Blueberry-Lemon Crumb Muffins
Blueberries and lemon are a natural pairing in these light and airy muffins with a delicate brown sugar crumble. If you like an extra blast of lemon flavor, use lemon extract rather than vanilla. These muffins are best with fresh blueberries, but you can substitute with frozen. Don't thaw them before you stir them into the batter.
