They are usually topped with a sprinkle of cinnamon or powdered sugar. These treats are named after the famous Pío Nono, a pope known for his love of sweets. Piononos are popular at celebrations and gatherings, enjoyed for their delightful flavors and appealing presentation. They reflect the rich culinary heritage of Puerto Rican cuisine.
