These homemade blueberry muffins bake up with tall, golden domes and a tender, buttery crumb. The sour cream keeps them rich and moist and lemon zest adds brightness. A crackly cinnamon streusel on top gives them that bakery-style finish without the coffee shop price tag.

Here’s Why This Blueberry Muffin Recipe Works

Sour cream keeps them soft: The fat and acidity make the crumb extra tender with just the right hint of tang.

Bright flavors: Lemon zest wakes up the batter and keeps the flavor from being too heavy.

Bakery-worthy streusel: Brown sugar, butter, and cinnamon bake into a crisp, golden crown.

Versatile blueberries: Works with fresh or frozen berries, so you can bake these any time of year.

Recipe Tips

Start with room temp ingredients: Softened butter and warm eggs cream together smoothly, trapping air for a lighter rise.

Fold gently: Mix just until the flour disappears. Overmixing develops gluten and leads to dense muffins.

Stick with full-fat: Sour cream with full fat gives you the richest flavor and the most tender crumb.

Test early: Begin checking at 24 minutes. Every oven is different, and a few extra minutes can dry them out.

Cool before storing: Let muffins cool completely before sealing them up. This keeps the streusel topping crisp.

Blueberry Streusel Muffins

By Dahn Boquist
Bursting with juicy blueberries and topped with a crumbly streusel topping, these sour cream blueberry muffins are incredibly soft, tender, and fluffy. The addition of sour cream gives them a light, creamy texture and a little bit of tang that compliments the sweet blueberries perfectly.

  • ½ cup brown sugar, 105 grams

Notes

Check your leaveners: Make sure the baking powder and baking soda are fresh, or the muffins won’t rise properly.
Bring ingredients to room temp: Softened butter and room-temperature eggs blend more smoothly and help the muffins rise. (If your eggs are cold, place them in a bowl of warm water for 5 minutes.)
Use full-fat sour cream: It creates the most tender, flavorful crumb. Reduced-fat works, but the texture won’t be as rich.
Adjust sweetness if needed: You can reduce the sugar to ¾ cup without affecting the structure of the muffins.
Fold, don’t stir: Gently fold the dry ingredients into the wet with a spatula. Overmixing develops gluten and makes muffins tough.
Blueberry tip: This batter is thick, so the berries usually stay suspended. Tossing them lightly in flour isn’t necessary, but if you’re using very large berries, it can help keep them from sinking.

    The blueberry strudel that I have ever tasted. I used brown sugar instead of regular sugar in this recipe. Gave my neighbor some of the muffins and she said they were wonderful!
