Bakery-Style Blueberry Muffins with Crumble Topping

08/31/2025 | Bonia Bakery |

There’s nothing quite like a bakery-style muffin—the kind with golden, domed tops and a buttery crumble that practically begs you to pull it apart piece by piece. For the longest time, I thought muffins like that were something you could only get from a coffee shop or bakery case. But once I started baking at home, I realized that with just a few tricks, you can recreate that same dreamy muffin texture in your own kitchen.

These blueberry muffins are everything I love in a classic muffin: soft, moist, and bursting with blueberries in every single bite. No dry, crumbly centers here—I made a promise to myself that my muffins would never disappoint like that. The secret? A combination of buttermilk and Greek yogurt, which keeps the crumb tender and rich without feeling heavy.

And of course, we can’t forget the topping. The buttery streusel adds a crunchy-sweet layer that makes these muffins feel bakery-worthy every single time. They’re simple enough for a weekday breakfast but special enough to bake on a weekend morning when you want something cozy and homemade to enjoy with your coffee.

Ingredients

Muffins (Makes 8–10)

  • 6 tbsp unsalted butter, melted
  • ¾ cup granulated sugar
  • 1 large egg, room temperature
  • ¾ tsp vanilla extract
  • 4 tbsp Greek yogurt
  • 4 tbsp buttermilk
  • 2 ¼ tsp baking powder
  • ¼ tsp salt
  • 1 ½ cups + 1 tbsp all-purpose flour (extra tablespoon for tossing blueberries)
  • 1 ⅓ cups blueberries (fresh or frozen)

Buttery Streusel Topping

  • 2 tbsp unsalted butter, melted
  • 2 ½ tbsp granulated sugar
  • ⅓ cup all-purpose flour

Directions

  1. Preheat oven to 375°F (190°C). Line a muffin tin with 8–10 liners.
  2. In a large bowl, whisk together the melted butter and sugar until smooth. Add the egg and vanilla, mixing well.
  3. Stir in the Greek yogurt and buttermilk until fully combined.
  4. In another bowl, whisk together the flour, baking powder, and salt. Add the dry ingredients to the wet and stir gently until just combined—do not overmix.
  5. Toss the blueberries with 1 tablespoon of flour (this helps prevent sinking), then fold them gently into the batter.
  6. Divide the batter evenly between muffin cups, filling each about ¾ full.
  7. Make the streusel topping: mix together the melted butter, sugar, and flour until crumbly. Sprinkle generously over each muffin.
  8. Bake for 18–22 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.
  9. Allow muffins to cool for 10 minutes in the pan before transferring to a wire rack.
