Bika Ambon is a yellow, bouncy and fragrant cake. It is beautiful with lots of strands from the honeycomb cake texture. Sweet flavor comes with a hint of lime and lemongrass.

It is basically a honeycomb cake. Made with eggs, coconut milk and tapioca flour. The honeycomb texture comes from perfect yeast fermentation.

My first encounter with this wonderful springy cake is when I was in high school. My Mom bought it for me. I liked it right away for the pores and the bouncy texture.

The fascination grew bigger when I bought it myself when I was working in an architecture firm. Someone mentioned a quite famous bika ambon seller in North Jakarta. There was this waiting list that made me wonder.

So, I ordered this Indonesian honeycomb cake for myself. And I was so surprised that this cake could be this delightful. While eating, I kept wondering how on earth could someone create these wonderful pores in the cakes.

It was back then, when I was not interested in baking at all. Now that I entered baking and cooking world, I was intrigued to make it myself.

After several trial and error with many recipes and many baking methods, I decided on a few recipes to keep.


Bika Ambon originated in Medan, North Sumatera. It was named Bika Ambon because it was first sold on Jalan Ambon Sei Kera in Medan. Ambon is actually another province located far away from Medan.

So this Indonesian honeycomb cake is very famous with the name Bika Ambon Medan and if you go to Medan, you will notice that almost everyone will get this cake by boxes as souvenir.

Ingredients That Define The Flavor

Coconut milk mixture

The coconut milk mixture will determine the color, fragrant and texture of the cake. Keffir lime leaves, lemongrass, and pandan leaves will give an aromatic flavor. Ground turmeric will add more yellow color.

Cook the mixture until it boils. The heat will bring out the flavor even more and when you keep the coconut mixture overnight, it will even be more fragrant the next day.

If you want to use the coconut milk on the same day, please remember to leave it to cool to warm to the touch temperature before mixing it with the yeast.

The heat  will kill the yeast instantly, while the warm temperature will help ferment the whole batter perfectly. So, leave the coconut milk until warm before mixing it together with the yeast.

Eggs Or Egg Yolks?

If you research the recipe for Bika Ambon online, you will find that there are recipes that use a lot of egg yolks and some only use two or three eggs.

Egg yolks will give a beautiful yellow color to the cake, especially egg yolks from free range farm. If you use whole eggs, you can add a bit of yellow coloring with turmeric to it.

Let me tell you a sincere story. I was relucant to try making Bika Ambon because of the amount of egg yolks. I was afraid to fail baking it and having used so many eggs.

So you can try the economical version with three eggs I wrote down below. I braved myself with egg yolk version first and later tried the economical version.

Instant yeast

Dry instant yeast is the one ingredient that helps with the fermentation and gives the honeycomb structure of the cake.

Check your yeast before using it. Use warm water and stir well, leave it for 15 minutes. If it is bubbly, the yeast is still good to go.

Back in the old days, people in Medan use neera water that comes from palm’s flower. Its natural sweetness can help the fermentation in Bika Ambon Cake.

In a traditional way, neera water is used instead of instant yeast to form the honeycomb texture.


In my baking experience, I always reduce the amount of sugar in a recipe. To me, making Bika Ambon is quite challenging. The amount of sugar in the recipe is mostly a lot.

At first, I was worried the cake would be too sweet. But later, a friend of mine told me that the sugar will be consumed by the yeast during fermentation process.

The original recipe uses regular white sugar, but you may also use palm sugar or brown sugar. The taste from palm sugar will be more caramel and nutty. But I don’t like the color of the cake.

The original Bika Ambon is bright yellow in color. It looks beautiful and more tempting or maybe I’m just used to it.

When I use palm sugar or brown sugar, the cake’s color becomes light brown. Even though the taste is unique with the caramel nutty flavor, I still like it better with the regular sugar.


The flour used for making this Indonesian honeycomb cake is mostly tapioca flour. It creates a bouncy and chewy texture.

However, there are several recipes combining tapioca flour with cake flour or with glutinous rice flour. The result is still bouncy and chewy.

You may experiment on many different recipes as long as you understand the process and follow the baking method precisely.

Baking Method

This is the crucial part of making Bika Ambon. Even though you have gone through the fermentation process successfully, this part has to be done carefully and thoroughly.

When done correctly, the honeycomb structure will shoot right from the bottom to the top of the cake. The heat must be enough to make the batter bubbly and create the pores.

Let’s go through it one by one!

Electrical Oven

When you use an electrical oven, make sure to preheat it first. Use the lower heat first at 190°C, preheat the baking pan in the oven.

Put the baking pan on the bottom rack of the oven.

After 45 – 60 minutes, turn off the low heat, and move the baking pan on the upper rack, turn on the upper heat 10°C for 5-10 minutes.

In this phase, you really have to pay attention. Do not leave it unattended.

Griddle On Stove

Another way to bake this Indonesian honeycomb cake is to use a griddle skillet made of iron. Put the griddle on top of a stove with medium heat. Preheat the griddle and the baking pan.

When using this method, you can also use a non-stick sauce pan and the lid. Other than that, you can also use a fried egg pan.

Pour the batter only when the baking pan is hot enough it sizzles.

Put on a glass lid or the sauce pan lid if you are using a sauce pan.

Sand On Stove

There is another method. You need a special iron cast pan to fill it with medium grind sand. Then you put the baking pan on top of the sand surface. The sand acts as a heat redeemer just like the skillet.

The process is the same with using a skillet on stove. You need to preheat the sand and the baking pan first with medium heat.

I myself prefer to use the skillet for the practical reason. It is easier to keep the skillet when not in use, rather than keeping the sand and the special iron cast pan.

Greasing The Pan

Most recipes will tell you to grease the pan with oil to prevent sticking. You can brush the oil thinly as the batter itself contains coconut milk.

Line the bottom of the baking pan with parchment paper to prevent sticking.

If you use a non-stick pan, you do not have to grease the pan.


Even though the original Bika Ambon is the most favorite for almost everyone who has ever tasted it, there are many variations created.

Bika Ambon Pandan is the second favorite. It is green and for many pandan lovers, this is also an irresistible option because it is so fragrant.

Jackfruit, durian, chocolate, and cheese are also variations made from this wonderful cake. Nowadays, you can also experiment with matcha green tea and earl grey.

Make sure to eliminate lemongrass and kaffir lime leaves if you want to try strong flavors like earl grey, matcha green tea, chocolate, jackfruit, or durian.

Palm sugar is also another thing to try. Unfortunately, you will lose the golden yellow color, but the palm sugar color will replace it. Anyway, it also has its own unique flavor.


A good Bika Ambon cake will be fine even if you keep it in room temperature for 2 – 3 days. I would not recommend keeping it in room temperature if it is too hot coconut milk tends to go bad fast in hot weather.

Bika Ambon will stay fresh in the chiller for up to 7 days. If you keep it in the freezer, it can stay up to one month.

This is the recipe that I have tried many times. The results have my friends and family’s approval. I am also quite satisfied with the strands of honeycomb in the cake.
