Pandan Honeycomb Cake (Banh bo nuong)

by Cindy Her

Hello Foodie!
Welcome to another SouthEast Asian dessert recipe! Honeycomb Cake: also known in Vietnamese as Banh Bo Nuong and Bika Ambon in Indonesia. Pandan honeycomb cake is a very popular Vietnamese dessert as well as an Indonesia dessert called Bika Ambon but made slightly different from the Vietnamese version. It has a nice honeycomb like crumb after it’s done baking. The texture is spongy but soft on the inside; chewy and slightly crispy on the outside. It’s sweet, coconutty, and has a hint of pandan flavoring. It’s quite a unique but also pleasant dessert. In Indonesia, instead of the beautiful green pandan color, it’s made with turmeric which gives it the beautiful golden yellow color. It’s also flavored with kaffir lime leaves, lemongrass, and other spices. Quite different from the pandan honeycomb cake but it still has the unique honeycomb shape in the middle.

Today, I’ll be showing you how to make the Vietnamese version, pandan honeycomb cake. Simple ingredients but it can be quite technical. If the eggs are over whipped, the cake will fall after baking. If the baking powder is not active, you will not have the honeycomb structure. If you use too much flour, the cake will be dry. If you bake it too long, the cake will be dry. There are lots of ways this cake can go wrong. I have worked on this recipe 3 times and finally found the right portions to make it to the way I like it. It has not failed me yet. Hopefully you can try out this recipe and get the results you want. Trust me, I’ve tried lots of different recipes and have failed at least 3 times. This one has been my charm. Happy baking! 🙂

TIPS for a successful cake:

  1. Make sure the double acting baking powder is active/working
  2. Do not over whip the eggs. And make sure the eggs are at room temp.
  3. Preheat the oven with the pan in
  4. Use a good quality non-stick pan

Main Ingredients

This recipe uses both tapioca starch and rice flour. Other ingredients include coconut milk, coconut oil, salt, sugar, eggs, baking powder and pandan extract. Now lets talk about baking powder. Most recipes calls for the Alsa brand SINGLE acting baking powder. But in my recipe, I’ll be using DOUBLE acting baking powder. What’s the difference? Single acting baking powder reacts immediately when it is mixed in with liquid. Double acting will react twice; in liquid and in heat. The reason why we’re using double acting baking powder is to create a better honeycomb crumb. Once you put the cake into the oven, the cake will rise even more with the double acting baking powder.

THE EGGS:

Do not over whip the eggs. If you do, your cake will deflate when it cools, which causes uneven air pockets and an uneven cake. Mix just to break apart the yolk and incorporated somewhat with the whites like this
Heat up the coconut milk, sugar, and salt: This helps with melting the salt and sugar crystals; giving the cake a shinier exterior
Mix in everything. There will be lumps, and thats okay. It will be put through a sieve. Bake for 40-45 minutes Using a good non stick pan will help release the cake beautifully
Cut the cake and see the results Soft, spongy, chewy, and delicious
UBE FLAVOR 🙂
BEAUTIFUL!CLOSER LOOK AT THE CRUMB Enjoy the sweet chewiness goodness 🙂

Pandan Honeycomb Cake (Bánh bò nướng)

Serves: 6-8 Prep Time: Cooking Time:
Nutrition facts: 200 calories 20 grams fat

Ingredients

  • 2 cups tapioca flour or starch (265 grams)
  • 1/4 cups rice flour (34 grams)
  • 1 Tbsp double acting baking powder (NOT single acting) (15grams)
  • 1 (14 fl oz) can coconut milk (I use Aroy-D brand) (400ml)
  • 1 1/4 cups sugar (260grams)
  • 1 tsp salt (6grams)
  • 1 tsp pandan extract or more (6grams)
  • 6 eggs (room temp) (300grams)
  • 2 tbsp melted coconut oil (or other neutral oil of your choice) (26grams)

Instructions

1) Preheat the oven to 350' with the baking pan inside to heat up.

2) In a small pan, add in the coconut milk, sugar, and salt. Heat until the sugar is dissolve but not boiling. You should feel no grittiness on the bottom. Let it cool over ice water if needed for faster preparation. Set aside.

3) In a bowl, measure out the tapioca flour, rice flour, and double acting baking powder. Whisk well. Set aside.

4) In another bowl, crack 6 eggs. With a fork, gently poke the yolks and break it apart along with the whites but do not whisk or create any air bubbles. This will cause too much air pockets in the cake during baking time which cause the cake to deflate once it's cooled. Then add in the cooled coconut sugar mixture and add in 1 tsp of pandan extract. Add more pandan if it's too light for you. Mix gently. Then add in the dry ingredients and mix gently. There will be chunks of the starches, but that's okay. The batter will go over a strainer. You just want to mix the starch well enough into the eggs/coconut sugar mixture just so it's hydrated (again, don't create too much air pocket).

5) Then pour the chunky batter over a bowl with a strainer. Use a spatula to break apart any chunky parts. Once it's been well strained, add in the melted coconut oil. Mix gently. By this time the oven should be preheated and the pan should be nice and hot.

6) Get the pan out of the oven and spray it generously with cooking spray. Pour the batter on and stick it back to the oven. Let it cook for at least 40-45 minutes until the cake is cooked in the middle. I cooked mine for 45 minutes. Then turn off the oven heat, open the oven door slightly and let the cake rest inside for 20 minutes.

7) After 20 minutes of resting, take the cake out, flip it over on a board and cut. You can cool it longer if it's too hot to handle. Cut into your desire size and enjoy! YUM!

