Ingredients

  • 2 cups all-purpose flour, plus 1 tablespoon
  • ½ teaspoon salt
  • 2 teaspoons baking powder
  • 2 eggs
  • ½ cup salted butter, melted and cooled
  • ¾ cup granulated sugar
  • 1 teaspoon vanilla extract
  • ½ cup buttermilk
  • 1 cup sour cream
  • 1 cup fresh blueberries, rinsed and dried
  • 2 tablespoons light brown sugar

Instructions

  • Preheat the oven to 425°F. Line a 12-cup muffin pan with cupcake liners or spray with non-stick cooking spray.
  • Sift together the flour, salt, and baking powder in a small bowl and set aside.
  • In a large mixing bowl, beat or whisk together the eggs, melted butter, sugar, vanilla extract, buttermilk, and sour cream.
  • Dump the dry ingredients into the butter and sour cream mixture and stir gently, just until combined. Do not overmix.
  • Toss 1 cup of blueberries with the remaining tablespoon of flour and fold into the muffin batter.
  • Divide the batter between the 12 muffin cups in the prepared pan, filling each cup about ¾ of the way full.
  • Sprinkle brown sugar over the top of the muffins.
  • Bake for 6 to 7 minutes at 425°F and then turn the oven down to 375°F and continue baking an additional 10 to 12 minutes until a toothpick inserted in the center of the muffins comes out clean and the tops are golden brown.
  • Cool muffins in pan for 5 minutes. Remove muffins to a cooling rack to finish cooling.

Notes

  • You can use unsweetened frozen blueberries instead of fresh blueberries in equal amounts. Don’t let them thaw; just put them directly from the freezer into your batter.
  • Do not over-stir the batter. The muffins will be too dense and tough.
  • Coating the blueberries in flour will help keep them suspended in the muffins while baking, so you will have a nice distribution throughout.
  • Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your muffins at the lower end of the recommended baking time. 
  • Do not leave the muffins to cool in the muffin tin any longer than 5 minutes. The heat from the pan will overcook them.
