This recipe delivers incredibly moist, fluffy blueberry muffins with tall domes, just like you find at a bakery. It is an easy, one-bowl method perfect for beginners, using fresh or frozen berries for a burst of flavor. Add the optional streusel topping for extra crunch.

Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 3/4 cup granulated sugar
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, melted and slightly cooled
  • 2 large eggs, room temperature
  • 1/2 cup whole milk
  • 1 teaspoon vanilla extract
  • 1 1/2 cups fresh or frozen blueberries (do not thaw if frozen)
  • For Optional Crumb Topping: 1/2 cup all-purpose flour, 1/4 cup packed brown sugar, 1/4 teaspoon ground cinnamon, 2 tablespoons cold unsalted butter (cut into small pieces)

Instructions

  1. Preheat your oven to 400°F (200°C). Line a standard 12-cup muffin tin with paper liners or grease well.
  2. If making the crumb topping, combine the topping ingredients (flour, brown sugar, cinnamon, and cold butter) in a small bowl. Use your fingers or a pastry blender to cut the butter into the dry ingredients until coarse crumbs form. Set aside.
  3. In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt. This is your dry mix. Give yourself a high-five for starting this easy one bowl muffins process!
  4. In a separate medium bowl, whisk together the melted butter, eggs, milk, and vanilla extract until combined.
  5. Pour the wet ingredients into the dry ingredients. Mix gently with a spatula only until just combined. Do not overmix; a few lumps are fine. Overmixing stops you from achieving those fluffy blueberry muffins.
  6. Gently fold in the blueberries. If using frozen berries, do not toss them in flour first; just fold them in carefully to prevent the batter from turning purple.
  7. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
  8. If using the topping, sprinkle the crumb mixture evenly over the top of the batter in each cup.
  9. Bake at 400°F (200°C) for 5 minutes. Then, without opening the oven door, reduce the temperature to 375°F (190°C) and continue baking for another 15 to 18 minutes, or until a toothpick inserted into the center comes out clean. This two-temperature method helps create that tall dome for bakery style blueberry muffins.
  10. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. You did it!

Notes

  • For the juiciest berry bursts, gently toss your fresh or frozen blueberries with 1 teaspoon of flour before folding them into the batter. This helps keep them suspended in the batter.
  • If you want jumbo blueberry muffins, use a large muffin tin and increase the baking time slightly, checking often after 20 minutes at the lower temperature.
  • These classic blueberry treats freeze well. Cool them completely, then store them in an airtight container for up to three months.
