Christy's buttermilk donut is a glazed bar with a crunchy outer surface and a moist, softer center. The buttermilk flavor gives the pastry a noticeable tang beneath the sweetness of the glaze, distinguishing it from a standard raised donut. Customer descriptions emphasize the contrast between the crisp exterior and tender middle. It is a vegetarian pastry, but the available evidence does not establish a peanut-free or shellfish-free preparation area.
