Instructions
- Preheat oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease thoroughly. In a medium bowl, whisk together the 2 cups flour, baking powder, baking soda, and salt. Set aside. In a separate small bowl, toss the blueberries with 2 tablespoons of flour to coat evenly.
- In a large mixing bowl, beat the softened butter and sugar together until light and fluffy, about 2-3 minutes.
- Beat in the eggs one at a time, followed by the vanilla extract. Scrape down the sides of the bowl as needed.
- Add the flour mixture and sour cream alternately to the butter mixture, beginning and ending with the flour. Mix until just combined - do not overmix.
- Gently fold the flour-coated blueberries into the batter using a spatula. Be careful not to crush the berries or overmix the batter.
- Divide the batter evenly among the 12 muffin cups, filling them almost to the top. Sprinkle with coarse sugar if desired. Bake at 425°F for 5 minutes, then reduce temperature to 375°F (190°C) and bake for additional 15-18 minutes, or until toothpick comes out clean.
- Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
Notes
Use room temperature ingredients for best results. Don't overmix the batter - mix until just combined. Coating blueberries in flour prevents sinking. Start at high temperature (425°F) for 5 minutes then reduce to 375°F for perfect domes.
