The buttermilk bar is a glazed donut-bar preparation with a denser, cake-like bite and the tang associated with buttermilk batter. Its elongated shape gives more browned surface and glaze than a small round donut, creating a crisp edge around a moist center. The item is explicitly identified in the shop's customer dish listings, though the available evidence does not specify the current price or full ingredient list. This is a vegetarian pastry, with no verified peanut- or shellfish-free kitchen claim.
