Do not overmix the batter or the muffins may become dense. If using frozen blueberries, add them directly from the freezer without thawing. For lemon blueberry muffins, add the zest of 1 lemon. For a sweeter variation, fold in 1/2 cup white chocolate chips. Sprinkle coarse sugar on top before baking for a bakery-style finish.
