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 the Crumb Topping (Optional): 1/2 cup all-purpose flour, 1/4 cup packed brown sugar, 1/4 teaspoon ground cinnamon, 3 tablespoons cold unsalted butter, cut into small pieces

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 crumb topping first, if using: In a small bowl, mix the flour, brown sugar, and cinnamon. Cut in the cold butter using your fingers or a pastry blender until the mixture resembles coarse crumbs. Set aside in the refrigerator while you make the batter.
  3. In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt. This is your dry mix.
  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 until just combined. Do not overmix; a few lumps are fine. Overmixing develops gluten and makes tough muffins.
  6. Gently fold in the blueberries. If using frozen berries, toss them with 1 teaspoon of flour before adding them to the batter; this helps prevent sinking.
  7. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
  8. If using the crumb topping, sprinkle the chilled mixture evenly over the top of the batter in each cup.
  9. Bake for 5 minutes at 400°F (200°C). Then, reduce the oven 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. Baking at a high initial temperature helps create those tall, bakery-style domes.
  10. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For the moistest texture, use room temperature milk and eggs.
  • To get those beautiful, tall domes, make sure your oven is fully preheated before you start baking.
  • If you want jumbo blueberry muffins, use a large muffin tin and increase the baking time slightly.
  • These muffins freeze well. Cool them completely, then store them in an airtight container in the freezer for up to three months.
