Prep the pan and oven. Heat the oven to 425°F (220°C).
Line a 12-cup muffin tin with liners or grease well.
Whisk dry ingredients. In a large bowl, whisk flour, baking powder, baking soda, and salt until well combined.
Mix the wet ingredients. In a separate bowl or large measuring cup, whisk sugar, brown sugar, eggs, yogurt, oil, milk, vanilla, and lemon zest until smooth.
Combine wet and dry. Pour the wet mixture into the dry. Stir gently with a spatula until just combined. The batter should be thick and slightly lumpy. Do not overmix.
Fold in blueberries. Toss the blueberries with 1 tablespoon flour, then fold them into the batter using a few gentle strokes.
Fill the cups. Divide batter evenly among the muffin cups, filling them almost to the top for tall domes.
Sprinkle with coarse sugar if using.
Bake high, then lower. Bake at 425°F (220°C) for 5 minutes to jump-start the rise. Without opening the oven, reduce heat to 350°F (175°C) and bake 12–15 more minutes, until a toothpick comes out clean or with a few moist crumbs.
Cool and enjoy. Let muffins cool in the pan for 5 minutes, then transfer to a rack. Eat warm or at room temperature.
