Nothing beats a classic blueberry muffin, we love to make them on the weekends to have with breakfast with my Sausage Tomato Cheese Omelet, or for just an afternoon snack. I usually double the batch and freeze some for a quick breakfast or treat later in the week like my Chocolate Chip Muffins. I guarantee your family or guests will love this sour cream blueberry muffins recipe as much as mine.
Why this recipe works
The sour cream adds a tangy flavor to the muffins, which pairs perfectly with the sweetness of the blueberries. These fluffy muffins are a delicious grab-and-go breakfast or Sunday morning brunch option like my Blueberry Cream Cheese Danish or Lemon Blueberry Scones.
Ingredients for Blueberry Sour Cream Muffins
- Sour cream: Use full-fat sour cream or you can substitute for plain greek yogurt.
- Blueberries: I prefer to use fresh blueberries but frozen can also be used.
- Sugar: Granulated sugar goes in the muffins but you can use brown sugar for the crumb topping if you prefer.
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 together 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 to much can cause dry muffins.
- I like to place a few blueberries on top of each muffin 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 to it.
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 and 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.

So happy you enjoy them, they are a huge fav in our house too!
I have made these several times, and I have no complaints! They always come out tender and flavorful. I have found that the streusel topping makes way too much, so I just pop the rest of it in a baggie in the freezer to use on later muffins. I kind of love having extra streusel topping lying around. 😏
When this happens just pop it in the fridge for a bit then use a fork to make it into crumbles.
I have been cooking for many years and made the recipe exactly as listed however, the crumb topping wasn't crumbly I actually added more flour, but it was still not correct. The muffins themselves were delicious, but I would use a different chopping.
Great recipe. It made many muffins. In fact I made muffin toppers with the extra batter.
So happy you enjoyed it Cheri 🙂
This recipe is awesome. Very easy and oh so good.
Yay Maureen so happy you love them 🙂
Best blueberry muffin recipe ever! When I feel lazy, I just sprinkle cinnamon on top....yum! (Though, crumb topping is best!) Thank you for sharing!
Woohoo Dasha, so happy you liked it 🙂
