Coin-sized rice-flour cups fried in a dimpled cast-iron pan, topped with a whole shrimp, mung bean paste, and scallion oil; eaten wrapped in lettuce and herbs with nuoc cham.
Banh khot is the Vung Tau coastal specialty of Ba Ria-Vung Tau province in southern Vietnam, popularized in the mid-20th century. The dimpled cast-iron pan (also called khuon banh khot) is the defining tool — without it the cake can't form its cup shape with crisp wall and yielding centre. Coconut milk, turmeric, and shrimp mark this as a Mekong-coast preparation rather than the lard-based banh xeo. Vung Tau has a banh khot quarter where competing stalls have served it for decades.
Vung Tau coastal specialty (Ba Ria-Vung Tau province) popularized mid-20th century. The dimpled cast-iron khuon banh khot is non-substitutable — without the hemispherical well you can't form crisp wall and yielding centre. Coconut milk drives Maillard browning at the rim; turmeric is colour, not flavour.
A bite-sized cup the diameter of a 50-cent coin, deep gold and crackly at the rim, soft-set in the middle from coconut milk. The shrimp on top is just-cooked, sweet; the mung bean paste under it adds starchy weight. Wrapped in mustard leaf with herbs and dunked, you get crunch-then-melt-then-herb-then-tang in one bite. A bad banh khot is pale and uniformly soft — the well-fired batch is dark-edged and audible.
The cup shape is mechanical: rice batter poured into a hot, oiled hemispherical well sears the wall in 30 seconds, and that ring of cooked starch holds the rest of the batter as it sets from the bottom up. Coconut milk's fat and sugar drive Maillard browning at the rim while keeping the centre tender; pure water-based batter would crisp uniformly and crack. Turmeric is colour, not flavour. The shrimp must go on after the batter has half-set, otherwise it sinks and the cake collapses around it.
Variations
Vung Tau's Goc Vu Sua and Ba Hai are the two competing reference houses on the banh khot quarter; Saigon versions run larger and softer-edged; banh xeo is the related larger-pan crepe cousin without the cup shape.

How it's made
6 steps · 40 min active + 20 min waiting
- 15 min
Whisk 200g rice flour, 30g cornstarch, 1 tsp turmeric, 1 tsp salt with 400ml coconut milk and 200ml water. Rest 20 minutes — the batter should pour like single cream.
- 225 min
Steam 100g split mung beans 25 minutes until soft, mash with a pinch of salt to a coarse paste. Peel and devein 24 small shrimp, leaving tails on.
- 33 min
Heat the dimpled banh khot pan over medium-high until a drop of water dances. Brush each well generously with neutral oil — they should sizzle.
Watch outFlick a drop of water in — it should skitter and hiss across the well; if it just pools, the pan's not hot enough to sear the batter ring.
- 44 min
Pour batter into each well to two-thirds full. Drop a teaspoon of mung bean paste in the centre, then press a shrimp on top. Cover 3 minutes — edges crisp, centre sets.
Watch outPour the batter first and let it half-set before the shrimp goes on — drop shrimp on wet batter and it sinks, collapsing the cake around it.
- 53 min
Spoon scallion oil (60ml hot oil over 4 sliced scallions) over each cake. Cook another minute uncovered until the rim is dark gold and curls inward. Lift out with a thin spoon.
Watch outPull them when the rim goes dark gold and curls inward off the pan — that curl is your release signal, and a thin spoon lifts them clean.
- 62 min
Serve hot with mustard greens, lettuce, perilla, mint, and rau ram (Vietnamese coriander). Each cake gets wrapped leaf-around-cake, dunked in nuoc cham (3 tbsp fish sauce, 3 tbsp sugar, 3 tbsp lime, 6 tbsp water, garlic, chile).
