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
  • 1 large egg, lightly beaten
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 1 1/2 cups fresh or frozen blueberries (do not thaw if frozen)
  • For Streusel Topping: 1/4 cup all-purpose flour
  • For Streusel Topping: 1/4 cup packed brown sugar
  • For Streusel Topping: 2 tablespoons cold unsalted butter, cut into small pieces
  • For Streusel Topping: 1/4 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 400°F (200°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. Prepare the streusel topping: In a small bowl, combine the flour, brown sugar, cold butter pieces, and cinnamon. Use your fingers or a pastry blender to cut the butter into the dry ingredients until coarse crumbs form. Set aside.
  3. Prepare the dry ingredients: In a large bowl, whisk together the 1 3/4 cups flour, granulated sugar, baking powder, and salt.
  4. Prepare the wet ingredients: In a separate medium bowl, whisk together the melted butter, egg, milk, and vanilla extract until combined.
  5. Combine the mixtures: 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 for a tender crumb.
  6. Fold in the blueberries: Gently fold in the blueberries. If using frozen, do not stir vigorously to prevent the batter from turning purple.
  7. Fill the muffin cups: Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds full.
  8. Add the topping: Sprinkle the prepared streusel topping evenly over the batter in each cup.
  9. Bake: Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. For jumbo muffins, bake for 22-25 minutes.
  10. Cool: Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For the juiciest berries, toss your fresh or frozen blueberries with 1 tablespoon of the measured flour before folding them into the batter. This helps prevent them from sinking to the bottom.
  • To achieve a bakery-style dome, fill the muffin cups completely full, almost to the top edge.
  • Use room temperature milk and egg for better batter incorporation.
