Taiwan Egg Cake Recipe: Steamed Vanilla Bean Swirls With Crispy Top

This Taiwan egg cake recipe delivers the perfect balance of crispy top and tender, custardy layers—just like the ones sold at bustling night markets. ✨ The secret lies in steaming egg layers with vanilla bean swirls, creating a delicate texture that's both rich and light.

I've perfected this recipe after countless batches, ensuring every slice has that signature golden crust and creamy interior.

The process begins with whisking eggs until pale and fluffy, then carefully layering them in a heatproof dish before steaming. This method transforms simple eggs into a luxurious dessert with minimal effort.

For extra indulgence, I recommend adding a layer of red bean paste or custard in the center, creating a stunning swirl pattern when sliced.

What makes this recipe truly special is its versatility—it's equally delicious as a dessert or snack, and the crispy top holds up beautifully even when sliced hours later. The aroma of vanilla and warm eggs fills your kitchen, making it impossible to resist trying another slice.

Whether you're serving it at a family gathering or enjoying a quiet afternoon treat, this Taiwan egg cake is sure to impress. The contrast of textures—crispy top, soft interior, and creamy filling—makes every bite unforgettable. Let's get started!

Ingredients for taiwan egg cake

Twelve eggs, a vanilla bean, and a touch of butter transform into crispy-topped, custardy magic.

The eggs are the star, so grab the freshest you can find—local farms or grocery store refrigerated cases are your best bet. Room temperature eggs whisk up much easier, so take them out 30 minutes before you start. For the vanilla bean, Madagascar bourbon or Tahitian beans add the most depth, but any quality bean works. I always buy extra because the leftover seeds freeze beautifully for future desserts. The red bean paste? Asian grocery stores have the best selection—look for the smooth, spreadable kind, not the chunky version.

No vanilla bean? Double the vanilla extract and add a pinch of cinnamon for depth. Short on red bean paste? Sweetened mashed banana or apricot jam works in a pinch, though the texture will differ. The custard powder is optional but gives that signature night-market richness—Bob's Red Mill is my go-to brand. For the butter, European-style unsalted (like Plugrá) melts smoother than American brands. And if you're feeling fancy, swap the vegetable oil for avocado oil—it's more stable at high heat.

This cake reheats beautifully—just wrap it in foil and warm for 10-15 minutes at 300°F. Store leftovers in the fridge for 3-4 days, but honestly, it's best on day one. The crispy top softens over time, so if you're making it ahead, re-crisp the top quickly in the oven before serving. For extra indulgence, drizzle with warm honey or chocolate sauce before slicing. The aroma alone will have everyone gathering around your kitchen.

Step-by-step instructions for Taiwan egg cake

Here's how to make this classic steamed cake with a golden top and swirled vanilla goodness.

Spread the 1 cup red bean paste evenly in the bottom of a greased 8-inch round cake pan or steaming dish. Use the 2 tablespoons vegetable oil to lightly coat the pan first—this prevents sticking and makes cleanup easier. Press the paste down gently with a spatula so it forms an even layer about ¼-inch thick. The paste should cover the entire bottom completely, as this will be your flavor base.

Here's the thing—don't worry if it looks uneven at first. As you steam it, the heat will help it settle. I like to use a butter knife to smooth out any rough edges before moving to the next step. This layer needs to be perfectly flat so the egg batter doesn't pool in any spots during steaming.

In a large mixing bowl, combine the 12 whole large eggs, 1 cup granulated sugar, 1 teaspoon vanilla extract, 2 tablespoons custard powder, and ¼ teaspoon salt. Use a hand mixer or stand mixer with whisk attachment to beat on medium-high speed for about 5 minutes until the mixture turns pale yellow and triples in volume. You'll see ribbons form when you lift the whisk—this is your signal the batter's ready.

While mixing, scrape down the sides of the bowl with a spatula every 30 seconds to ensure everything incorporates evenly. The custard powder is key here—it gives that signature Taiwanese texture. If you're using the optional ½ cup water, add it now and mix for another 30 seconds to combine completely. The batter should be smooth with no lumps, and it'll be slightly thicker than regular cake batter.

Scrape the seeds from the whole vanilla bean and set aside. Pour about ⅓ of the egg batter over the red bean paste layer in the prepared pan. Using a butter knife, spread it out evenly, leaving a ½-inch border around the edges. This border prevents overflow during steaming.

Now for the swirls: Sprinkle half of the vanilla bean seeds over the batter, then pour another ⅓ of the batter on top. Use the knife to create gentle swirls in a circular motion from the center outward. This creates those beautiful marbled patterns you see in traditional Taiwan egg cakes. Finally, pour the remaining batter and sprinkle the remaining vanilla seeds on top. Gently tap the pan on the counter once to release any air bubbles.

Place the pan in a steamer basket lined with parchment paper (to prevent sticking) and steam over medium-high heat for 25-30 minutes. The cake is done when the top is just set—it should still look slightly jiggly in the center, like a custard. If you cut into it too early, it'll be runny, but if you wait too long, it'll be dense.

Here's my pro tip: If you don't have a steamer, you can use a colander over a pot of simmering water. Just make sure there's enough water to create steam but not so much that it touches the pan. The steam should be gentle and even—too much heat will make the top cook too fast and become tough. Check at the 20-minute mark to see if it's rising properly.

Once steamed, transfer the cake to a baking sheet and place it under a broiler for 2-3 minutes. Watch it closely—you want the top to turn golden brown and develop a crispy layer. This is where the 2 tablespoons melted butter come in handy: brush it over the top right before broiling for extra richness and that signature caramelized finish.

If your broiler is strong, you might need 1-2 minutes instead. The moment it starts to brown, pull it out immediately. The cake will continue cooking from residual heat. Let it cool for 10 minutes before slicing—this allows the layers to set properly and makes for cleaner cuts. Serve warm with a dusting of powdered sugar or a drizzle of honey for that authentic Taiwan egg cake experience!

Perfect pairings for this recipe

Tea Pairings

Taiwan egg cake's delicate vanilla notes and creamy texture pair beautifully with jasmine tea—its floral aroma complements the dessert without overpowering. I recommend high-quality loose-leaf jasmine pearls from Taiwanese tea houses like Yun Shun Tea for that authentic experience. Serve it warm to enhance the vanilla's warmth. 🍵

Coffee Contrasts

For a bold contrast, try pairing with Taiwanese milk tea—the creamy, slightly sweet profile balances the cake's crispy top and custardy layers. I love Hong Kong-style milk tea with its strong Ceylon tea base and evaporated milk richness.

The bitterness cuts through the sweetness beautifully. For a lighter option, cold brew with condensed milk works perfectly.

Fruit Complements

Fresh mango slices or lychee add a tropical twist that enhances the vanilla's natural sweetness. The acidity in mango brightens the dessert's richness, while lychee's floral notes mirror the vanilla. I like to serve them chilled in a small bowl alongside the cake for a refreshing contrast. 🍈

Dessert Sauces

Drizzle with warm black sesame sauce (mix 2 tbsp tahini, 1 tbsp honey, and 1 tsp soy sauce) for a nutty depth that pairs perfectly with the red bean filling.

Another favorite is chocolate ganache—melt ½ cup dark chocolate with ¼ cup heavy cream and drizzle over slices. The contrast of chocolate and vanilla is pure magic. 🍫

Seasonal Adaptations

In summer, serve with cooling coconut milk or pandan jelly to balance the cake's warmth. For winter gatherings, pair with spiced chai tea—the cinnamon and cardamom notes create a cozy, aromatic experience. The cake's custardy texture stands up beautifully to these seasonal drinks. ❄️
