Known simply as tarta de queso or gazta tarta in its native Basque, this simple yet incredibly creamy cheesecake variation is a decades-old local specialty of the La Viña Bar in San Sebastián. The recipe is a simple combination of classic cheesecake ingredients such as sugar, heavy cream, eggs, and cream cheese, but unlike its more popular counterparts, this Basque version does not have any crust.

Instead, it is baked on a high temperature which leaves the outside firm, darker, and somewhat burnt, while the center remains gooey. Basque cheesecake is immensely popular, and while La Viña remains its place of origin, different variations are nowadays found in several patisseries around the world.
