Make cake mix blueberry muffins with white cake mix, fresh blueberries, and a lemon glaze, perfect for breakfast, dessert, or a snack. Cake mix muffins use boxed cake mix instead of muffin mix for a sweet, moist muffin that's closer to cake than bread. Fresh berries and lemon zest are added to the muffin batter for a fresh, flavorful muffin. The muffins are topped with a sprinkle of turbinado sugar and a drizzle of powdered sugar glaze.
