These Sour Cream Blueberry Muffins are super moist texture and are loaded with fresh juicy blueberries. Topped with a delicious crumb topping better than any bakery.

I usually double the batch and freeze some for a quick breakfast or treat later in the week like my Chocolate Chip Muffins.

How to Make Blueberry Muffins

- Step 1: In a small bowl, add the crumb topping ingredients and mix until combined, and set aside.
- Step 2: In a large mixing bowl, add the dry ingredients and whisk together.

- Step 3: In another medium bowl, mix the wet ingredients.
- Step 4: Whisk the wet mixture into the dry and mix just until combined.

- Step 5: In a small bowl, add the blueberries and toss with some flour until coated.
- Step 6: Fold the fresh berries into the muffin batter just until combined.

- Step 7: Divide batter into the muffin tin lined with paper liners.
- Step 8: Add the crumb mixture on top of the muffins and place a few extra blueberries on top if you want, and bake!

Recipe tips
- Measure your flour correctly by scooping it into the cup and leveling it off with a knife.
- Do not over-mix the batter; mix until everything is combined. Mixing too much can cause dry muffins.
- I like to place a few blueberries on top of each muffin, and then crumble it allows for a pretty finished muffin top.
- Fill the muffin cups about 3/4 of the way full to give them those delicious muffin tops.
- I like to use an ice cream scoop to fill the muffin cups. But you can also use a spoon to fill them about 3/4 full.

Recipe Faq's
Yes, you can, and no need to thaw, but still toss the frozen berries with a little bit of flour. Frozen blueberries can bleed into the batter from the extra juices, causing the batter to have a purple hue.
I always recommend it! Coating the blueberries in a tablespoon of flour keeps them from sinking to the bottom of the muffin liners during the baking process.
Let cool completely, and place the blueberry sour cream muffins in an airtight container and store them at room temperature for 2-3 days. To Freeze Wrap the homemade muffins in a piece of plastic wrap, place them in a large ziplock freezer bag and freeze for up to 3 months.
Thaw in the refrigerator overnight and reheat in the microwave for 15-30 seconds.
Yes, you can make mini blueberry sour cream muffins they will bake much faster, for 12-15 minutes or until a toothpick comes out clean.

these are sooooo good, super impressed with how they turned out
Haha, that's fantastic Michelle!
Made these this morning! These were super. Husband wants to hide them from dear daughter! Haha!
perfect texture muffin. I made some changes, I doubled the recipe, used 1/2 vanilla yogurt sub for the sour cream, due to this, I reduced the sugar in the recipe by 1/4 cup I also used 1/2 whole wheat flour and I used a bag of frozen wild blueberries didnt coat them in flour because I prefer smaller scattered blueberries. very good. I will freeze some for later.
Have you ever made this recipe as a loaf/breakfast bread? I made the muffins and they were delicious. I used butter instead of vegetable oil. Highly suggest that change!
O. M. G. These are the best, moistest muffins I have ever eaten, let alone made. I love that it makes more than a dozen because 12 is simply not enough!
Yay Charlotte! So happy to hear that š
Thank you for posting the recipe for these yummy muffins! I've been baking the same recipe for over thirty years now and I was like, "I wonder if there's something more delicious?" These are. I didn't gum around and make changes to a perfectly grand recipe and cooked two different size pans on 400 until they were done. YUMMMM! I appreciate your time!
Yay Heather! So happy you loved them š
I can finally stop searching for the perfect blueberry muffin recipe! I usually have to add more blueberries or streusel topping, but not with these! And the sour cream is a perfect addition. These are delicious! Thank you!!!
