Taiwanese pineapple cakes have a rich history dating back to the early 19th century. Created in southern Taiwan, these delectable treats combine the sweetness of pineapple with a buttery, crumbly crust. As trade with Japan flourished in the late 19th century, pineapple became a popular fruit exported from Taiwan to Japan, leading to the creation of pineapple cakes as a way to preserve and showcase the fruit's flavor.
