Equipment

  • Mini muffin pan
  • Mini muffin liners
  • Small (1 Tablespoon) cookie scoop (optional but helpful)

Ingredients

  • 2 Tablespoons unsalted butter
  • 1 ⅛ cups all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon baking soda
  • teaspoon salt
  • 2 Tablespoons vegetable oil
  • ¼ cup granulated sugar
  • 2 Tablespoons light brown sugar
  • 1 Tablespoon lemon zest (zest of one lemon)
  • 1 large egg
  • 2 Tablespoons sour cream
  • 3 ounces milk
  • ¾ cup fresh blueberries

Instructions

  • Preheat the oven to 425°F (218°C). Line a mini muffin pan with paper liners and set it aside.
  • Melt the butter in a medium bowl in the microwave. Set the melted butter aside to cool slightly while you move on to the next step.
  • In another medium bowl, add flour, baking powder, baking soda, and salt and whisk to combine. Set aside.
  • To the melted butter add vegetable oil, both sugars, and lemon zest. Whisk to combine.
  • Add egg and whisk to combine.
  • Add sour cream, milk, and vanilla and whisk one more time until the mixture is well blended.
  • Add the flour mixture to the liquid mixture and gently fold the dry ingredients into the wet ingredients just until blended. Do not over mix the batter.
  • Add the blueberries to the muffin batter and fold the berries into the batter just until well distributed.
  • Divide the muffin batter evenly into the prepared muffin pan so that each liner is ¾ full.
  • Bake the muffins at 425°F (218°C) for 4 minutes, then turn down the oven temperature to 350°F (177°C), keeping the muffins in the oven and without opening the oven door. Continue to bake the muffins until the tops are golden and spring back when gently poked, about 10-12 minutes more.
  • Let the muffins cool in the pan on a wire rack for 10 to 15 minutes. Then carefully remove the still-warm muffins from the pan and transfer them to the wire rack to cool completely.

Notes

Storage: Muffins are best on the day they are baked, though leftovers can be stored in an airtight container at room temperature for up to 3 days.
Freezing: Muffins can be frozen, stored in an airtight container, for up to 1 month.
A cookie scoop makes cleanly portioning muffin batter into the pan easy. A small, 1 Tablespoon scoop is perfect for mini muffins.
