Ingredients
Dry Ingredients
- 1 cup tapioca starch (also called tapioca flour)
- 1 tablespoon rice flour
- 1 teaspoon baking powder
- ¼ teaspoon salt
Wet Ingredients
- 4 large eggs (room temperature)
- ¾ cup granulated sugar
- 1 cup coconut milk
- 1 teaspoon pandan extract (or 2 tablespoons fresh pandan juice)
- 2 tablespoons vegetable oil
Optional Garnish
- Toasted coconut flakes
- Powdered sugar
Understanding the Key Ingredients
Before starting, it’s helpful to understand why these ingredients matter.
Pandan
Pandan leaves are widely used in Southeast Asian desserts for their sweet, grassy aroma. The extract gives the cake its signature green color and fragrance.
Coconut Milk
Coconut milk provides richness and moisture, complementing the pandan flavor perfectly.
Tapioca Starch
Unlike wheat flour, tapioca starch creates the cake’s slightly chewy texture and helps form the honeycomb structure.
Eggs
Eggs give the cake its structure and help trap air bubbles during baking.
Step 1: Preheat the Pan and Oven
One of the most important secrets to a successful honeycomb cake is a very hot baking pan.
Preheat your oven to 350°F (175°C).
Place a round 8-inch metal cake pan in the oven while it heats. The hot pan helps create the honeycomb texture once the batter is poured in.
Let the pan heat in the oven for at least 10 minutes before using.
Step 2: Prepare the Coconut Mixture
In a small saucepan, combine:
- Coconut milk
- Sugar
- Vegetable oil
Heat gently over medium-low heat, stirring until the sugar completely dissolves.
Do not boil the mixture; it should just become warm and smooth.
Remove from heat and allow it to cool slightly before adding eggs later.
Step 3: Mix the Dry Ingredients
In a medium mixing bowl, whisk together:
- Tapioca starch
- Rice flour
- Baking powder
- Salt
Sifting the dry ingredients helps prevent lumps and ensures an even texture.
Set this bowl aside.
Step 4: Beat the Eggs
In a separate large bowl, lightly beat the eggs.
The goal is to mix the eggs without creating too many bubbles. Over-whisking can ruin the honeycomb texture.
Stir slowly until the yolks and whites are just combined.
Step 5: Combine Wet Ingredients
Slowly pour the warm coconut mixture into the beaten eggs while gently stirring.
Make sure the coconut mixture is not hot, or it may cook the eggs.
Add the pandan extract and mix until the batter becomes a beautiful light green color.
The fragrance should already start to smell amazing.
Step 6: Add Dry Ingredients
Gradually add the dry ingredients into the wet mixture.
Stir gently with a whisk or spatula until the batter becomes smooth.
Try not to whip or beat aggressively. Gentle mixing helps maintain the structure needed for the honeycomb effect.
Step 7: Strain the Batter
For the smoothest cake texture, pour the batter through a fine mesh strainer.
This removes lumps and ensures a silky batter.
Let the batter rest for 10 minutes. This resting time allows the starch to hydrate properly.
Step 8: Prepare the Hot Pan
Carefully remove the hot pan from the oven.
Lightly grease it with oil or line the bottom with parchment paper.
Immediately pour the batter into the hot pan. You should hear a faint sizzling sound — this is normal and helps create the honeycomb structure.
Step 9: Bake the Cake
Place the pan back in the oven and bake for 40–45 minutes.
Avoid opening the oven door during the first 30 minutes, as this can collapse the cake.
The cake is done when:
- The top is golden brown
- A toothpick inserted comes out clean
- The cake slightly pulls away from the sides of the pan
Step 10: Cooling the Cake
Once baked, remove the cake from the oven.
For best results, turn the pan upside down on a cooling rack.
This prevents the honeycomb structure from collapsing while cooling.
Allow the cake to cool completely before slicing.
Step 11: Slice and Serve
Once fully cooled, run a knife around the edges and remove the cake from the pan.
Cut the cake into wedges and admire the beautiful honeycomb tunnels inside.
Serve it as is or garnish with:
- toasted coconut flakes
- a dusting of powdered sugar
Tips for the Perfect Honeycomb Cake
Use a Hot Pan
The hot pan is essential for creating the honeycomb bubbles.
Do Not Overmix
Overmixing introduces too many air bubbles and can destroy the structure.
Let the Batter Rest
Resting helps the starch absorb liquid and improves texture.
Avoid Opening the Oven
Temperature changes can collapse the honeycomb structure.
Flavor Variations
Once you master the classic recipe, you can experiment with different flavors.
Pandan Chocolate Honeycomb Cake
Add 2 tablespoons of cocoa powder to the batter.
Coffee Coconut Honeycomb Cake
Add 1 teaspoon of instant coffee for a rich twist.
Vanilla Coconut Honeycomb Cake
Replace pandan extract with vanilla extract for a milder flavor.
Storage Tips
This cake stores well and remains soft for several days.
Room temperature:
- Store in an airtight container for 2 days
Refrigerator:
- Keeps for 4–5 days
To reheat:
- Warm slices briefly in the microwave for 10 seconds.
