Method
Step-by-Step
- Heat the oven to 375°F (190°C), then line a 12-cup muffin pan with paper liners or grease it thoroughly.
- Whisk the flour, sugar, baking powder, and salt together in a large bowl. If desired, reserve a tablespoon of this mixture for gently coating the blueberries.
- In a separate bowl, whisk the melted, slightly cooled butter with the eggs, vanilla, and milk until smooth. Stir in the lemon zest if using.
- Pour the wet mixture into the dry ingredients and stir just until no dry flour remains. The batter should be thick and slightly lumpy, not smooth.
- Fold in the blueberries gently, taking care not to crush them. Add frozen blueberries straight from the freezer without thawing.
- Let the batter rest for 10 to 30 minutes, then divide it evenly among the muffin cups, filling them nearly to the top. Sprinkle with coarse sugar if desired.
- Bake for 22 to 28 minutes, until the tops are golden and a toothpick inserted in the center comes out clean or with a few moist crumbs. Cool in the pan for about 5 minutes before transferring the muffins to a rack.
Notes
For taller tops, fill the cups generously and rest the batter before baking. Frozen blueberries may need a few extra minutes in the oven. Store cooled muffins airtight at room temperature for up to 2 days, refrigerate for longer storage, or freeze for up to 3 months.
