Ingredients
- Old-fashioned rolled oats: These add a nice texture to the batter. Don’t skip soaking the oats in the buttermilk.
- Buttermilk: This ingredient provides tanginess and helps achieve a moist crumb. To make a homemade version, add a tablespoon of white vinegar or lemon juice to a liquid measuring cup. Then, fill the cup with milk to the 1-cup line. Stir together and let it sit for at least five minutes before using.
- All-purpose flour: Forms the base for the muffin batter.
- Baking powder and baking soda: Leavening agents for a fluffy texture. Remember to check the expiration date.
- Salt: Enhances flavors and balances the sweetness.
- Light brown sugar: Adds the right amount of sweetness and moisture.
- Egg: Binds the ingredients together.
- Vegetable oil: Adds moisture to the muffins.
- Lemon zest: Adds brightness and complements the blueberries.
- Chia seeds (optional): Adds crunch and a nutritional boost.
- Fresh blueberries: Juicy berries that burst when baked.
How to make blueberry oat muffins
- The first thing we’ll do is preheat the oven to 400℉/200℃. Position the rack in the middle. Grease or paper-line 12 muffin cups.
- Next, soak 1 cup of old-fashioned oats in 1 cup of room-temperature buttermilk. It is important not to skip this step as this will contribute immensely to the soft, tender crumb of these blueberry muffins.
- Meanwhile, measure out the dry ingredients in another bowl. More specifically, 1 cup of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, ½ teaspoon salt, and ½ cup brown sugar (lightly packed). As an option, you can add 1 tablespoon of chia seeds. Whisk together. Set it aside.
- Whisk one egg in the oat mixture along with ¼ cup of vegetable oil and the lemon zest of half a lemon. Make sure to whisk these ingredients together properly.
- Add the wet ingredients to the dry ones, and mix only until combined, using a wooden spoon or rubber spatula.
- Then gently add one heaping cup of blueberries. A few more gentle stirs, and that’s it.
- Portion the batter into a muffin container lined with paper cups. Fill muffin liners ¾ full. Bake for 15-22 minutes or until the top bounces back when lightly touched. You will have the best blueberry muffins with oatmeal.
Tips
- Use room temperature ingredients to ensure the wet ingredients combine smoothly.
- Whisk the dry ingredients together to evenly distribute the leavening agents and prevent large air pockets.
- To avoid soggy muffins, cool them in the tin for just 1-2 minutes before transferring them to a wire rack to cool completely.
FAQ
You can use quick oats in a pinch, but old-fashioned rolled oats are preferred as they have a heartier texture. Quick oats will give a slightly different texture and may absorb the buttermilk differently.
Yes, you can use frozen blueberries. Don’t thaw them before adding them to the batter, or they will bleed too much and turn the batter purple. Toss them in a little flour before adding to the batter to help distribute them evenly.
If you don’t have buttermilk, you can substitute by measuring one tablespoon of lemon juice or white vinegar and placing it in a measuring 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.

Recipe origins
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 and/or 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 they have always been appreciated by family and friends.
Make sure you try out these Date Bran Muffins, a great high-fiber muffin to have for breakfast, and these super moist Banana Muffins, which will intoxicate you with their wonderful aroma while they are baking. 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!

The original recipe calls for melted butter, but as you can see, I substituted with vegetable oil. The ¼ cup of vegetable oil can be replaced with applesauce. The all purpose flour can be replaced with whole wheat flour.

OK my muffin failures are legendary. On the other hand my brother has the knack for making the best muffins ever – light and fluffy, soft and moist, slightly crunchy on the outside bursting with fruit. So with some apprehension and fully prepared to challenge Maria statement that these were the ” easiest and best muffins recipe ever”. But Maria you are absolutely correct and at last I have made delicious edible muffins! I can’t give it 5 stars because my brother Tom’s muffins are still the very best!
Maria
Love this! Thanks so much for sharing Tana!
Emily
So good and tender. I added flax seed meal, chia seeds, and poppy seeds, plus some extra buttermilk to think it out after those additions. Great recipe
Ambika
Hi Maria,
Thank you for sharing this wonderful recipe. This has become my go to blueberry muffin & also the only one requested by my picky tween! Sometimes I follow the recipe strictly; other times I tweak it. Nevertheless they turn out delicious all the time 🙂
Janice R
I make these muffins for friends and coworkers. They are the best muffins anyone has ever tasted! I’ve even made them with gluten-free oat-buckwheat flour for a friend who must have gluten-free foods and this is now her favorite muffin recipe! To fancy them up I sprinkle crystal sugar on the tops before baking 🙂
Maria
I am so thrilled to read this! Thanks so much for sharing that helpful information Janice.
Louise
Loved this muffin. Not overly sweet and fresh tasting. Will be a favourite thanks .
Maria
Thanks so much Louise!
Robin O
I just made these. Very tasty. I might try quick oats or grind up the old fashioned oats next time, to tenderize the results
Mike P
Delicious tender crumb blueberry muffins. The lemon zest elevates them to another level – blueberries and lemons are wonderful together! I used steam refined Nutiva coconut oil in place of the vegetable (seed) oil. I love sharing these muffins with friends. Thank you Maria!
Maria
My pleasure Mike! Thanks so much for taking the time to share!
Maryse

Nicki Domino
These were amazing muffins. I used frozen blueberries. I not only used the zest of half a lemon but added the juice too. Thanks Maria!
Maria
How wonderful! Thanks for sharing Nicki!
Kristen
Love it!. I doubled the recipe and used half whole wheat flour and half unbleached all purpose flour. I also added a pinch of cinnamon and a little lemon juice (in addition to the zest). AMAZING!
Maria
Love this variation Kristen! Thanks so much for sharing!
Coleen Lewis
Can I use the zest of a orange instead of the zest of a lemon
Maria
Yes, that is a perfect substitution! Thanks for stopping by Coleen!
