Small sponge cakes come fresh out of the oven, dense and moist with a buttery aroma, each one hiding a crumbly, not-too-salty egg yolk at its center — this is bánh bông lan trứng muối, Vung Tau's most representative souvenir dessert of recent years, and one of the most common sights of a queue forming down the sidewalk.
A production-and-sales phenomenon covered by state media
The state outlet Tuổi Trẻ ran a feature in July 2025, 'Bông lan trứng muối Vũng Tàu có gì mà khách mua nhiều dữ?' (What's so special about Vung Tau's salted-egg sponge cake that everyone's buying it?), documenting exactly this cake's production, sales, and the crowds actually buying it. The method involves baking each cake individually in a small charcoal-fired mold, which gives the sponge a faint toasted aroma that mass production can't replicate, paired with a crumbly salted egg yolk — one of Vung Tau's most representative souvenir desserts in recent years.
Honest clarification: the 'first invented by' claim mostly traces back to shop self-accounts or blog citations
It has to be said honestly: claims about which shop 'invented it first' mostly trace back to the shops' own accounts or repeated citations across travel blogs, without any specific official documentation that settles the question. Gốc Cột Điện, at 17B Nguyễn Trường Tộ Street, is cross-referenced by multiple independent travel platforms — including VinWonders and Sun World — as the 'earliest and most famous' shop, though no state-media report verifying that shop's own history or founding date has been found. This guide anchors on Gốc Cột Điện, backed by Tuổi Trẻ's state-media coverage and the highest cross-referencing among independent sources, as a representative point of reference — not an endorsement of it as the settled inventor of the dish.
How to Buy It Freshest
- Fresh out of the oven is best — the buttery aroma fades a bit once the cake cools.
- If carrying it as a souvenir, avoid leaving it in high heat for extended periods.
- Busy queue times usually mean a batch has just come out of the oven — it's worth asking about the shop's baking schedule.
An Honest Look at the 'First Invented By' Claim
- Claims about 'who invented it first' mostly trace back to shop self-accounts or blog citations, with no official documentation confirming the story.
- Gốc Cột Điện is the most cross-referenced by travel platforms, but its own history hasn't been independently verified by state media.
- This guide anchors on the shop with the strongest state-media coverage and cross-referencing, not an exhaustive ranking.
A salted egg yolk sponge cake carries home more than just dessert — it's Vung Tau's sharpest souvenir memory of recent years. As for which shop really made it first, maybe the answer matters less than it seems; the queue outside has already cast its vote.
