Nothing says breakfast better than a warm blueberry muffins with fresh fruit and a cup of coffee. This recipe for Blueberry Muffins is no exception. Made with plump, fresh blueberries, each bite of these muffins is bursting with bright berry flavor. A vanilla lemon quark mixture is folded into the muffin batter giving these a denser, creamier texture and a slight warmth from the vanilla that contrasts wonderfully with the tang of the lemon zest. Sprinkle with powdered sugar and serve.
