These Sour Cream Blueberry Muffins have a super moist texture and are loaded with fresh, juicy blueberries. Topped with a delicious crumb topping better than any bakery.
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 You'll Love This Recipe
Incredibly Moist: The sour cream makes these muffins extra soft and rich, giving them that bakery-style texture that stays moist for days.

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 Ziploc 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.
