Instructions
- Preheat your oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease thoroughly. In a small bowl, toss the blueberries with 1 tablespoon of flour to prevent sinking during baking.
- In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and sugar. Make sure everything is evenly distributed for consistent texture.
- In a separate bowl, whisk together the melted butter, eggs, sour cream, milk, and vanilla extract until smooth and well combined.
- Create a well in the center of your dry ingredients and pour in the wet mixture. Gently fold together until just combined - do not overmix! A few lumps are perfectly fine.
- Gently fold in the flour-coated blueberries, being careful not to overmix. The batter will be thick, which is exactly what you want for those tall bakery-style domes.
- Divide the batter evenly among the 12 muffin cups, filling them almost to the top. Bake for 5 minutes at 425°F, then reduce the temperature to 375°F (190°C) and bake for another 15-18 minutes, or until a toothpick inserted comes out clean.
- Let the muffins cool in the pan for 5 minutes before transferring to a wire rack to cool completely. This resting period helps set the structure.
Notes
Use room temperature ingredients for even mixing. Don't overmix the batter - a few lumps are okay. The high initial oven temperature creates the signature bakery dome. Coating blueberries in flour prevents sinking.
