Asian Style Sponge Cake Recipe: Light and Airy With Matcha Infusion

This Asian-style sponge cake delivers the signature light, airy texture that makes it irresistible—perfect for celebrations or afternoon treats. ✨ The secret lies in precise egg separation and gentle folding, creating layers of delicate foam that stay moist for days. I've perfected this recipe after years of testing, balancing traditional techniques with modern convenience for home bakers.

The key to success begins with room-temperature ingredients and a 325°F oven, which ensures even baking without drying out the delicate crumb. Matcha powder adds an elegant earthy flavor, but you can easily adapt this recipe with pandan or vanilla for different variations. Each component—from the egg whites whipped to stiff peaks to the careful incorporation of sugar—works together to create that signature fluffy yet tender texture.

What you'll achieve is a cake that's light enough to float on air yet sturdy enough to hold fillings like red bean paste or whipped cream. The exterior stays soft and tender, never dry, while the interior remains perfectly moist. This is the kind of dessert that elevates any gathering, whether served as a single slice or cut into elegant layers for a crowd.

For presentation, dust with powdered sugar or garnish with fresh berries to complement the matcha's vibrant green hue. The cake keeps well at room temperature for up to 3 days, making it ideal for meal prep or special occasions. Let's get started on creating this showstopper dessert.

Ingredients for asian style sponge cake

Room-temperature ingredients and precise measurements create this signature light, airy cake.

The matcha powder is the heart of this recipe—ceremonial grade from a Japanese market gives the best vibrant green color and clean flavor. Ikea or World Market often carry it, but any high-quality brand works. Sift it thoroughly to avoid clumps, and measure carefully—too much can make the cake bitter. For the butter, room temperature is critical—press it between parchment paper with a rolling pin if needed. The egg whites and yolks must be at room temperature too; cold eggs won't whip properly. I always use Diamond Crystal baking powder for the most reliable rise, but any brand works if it's fresh.

No matcha? Pandan extract or vanilla bean paste works beautifully—just halve the amount. The vanilla extract can be swapped for vanilla bean paste if you want more depth. For the sugar, superfine is idealegg whites from a carton work too, but fresh is always better. The powdered sugar for dusting can be swapped for confectioners' sugar if that's what you have.

This cake keeps beautifully—3 days at room temperature or 1 week refrigerated in an airtight container. For longer storage, slice and freeze portions between parchment paper for up to 3 months300°F for 5-10 minutes to restore its softness. I always wrap it in plastic wrap directly after baking to lock in moisture. The matcha flavor actually improves slightly over time—perfect for making ahead for celebrations.

Step-by-step instructions for Asian style sponge cake

This method delivers a delicate, airy matcha-infused sponge with a tender crumb and vibrant green hue.

In a medium bowl, cream the 0.5 cup unsalted butter and 0.5 cup powdered sugar together until light and fluffy, about 3-4 minutes using an electric mixer. This creates the perfect base for our filling. In a separate small bowl, whisk together 2 tbsp matcha powder with 2 tablespoons of the beaten butter mixture until smooth and vibrant green.

Combine the matcha mixture back with the remaining buttercream, mixing until evenly distributed. The filling should be bright green and hold its shape when piped. Cover and chill in the refrigerator for at least 30 minutes—this ensures it stays firm when we assemble the cake later. The matcha will infuse beautifully into the buttercream, creating that signature earthy flavor and vibrant color.

In a separate, immaculately clean bowl (any grease will prevent proper whipping), combine the 8 whole large egg whites and 0.25 tsp cream of tartar. I use a stand mixer with the whisk attachment for this step—it's crucial to achieve perfect peaks. Gradually add 1.5 cups granulated sugar while mixing on medium-high speed, about 1 tablespoon at a time, until fully incorporated.

Increase the speed to high and whip for 5-7 minutes until the egg whites form stiff, glossy peaks that hold their shape when the whisk is lifted. You'll know they're ready when the peaks stand straight up and the mixture looks like thick, shiny meringue. This step is critical—under-whipped egg whites will result in a dense cake, while over-whipping can cause deflation. Tap the bowl gently; if the peaks hold, you're good to go.

