Ingredients

  • 2 cups all-purpose flour
  • 0.8 cups granulated sugar
  • 2 tsp baking powder
  • 0.5 tsp baking soda
  • 0.3 tsp salt
  • 2 large eggs
  • 0.5 cups neutral oil 
  • 0.8 cups sour cream
  • 3 tbsp fresh lemon juice
  • 2 tbsp lemon zest
  • 1 tsp  vanilla extract
  • 1.5 cups fresh or frozen blueberries
  • 1 tsp  all-purpose flour (for coating blueberries)

Instructions

  • Preheat your oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease well with non-stick spray.
  • In a large bowl, whisk together 2 cups all-purpose flour, 0.8 cups granulated sugar, 2 teaspoons baking powder, 0.5 teaspoons baking soda, and 0.3 teaspoons salt until combined.
  • Make a well in the center of the dry ingredients. Add 2 large eggs, 0.5 cups neutral oil (vegetable or canola), 0.8 cups sour cream, 3 tablespoons fresh lemon juice, 2 tablespoons lemon zest (about 2 lemons), and 1 teaspoons vanilla extract. Stir everything together until just combined — do not overmix. A few small lumps are fine.
  •  In a small bowl, toss 1.5 cups fresh or frozen blueberries with 1 teaspoons all-purpose flour (for coating blueberries) until lightly coated. Gently fold the blueberries into the batter.
  • Divide the batter evenly among the 12 muffin cups, filling each about ¾ full. For bakery-style domes, fill to just below the rim.
  • Bake at 425°F for 21 minutes , then (without opening the oven) reduce the temperature to 375°F (190°C) and bake for another 14–16 minutes, until a toothpick inserted in the center comes out clean.
  • Let the muffins cool in the pan for 5 minutes , then transfer to a wire rack. Serve warm or at room temperature.

Notes

-The 425°F → 375°F trick: Starting at high heat creates a burst of steam that pushes the muffin tops up fast — that's your dome. Dropping the temp finishes the bake without burning.
-Frozen blueberries: Use straight from the freezer. Do NOT thaw first.
-Extra lemon flavor: Add a simple lemon glaze (1/2 cup powdered sugar + 1 tbsp lemon juice) drizzled over cooled muffins.
