The shape of suncakes is round, of varied sizes. They are characterized by Flaky crusts. Most people eat them with Chinese tea, and some people dissolve them in hot water to make a porridge-like dessert.
The first suncakes were made by the Lin family in the She-Ko area of Shengang Township, Taichung County (now part of Taichung City). The Lin family used condensed malt sugar as a filling for cake pastries. Later on, pastry maker Wei Qing-hai modified the cakes to their current form.
Though not originally called "suncakes", they were given the name by the owner of "Sun Booth", one of the most famous pastry shops that sells them. The name was not trademarked, and other pastry shops used the same name for their own suncakes.
