Egg hong cake is a small folded griddle cake, one of Chengdu's best-loved street snacks. A batter of egg, leavened flour and a little brown sugar is ladled into a shallow copper pan over low heat; as it sets it rises into a soft little disc, browned and faintly crisp underneath, spongy and tender on top. While still in the pan it is filled and folded into a half-moon — sweet with sesame-sugar, jam or red-bean paste, or savory with minced pork and pickled greens. Sold from carts and tiny shopfronts, it is a coin-sized, eggy, made-to-order bite eaten warm.
Egg hong cake is a Chengdu specialty whose making is traditionally traced to the late Qing. The standard account places it around the twenty-third year of the Daoguang reign (1843), beside the Shishi Academy on Wenmiao Street — the site of today's Shishi High School — where an old vendor surnamed Shi is said to have taken the idea from children playing house ("gugu-yan" in the Chengdu dialect), beating egg into leavened flour with a little brown sugar and griddling it into small cakes. The story is told as the dish's traditional origin rather than firmly documented history. During the war years, when several famous universities relocated to the Huaxiba campus in Chengdu, the cakes were a favorite of students and teachers and earned the nickname "Huaxiba egg hong cake." The double-flavor egg hong cake of the Long Chaoshou restaurant was later named among Chengdu's famous snacks.
The underside is the contrast: griddled to a thin golden skin that gives a faint crackle, while the top half stays pale, soft and spongy, honeycombed with tiny bubbles and rich with egg. Folded warm, it is a half-moon you eat in a few bites; a sweet one runs molten with sugar and nutty sesame, a savory one is salty and savory with hot minced pork and the sour crunch of pickled greens. Light and tender rather than heavy, it is gone in a moment and made fresh for the next.
Two reactions give the cake its texture. The batter is leavened — classically with a little fermented old batter, now often baking soda or yeast — so that gas bubbles form and expand on heating, opening the soft, holey crumb; the brown sugar feeds the yeast and deepens both color and aroma. Because the pan sits over low, steady heat and is filled only partway, the cake cooks mostly from the bottom: the underside browns and crisps through Maillard reactions and a little caramelization of its sugars against the hot metal, while the top stays pale and steam-soft, never flipped. The egg sets the structure and carries the fragrance, and the small thick-walled copper pan holds and spreads a gentle even heat that colors the base without scorching it. Folding the cake while still hot and pliable traps the filling and lets the residual heat melt sugar or warm the meat through.
Variations
Fillings are where the snack opens up. Sweet versions take sesame and sugar, brown sugar, red-bean paste, fruit jam, sweetened milk-cream, or chocolate spread; savory ones take minced pork with pickled mustard greens or sour long-beans (a common ratio is about seven parts meat to three parts pickle), pork floss, ham, salad, even shredded potato. The Long Chaoshou shop's named "double-flavor" cake pairs two fillings in one fold. Stalls compete on the spread of fillings chalked on the board, and a single vendor may offer dozens; the cake is always cooked to order, folded straight from the pan.

How it's made
7 steps · 2 hours 30 min
- 15 min
Beat eggs with brown sugar until dissolved, then whisk in plain flour and water to a smooth, pourable batter.
- 290 min
Leaven the batter — stir in a little fermented old batter, or baking soda or yeast — and rest it until it bubbles, an hour or more.
Watch outRest the leavened batter until it's visibly bubbling — that's the gas that opens the soft holey crumb; skip it and the cake bakes dense.
- 33 min
Heat a small thick copper pan (or heavy skillet) over low heat and lightly grease it with lard.
- 44 min
Ladle in enough batter to part-fill the pan; cover and cook gently until the cake rises and the underside is golden and set.
Watch outCook covered on low until the underside is golden and set — the top stays pale and steam-soft and never gets flipped.
- 51 min
Lay the chosen filling over one half — sesame-sugar, red-bean paste or minced pork with pickles.
- 61 min
Lift the free edge with tongs and fold the cake into a half-moon, pressing lightly to seal.
- 71 min
Slide out and serve at once, while the base is crisp and the filling warm.
