Direct answer: Fluffy Cantonese ma lai go needs a rested yeast batter, fresh baking powder added shortly before steaming, and strong uninterrupted steam. Pour the batter into a fully preheated lined pan, steam for 30 to 35 minutes, and wait 5 minutes before opening the lid to prevent collapse.
Key takeaways
- Use dark brown sugar for the characteristic color and caramel flavor.
- Let yeast ferment the batter until visibly bubbly.
- Add baking powder only after fermentation.
- Preheat the steamer before the cake goes in.
- Do not open the lid during the first 30 minutes.
What is ma lai go?
Ma lai go is a Cantonese steamed sponge cake served at dim sum. It has a moist, springy crumb, a deep golden-brown color and open honeycomb pores. Unlike an oven cake, it cooks through condensation-free steam and does not develop a dry crust.
Traditional bakery formulas may use long fermentation or specialized leavening. This beginner version combines a short yeast fermentation with baking powder. Yeast builds flavor and bubbles; baking powder supplies dependable lift during steaming.
Ingredients for one 8-inch cake
- 1 1/2 cups/180 g cake flour
- 1/2 cup/100 g dark brown sugar, packed
- 1/4 cup/50 g granulated sugar
- 1/2 cup/120 ml evaporated milk
- 1/3 cup/80 ml warm water at 95 to 105 F/35 to 41 C
- 1 teaspoon/3 g instant yeast
- 3 large eggs, room temperature
- 3 tablespoons/42 g unsalted butter, melted and cooled
- 1 teaspoon vanilla extract
- 2 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
Preparation takes 20 minutes, fermentation 60 to 90 minutes, and steaming 30 to 35 minutes.
Step 1: dissolve the sugar
Combine brown sugar, granulated sugar, evaporated milk and warm water. Stir until most crystals dissolve. The mixture should feel warm, not hot. Liquid above about 120 F/49 C can damage yeast and may begin cooking the eggs.
Step 2: mix the batter
Whisk cake flour, yeast and salt. In another bowl, beat eggs until combined, then whisk in the sugar mixture and vanilla. Add wet ingredients to flour in three portions, whisking gently until smooth.
Pass the batter through a fine strainer to remove flour lumps. Cover and leave at 75 to 80 F/24 to 27 C for 60 to 90 minutes.
Step 3: judge fermentation
The ready batter should increase by roughly one-third, show many bubbles at the surface and smell mildly yeasty. If the room is cool, allow more time rather than moving it onto direct heat.
Do not wait for a dramatic doubling. Overfermented batter can taste strongly alcoholic and may collapse before steaming.
Step 4: prepare the pan and steamer
Line an 8-inch/20-cm round cake pan with parchment on the bottom and sides, leaving a 2-inch/5-cm collar above the rim. Lightly oil the parchment.
Set a rack in a large covered wok or pot and add 2 inches/5 cm water below it. Bring to a full boil. Check that the pan sits level and the lid closes without touching the parchment collar.
Step 5: add final leavening
Whisk baking powder and baking soda with 1 tablespoon of the fermented batter in a small bowl until smooth. Fold this mixture back into the main batter, then fold in cooled melted butter.
Mix just until uniform. Vigorous beating removes fermented gas, while long delays reduce the baking powder's lifting power.
Step 6: pour and steam
Pour batter into the lined pan from a low height. Tap the pan once to release only very large bubbles. Place it over vigorously boiling water and cover immediately.
Steam over medium-high heat for 30 minutes without opening the lid. Check at 30 minutes: the top should be set and spring back, and a skewer in the center should emerge without wet batter. Steam up to 5 minutes more if needed.
Step 7: prevent collapse
Turn off the burner and keep the lid closed for 5 minutes. Open it gradually, angling condensation away from the cake. Sudden cold air and water droplets can shrink or mark the surface.
Cool in the pan for 10 minutes, then lift onto a rack. Slice when warm rather than piping hot so the crumb does not compress.
Substitutions
No cake flour
For each cup, measure 1 cup all-purpose flour, remove 2 tablespoons and replace them with 2 tablespoons cornstarch. Whisk and sift well.
No evaporated milk
Use whole milk. Flavor will be lighter and the batter may need 2 to 3 extra minutes steaming.
Light brown sugar
It works but produces a paler cake with less molasses flavor.
Neutral oil instead of butter
Use 3 tablespoons. Butter supplies bakery aroma, while oil keeps the crumb slightly softer when cold.
Common mistakes
The cake is dense
Yeast was inactive, fermentation was short or final leavening was old. Check yeast freshness and use newly opened baking powder.
The center is gummy
Steam was weak or the pan too deep. Maintain a steady boil and steam until a skewer has no wet batter.
The cake collapses
The lid opened early, fermentation went too far or the center was undercooked. Follow the closed-lid rest.
The top is wet
Condensation dripped from the lid. Wrap a metal lid with a secured clean towel, keeping fabric far from the burner.
The crumb has no honeycomb
The batter did not ferment visibly or was beaten after leavening. Look for surface bubbles and fold gently.
Food safety and storage
Do not taste raw batter. Raw flour and eggs can contain harmful germs. Steam until the center is fully set; an instant-read thermometer should register at least 190 F/88 C in the cake center. Wash tools and surfaces after raw batter contact.
Refrigerate leftovers within 2 hours and use within 3 to 4 days. Re-steam slices for 3 to 5 minutes until hot, or microwave covered briefly. Freeze wrapped slices for up to 2 months and thaw before reheating.

FAQ
Does ma lai go contain yeast?
Many versions do. This recipe uses yeast for flavor and initial bubbles, then baking powder for reliable steaming lift.
Can I steam it in a bamboo basket?
Yes, if the cake pan fits with space around it and the lid closes fully.
Why use a parchment collar?
It prevents sticking and supports the cake if it rises above the metal pan rim.
Can I ferment overnight?
Not with these timings. Long fermentation changes acidity and leavening; use a formula specifically designed for overnight resting.
How do I reheat ma lai go?
Steam slices for 3 to 5 minutes. Gentle steam restores moisture better than dry oven heat.
Conclusion
Successful ma lai go comes from two controlled rises: visible yeast fermentation in the bowl and fresh chemical leavening in the steamer. Preheat fully, avoid opening the lid, confirm the center is set, and rest before exposing the cake to cool air.
