Rosquillas de Santa Clara are Spanish doughnuts traditionally prepared for the feast of San Isidor. They consist of a round-shaped, anise-flavored dough that is generously covered in a powdered sugar glaze. The dough is wrapped into a circle, leaving a hole in the middle.

Rosquillas de Santa Clara are baked in the oven, and when chilled, they are coated in a thick glaze made with sugar and whipped egg whites. These doughnuts are traditionally associated with Madrid, and they are a staple on the feast of San Isidor, the city's patron saint.
