Taiwanese Sun Cake Recipe (Tai Yang Bing)

Taiwanese Sun Cake Recipe (Tai Yang Bing)

Sun cake, also known as tai yang bing, is a famous Taiwanese dessert. Belonging to the beautiful city of Taichung, Taiwan, sun cake is made of condensed malt sugar (also known as maltose). The dish looks a little like the sun, thus the reason for its name.

These pastries are round in shape and are available in various sizes. What distinguishes it from normal pastries is its crispy crust. Considered as one of Taichung’s breakfast favourites, people usually enjoy sun cake with Chinese tea or dip it in warm almond milk. People also make sweet porridge out of it by dissolving it in hot water.

Sun cake is a specialty of the city of Taichung. It’s often sold in beautiful gift boxes as a memento for people visiting the place.

History & Cultural Significance

Sun cake filling

Residing in the She-ko region of Taichung County (now a part of the Taichung city), the Lin family made the first sun cakes. For the filling of the dish, the Lin family used malt sugar in a condensed form. Chef Wei Qing-hai later modified the pastry to its present form.

The dish wasn’t called “sun cake” since the beginning. It was much later that the term was used for the cake after a well-known Taiwanese bakery named ‘Sun Booth’ started to sell it by this name. Now, because the term wasn’t brand marked, the other pastry sellers started to use the same title for their own suncakes.
