Was trying to recreate a bakery muffin I had recently and these come pretty close. Will try 1/2 wheat flour and 1/2 all purpose flour next time 💕
Maria says
Love it! I still have not tried the three berry mix from Costco… on my list… I have tried replacing 1/2 of the AP flour with whole wheat and the muffins turn out good. Thanks again Carol ♥
Maria says
That’s wonderful Carol! I’m so happy to hear this. I love the add-ins to this blueberry muffins. Thanks so much for taking the time to share, appreciate it ♥
Mary says
I literally make these every weekend and pack 2 in my husband’s lunch each day during the week! They are fool-proof and absolutely delicious! Thanks!
Maria says
Thanks so much for taking the time to share Mary! I’m so glad you are enjoying this blueberry muffin recipe. I agree, this recipe is a keeper 🙂
Mary says
Hi! I have made these several times and LOVE them. I would like to try them again today and substitute unsweetened applesauce for the butter/oil. Have you tried that? I know it will change the texture, but am wondering if they will bake up okay….
Maria says
Hi Mary, I have not tried to replace the vegetable oil with applesauce for this blueberry muffin recipe but I think it should provide you with a good muffin. If you do try it, I would love to hear about your results. Thanks so much for taking the time to comment, truly appreciate it 🙂
Buzz Bee says
Just made these today and topped with some nuts. ( I also added bran in the oatmeal soak step ) Loved them! not too sweet . This is muffins muffin!
Maria says
How wonderful Buzz Bee! I am absolutely thrilled to hear this. Your variation sounds delicious. Thanks so much for taking the time to comment, truly appreciate it 🙂
Megan says
These were amazing! I substitutes the flour for whole wheat pastry flour. I also baked mine in the top third of my oven at 400 degrees and the rose and didn’t fall flat after coming out of the oven. Been reading more on how to get muffins to rise and it seems like a higher baking temp and position in the oven makes a world of difference. Granted Im sure it greatly depends on where you live as well. To the point this recipe is in my go To now! Perfect New Year Breakfast (went nicely with a mimosas too!)
Maria says
Happy New Year Megan! I am thrilled to hear about your experience with these Blueberry Muffins… thanks so much for sharing! I must try your variation, sounds absolutely delicious. Great comment! Thanks for stopping by 🙂
Cindy says
Hello – I’m anxious to make these and hate going to the grocery store, lol – can I use my frozen blueberries? Thanks!
Maria says
Yes, no need to go to the grocery store. No need to thaw. Be sure to roll the frozen blueberries in a little bit of flour to prevent the whole muffin batter from turning blue. Great comment Cindy! Thanks for stopping by.
