- Rice Flour: This forms the base and gives the cake its light and slightly dense structure.
- Tapioca Starch: Adds a springy chewiness that makes each bite satisfyingly unique.
- Coconut Milk: Brings a creamy, tropical flavor that’s rich and fragrant.
- Sugar: Sweetens the cake perfectly without overpowering the other flavors.
- Active Dry Yeast: Vital for producing the airy honeycomb holes that define the cake’s texture.
- Salt: Enhances all flavors, balancing the sweetness and richness.

How to Make Steamed Vietnamese Honeycomb Cake Recipe
Step 1: Activate Your Yeast
Start by mixing the sugar and active dry yeast with warm water, then set it aside for about 10 minutes. You’ll know it’s ready when it becomes foamy, signaling that the yeast is alive and primed to work its magic on your cake.
Step 2: Prepare the Batter
In a large bowl, combine rice flour, tapioca starch, and salt. Slowly pour in the coconut milk while stirring continuously to avoid lumps. The result should be a smooth, creamy batter, laying the groundwork for the cake’s signature texture.
Step 3: Combine with Yeast Mixture
Pour the foamy yeast water into the flour mixture and stir well until everything is blended evenly. This is also the moment to add pandan extract or green food coloring if you want your cake to have that lovely pandan aroma and vibrant green hue.
Step 4: Let the Batter Rest
Cover the bowl with a clean cloth and leave it in a warm place for 2 to 3 hours. This resting period is essential—it allows the yeast to ferment gently, creating the tiny bubbles that will give the cake its characteristic honeycomb texture.
Step 5: Prepare Your Steaming Equipment
Grease your ramekins or steaming tray with vegetable oil to prevent sticking. Then gently stir the batter to redistribute bubbles before pouring it halfway into the prepared containers, ensuring room for rising.
Step 6: Steam Your Cake
Bring water to a boil in your steamer on medium-high heat, carefully place the ramekins inside without crowding them, and steam for 15 to 20 minutes. Check doneness with a toothpick—it should come out clean when your cake is cooked through perfectly.
Step 7: Cool and Remove
Once done, allow the cakes to cool slightly before removing them gently from the molds. This is where you can admire the gorgeous honeycomb texture before digging in for your first delicious bite!
How to Serve Steamed Vietnamese Honeycomb Cake Recipe

Garnishes
Keep it simple to highlight the cake’s natural flavors—perhaps a dusting of powdered sugar or a few toasted sesame seeds for a subtle nutty crunch. Fresh coconut flakes can also complement the coconut milk in the cake beautifully.
Side Dishes
This cake pairs delightfully with a cup of hot jasmine tea or Vietnamese drip coffee, where the bitterness of the drink balances the cake’s sweet richness. For a more indulgent experience, serve with a scoop of coconut or vanilla ice cream to contrast the warm, chewy texture.
Creative Ways to Present
Try slicing the honeycomb cake into petite squares and threading them onto bamboo skewers with tropical fruits like mango or lychee for an eye-catching appetizer or dessert platter. Another idea is to layer pieces between sheets of banana leaf for an authentic Vietnamese touch that’s both rustic and charming.
Make Ahead and Storage
Storing Leftovers
If you have leftover steamed Vietnamese honeycomb cake, wrap it tightly in plastic wrap or place in an airtight container. Store it in the refrigerator for up to 3 days to keep its texture and flavor fresh.
Freezing
For longer storage, you can freeze the cake by first freezing individual pieces on a baking sheet, then transferring them to a freezer-safe bag. Frozen honeycomb cake keeps well for up to 1 month. Thaw in the refrigerator before reheating.
Reheating
Reheat leftovers by gently steaming them again for a few minutes to restore moisture and texture, or microwave briefly covered with a damp paper towel to prevent drying out. This way, your Steamed Vietnamese Honeycomb Cake Recipe remains just as delicious as freshly made.
FAQs
What makes this cake “honeycomb” in texture?
The honeycomb effect comes from the yeast fermenting in the batter, creating tiny air bubbles that form a spongy, holey texture, which is unique and delightful in every bite.
Can I substitute tapioca starch with cornstarch?
While cornstarch can be a substitute, tapioca starch is preferred because it provides that distinct chewy, springy quality that cornstarch lacks, so the texture might be slightly different.
Is pandan extract necessary?
Pandan extract is optional but highly recommended as it imparts a lovely aroma and attractive green color that enhances the traditional experience of this cake.
How long should I steam the cake if using a large steaming tray?
Steam for about 20-25 minutes if you’re using a larger tray to ensure even cooking, but keep an eye on it and perform the toothpick test to check doneness.
Can I make this cake vegan?
Yes, the cake is naturally vegan since it’s made without eggs or dairy—just plant-based ingredients like coconut milk, so it’s perfect for vegan diets.

- 100 g Sugar
- 2 tsp Active Dry Yeast
- 1 tsp Salt
- 200 ml Warm Water
- 1 tbsp Vegetable Oil
- 2 drops Pandan Extract or Food Coloring
Instructions
- Activate Yeast: In a small bowl, combine the sugar and active dry yeast with warm water. Leave it aside for about 10 minutes until the mixture becomes foamy, indicating the yeast is active and ready.
- Prepare Batter: In a large mixing bowl, sift together rice flour, tapioca starch, and salt. Gradually pour in the coconut milk while continuously stirring until you achieve a smooth, lump-free batter.
- Combine Mixtures: Pour the foamy yeast mixture into the flour mixture and stir thoroughly to blend everything together. Add pandan extract or green food coloring at this stage to lend both color and fragrant aroma to your cake batter.
- Rest the Batter: Cover the bowl with a clean cloth and place it in a warm spot. Allow the batter to rest and ferment for 2 to 3 hours. This resting time helps the yeast develop bubbles essential for the honeycomb texture.

- Steam the Cake: Cover and steam the batter for 15-20 minutes. Test doneness by inserting a toothpick; it should come out clean when the cake is ready.
- Cool and Serve: Remove the ramekins from the steamer and let the cakes cool slightly. Carefully unmold the cakes and serve warm or at room temperature for the best flavor and texture experience.
Notes
- Make sure the water used to activate yeast is warm, not hot, to avoid killing the yeast.
- Resting time is crucial for developing the signature honeycomb texture.
- You can substitute pandan extract with natural green food coloring if pandan is unavailable.
- Use fresh or canned coconut milk for the richest flavor.
- The cake is best enjoyed within a day or two but can be refrigerated and reheated by steaming gently.
- Ensure the steamer lid is covered tightly to prevent water droplets from dripping on the cake surface during steaming.
