Easy Chinese Honeycomb Rice Cake (Bai Tang Gao)

There is something incredibly satisfying about the texture of a traditional Chinese honeycomb rice cake. I remember my first time trying these at a small dim sum shop in San Francisco. I was fascinated by the intricate, sponge-like holes running through every bite—it felt like eating a delicious, sweet cloud. It took me a few attempts in my own kitchen to really nail that distinct 'honeycomb' structure, but once you understand the role of the yeast and the resting time, it becomes quite a simple process.
Unlike denser cakes, this steamed version relies on rice flour to achieve a delicate bounce. You aren't looking for a heavy crumb here; you want those bubbles to form during the steam, which creates that classic airy interior. I prefer to use a shallow cake pan, as it helps the steam penetrate evenly and ensures the top doesn't become overly gummy. It is a fantastic afternoon snack when you want something light, chewy, and just sweet enough to satisfy a craving.
One tip: don't rush the fermentation process. If the batter doesn't look bubbly before you slide it into the steamer, the result will be flat rather than porous. I like to serve these warm, cut into diamond shapes, perhaps with a dusting of toasted sesame seeds if I am feeling fancy. It is a wonderful way to introduce a bit of traditional technique into your regular baking routine without needing a massive list of ingredients.
Frequently asked questions
+ − Why is my rice cake dense instead of airy?
The most likely culprit is the yeast. Ensure your water is warm—not hot—and that your yeast is still active. If it does not foam or create bubbles during the resting period, the cake will not rise properly.
+ − Can I use glutinous rice flour instead?
No, it is important to use standard rice flour. Glutinous rice flour will result in a heavy, mochi-like texture rather than the light, spongy texture required for a honeycomb cake.