Notes

You can use any extract to flavor this cake: Pandan, ube, coffee, vanilla etc. If you want to do ube flavor, I suggest adding 1 tsp ube flavoring/extract instead of pandan extract. Add more if you desire a deeper dark purple color. This cake will stay soft in room temperature for 2 days. Refrigerate if not eaten in 3-4 days. Heat for 15 sec in the microwave to return to its softness if refrigerated.

You can try. The cake may be a little more sticky and chewy.

Hi Cindy,

Great tutorial! Thanks for sharing. After couple of tries, I still can’t seem to get the honeycomb. I followed your steps to a tee, and the only variant to your recipe is a different brand of the tapioca starch. Do you think that is issue?

Hi! I had a bad time the first time but on the second try I used 1 egg less (mine where too big) cook it for 30 min turn off the oven, left it on the oven without open the door for other 15 min and then open the oven door 1-2 inches (you can stick a wooden spoon) for about 30 min, I also cut the yolks with scissors to avoid air into the mix

So if I use any flavor other than pandan or Ube, would I use 1 teaspoon? I want to try it with coffee flavor, but I’m not sure if I need more than 1 teaspoon. I love your recipe!!!

I just made it and the cake wasnt as honeycomb texture. It was good but more dense? Any recommendations?

Reply
Cindy Her July 25, 2020 - 10:11 pm

It could of been a lot of things. It may have been your pan, the oven wasn’t hot enough, the baking powder wasn’t as active. Did you use cold or room temp eggs?

Reply
Joanne August 21, 2020 - 7:27 pm

I tried the recipe down to the “T” and still failed. It seems too dense. Not sure if it’s the pan or what. Only a 1/4 of the cake looked honeycombed. Any input on what went wrong?

Reply
Cindy Her August 21, 2020 - 10:23 pm

It could be a number of factor. It could have been the pan or the oven. Did you use the right flour as well? I had a few message me saying they have the same issues as yours and noticed they used glutinous rice flour instead of regular rice flour. It could have been the baking powder as well. If it’s not active, it could cause it to only do 1/4 honeycomb. Were your eggs at room temp as well?

Does it matter if you put the salt in the dry mix versus the coconut sugar mix!

Reply
Cindy Her March 3, 2021 - 1:48 am

I would add it to the coconut sugar mix

Hi Cindy, I have made you cake numerous times and each time is different. I have looked at your recipe again and the bowl with the eggs. You have 7 eggs in the bowl but recipe says 6. Is it 6 or 7 eggs? Really trying to achieve the honeycomb look

I untried it and it was beautifully puffed up in the oven. I let it rest in the oven open… had a meeting for work came back to a pancake! :(. Did it sit too long in the oven?

Reply
Cindy Her February 17, 2022 - 2:58 am

You probably opened the oven too fast and it deflated real quick. After it’s done cooking, turn oven off, let it sit for 5 minutes or so and then open the oven door. Your oven watt might be higher than mine as well so that will also depend on why it deflated.

I love watching all of your videos! Thank you for sharing. It gives me so much nostalgia. Food is such a great way to pass down our culture and traditions. I made this cake today and it turned out beautiful. Thank you again!

Hi! The first time I made it, it was perfect! This time, I purchased the wrong pandan extract, the store I went to only had pandan essence and even though the liquid is green, it’s very light and the batter had no color. I even added extra, but that didn’t help. Will you please share which pandan extract you use? The first time, I used the butterfly brand. This time around, the cake smells more eggy.

What is the pan size for this recipe? Do you have the recipe for 6 or 7 inches pan?

Reply
Cindy Her October 3, 2023 - 2:49 am

This recipe will work to split between two 6 inch round pans.

Awesome recipe! I baked it in a bundt pan. Banh bo nuong is notoriously finicky but I my first time making it with this recipe was a success. Will definitely be making this again, my Vietnamese parents loved it.

Thanks for the receipe, I will try to bake it soon.
With rice flour do you mean glutinous rice flour (like for mochis) or rice flour that doesnt stick? I only have the first one at home.

Thank you!

Reply
Cindy Her February 8, 2024 - 3:29 am

This recipe calls for rice flour (the one that doesn’t stick)

Have you baked this in one round baking pan? Would you bake this recipe in an 8 inch or 9 inch round pan?

Hi Cindy! I’ve been looking for the perfect recipe for years. I think yours really hit the spot! My Pandan cake is finally perfect!! I’m surprised the double-acting baking side worked so well. I always used the Alsa single acting.

Also, I did add one thing… I used 1 cup of cane sugar and added 1 packet of Vanilla Sugar, melted that with the salt and coconut milk. This helped the flavor a little more, subtle change.

I also used your recipe and it made 6 mini-Bundt cakes! It was perfect to make many and share on Tet with family and friends!

I am so thankful for your video!!! Thank you for sharing the perfect recipe! <3

Delicioso! And I have the honeycomb structure as well. If I could submit a photo I would . Thank you.

I’m so happy the texture turned out like it was supposed to! I was so scared I was going to do something wrong, especially since baking isn’t my forte. I didn’t like the salty taste though. I don’t know if it was because of the type of salt I used or the cooking spray, but next time I’ll just do a pinch of salt or add more sugar.

Reply
Cindy Her April 3, 2024 - 2:56 am

It must have been the type of salt you used. If you use table salt or regular Morton salt, it’s much saltier than sea salt/Himalayan salt.
