Honeycomb Cake

Soft, bouncy, and absolutely mesmerizing, Honeycomb Cake is unlike any other dessert. Its golden crust gives way to a vibrant green interior, complete with the signature airy tunnels that give it its name. Lightly sweet, rich with coconut milk, and just a little chewy, this cake is a texture lover’s dream. One slice and you’ll understand why it’s loved by so many across generations and cultures.

Behind the Recipe

This cake brings back memories of my childhood, when the scent of coconut and caramelized sugar would float through the house. My aunt would often make it for gatherings, and we’d all marvel at the mysterious honeycomb-like holes inside every slice. It felt like magic. As an adult, I discovered it was science — a gentle reaction between baking soda and the batter’s warmth. But it still feels a little magical every time it comes out of the oven.

Recipe Origin or Trivia

Honeycomb Cake, often known as “Bánh Bò Nướng” in Vietnamese or “Kek Sarang Semut” in Malaysian cuisine, gets its name from its interior structure. The cake’s bubbly, netted holes are created through a chemical reaction that happens while baking. It’s traditionally made with pandan for flavor and color, giving the cake its bright green hue and a subtle vanilla-like aroma. A beloved dessert throughout Southeast Asia, it’s celebrated not just for its taste but its unique texture and appearance.

Chef’s Pro Tips for Perfect Results

This cake is simple to make, but a few secrets will help you nail that signature honeycomb texture:

• Let the batter rest for at least 30 minutes before baking to develop the bubbles.
• Sift your dry ingredients to avoid clumps that could weigh down the structure.
• Don’t overmix after adding the leavening agent — mix just enough to combine.
• Preheat the oven and pan properly so the reaction starts immediately when the batter hits the heat.
• Slice only when completely cooled for clean cuts and intact tunnels.

Instructions for Making Honeycomb Cake

Let’s walk through how to bring this stunning green dessert to life. It’s easier than you think — just follow the steps and don’t rush the rest time!

1. Preheat Your Equipment:
   Set your oven to 325°F (160°C). Grease a bundt or tube pan and place it in the oven to preheat as well.
2. Combine Ingredients:
   In a large bowl, whisk together the eggs and sugar until the mixture is light and foamy. Add coconut milk, pandan extract, and vanilla extract. Stir to combine.
3. Prepare Your Cooking Vessel:
   In a separate bowl, sift together tapioca starch, flour, baking powder, and baking soda. Slowly add the dry ingredients to the wet mixture, stirring gently until fully incorporated.
4. Assemble the Dish:
   Let the batter rest uncovered at room temperature for 30 minutes. This allows air bubbles to form — don’t skip this!
5. Cook to Perfection:
   Carefully remove the hot pan from the oven and pour in the rested batter. Bake for 45 to 50 minutes, or until a toothpick inserted comes out clean and the top is golden.
6. Finishing Touches:
   Let the cake cool in the pan for 15 minutes before turning it out onto a rack to cool completely.
7. Serve and Enjoy:
   Slice when fully cooled to see the beautiful honeycomb texture inside. Serve with tea or coffee and enjoy every spongy bite.

Texture & Flavor Secrets

The outer crust is firm and golden while the inside remains light, chewy, and filled with tunnels — thanks to the perfect balance of baking soda, temperature, and rest time. The flavor is subtly sweet, creamy from the coconut, and fragrant from pandan.

Cooking Tips & Tricks

Some extra know-how to make your cake a success:

• Resting the batter is essential — it gives you the honeycomb holes.
• Use room-temperature eggs and coconut milk to keep the batter smooth.
• Grease the pan well and heat it to prevent sticking and kickstart rising.

What to Avoid

Don’t let small mistakes deflate your cake! Here’s what to watch for:

• Skipping the rest time: You’ll lose the signature tunnels.
• Cold ingredients: Can shock the batter and flatten the texture.
• Overbaking: Dries out the sponge and reduces bounce.
