Ingredients
Method
- Preheat oven to 400°F and line a 12-cup muffin tin with paper liners or grease well. Toss blueberries with the tablespoon of flour - this prevents them from sinking to the bottom during baking.
- Whisk together flour, sugar, baking powder, and salt in a large bowl. Create a well in the center - this classic technique ensures even mixing without overworking the batter.
- In a separate bowl, whisk melted butter, egg, milk, and vanilla until smooth. The butter should be warm but not hot enough to scramble the egg.
- Pour wet ingredients into the flour well and gently fold until just combined. The batter should look slightly lumpy - overmixing creates tough, dense muffins. Fold in the flour-coated blueberries with minimal stirring.
- Divide batter evenly among muffin cups, filling each about 2/3 full. Bake for 20-25 minutes until tops are golden and a toothpick inserted in center comes out with just a few moist crumbs. Cool in pan for 5 minutes before transferring to a wire rack.
Notes
Coat blueberries with flour to prevent sinking. Don't overmix the batter - lumpy is perfect for tender muffins. Mix dry ingredients the night before for easier morning assembly. Store at room temperature for up to 3 days or freeze for up to 3 months. Can substitute blueberries with raspberries, strawberries, or chocolate chips.