In a separate bowl, sift together 1.5 cups all-purpose flour, 0.5 tsp baking powder, and 0.25 tsp salt. This ensures a light, airy texture without lumps. Using a rubber spatula, gently fold one-third of the dry ingredients into the egg whites, being careful not to deflate them. The mixture will look slightly streaky at this point—that's normal.

Add the 4 whole large egg yolks mixed with 1 tsp vanilla extract to the bowl, then gently fold in the remaining flour mixture. Fold just until combined—no more than 10-12 strokes—to maintain the airiness. The batter should be thick but still hold its shape when spooned. If it looks too runny, fold in a bit more flour. This delicate folding technique is what creates that signature Asian-style sponge cake texture—light, airy, and tender.

Preheat your oven to 350°F. Grease an 8-inch round cake pan and line the bottom with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Place the pan in a larger baking dish and add hot water to create a water bath—this helps the cake bake evenly and prevents cracking.

Bake for 35-40 minutes until the top springs back when gently touched and a toothpick inserted into the center comes out clean. The cake should be golden on top but still tender—overbaking will make it dry. I like to check the cake at the 30-minute mark to ensure it's baking properly. Once done, remove from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

Once the cake has cooled completely, level the top if needed and cut it horizontally into two equal layers. Place the first layer on a cake stand or plate and spread a thin layer of the chilled matcha buttercream. Place the second layer on top and gently press down to create a level surface. Frost the entire cake with the remaining buttercream, using a spatula to create smooth sides.

For a professional finish, I like to dust the cake with a light layer of powdered sugar using a fine-mesh sieve. This not only adds a beautiful, snowy finish but also enhances the matcha flavor. Chill the cake in the refrigerator for at least 1 hour before slicing—this allows the layers to set and makes for cleaner cuts. Serve at room temperature for the best texture and flavor.

Essential equipment for this recipe

Stand Mixer Essentials

A high-quality stand mixer with a whisk attachment is non-negotiable for this recipe. I use my KitchenAid Artisan Series—its powerful motor handles the demanding task of whipping 8 egg whites to stiff peaks without overheating. The whisk attachment must be clean and free of grease, as even traces can prevent proper aeration. If you don’t own a stand mixer, a hand mixer with a balloon whisk attachment works, but be prepared for more elbow grease and careful monitoring. 💫

Precision Scale

For accurate measurements, especially with delicate ingredients like matcha powder and cream of tartar, a digital kitchen scale is essential. I recommend the OXO Good Grips model—it’s affordable, precise to 0.1 grams, and easy to use. Weighing ingredients by grams ensures consistency, especially when dealing with small amounts like 0.25 tsp cream of tartar. For volume measurements, use a stainless steel measuring cup for flour and sugar to avoid plastic residue affecting texture.

Baking Pans

An 8-inch round cake pan is ideal for this recipe, but you can also use a 9-inch springform pan if preferred. I prefer pans with non-stick coating or those made from high-quality carbon steel (like Nordic Ware). Grease the pan thoroughly with butter and flour or use a silicon baking mat to prevent sticking. For the water bath, choose a baking dish that’s at least 2 inches larger in diameter than your cake pan to ensure even heat distribution.

Mixing Bowls

Use a set of nested stainless steel mixing bowls—the 3-quart and 1-quart sizes work perfectly for this recipe. Stainless steel conducts heat evenly and won’t retain odors like plastic. For the egg whites, select a chilled bowl (place it in the freezer for 10 minutes before use) to help stabilize the meringue. A rubber spatula is also essential for gently folding dry ingredients into the egg whites without deflating them.

Oven Thermometer

Ovens can vary by 25°F or more, so an oven thermometer is a must for accurate baking. I use the Thermoworks Oven Thermometer—it’s reliable and easy to read. Place it in the center of the oven while preheating to 350°F and adjust your oven’s temperature if needed. This ensures your cake bakes evenly and avoids overbaking, which can dry out the delicate sponge. A wire rack is also helpful for cooling the cake completely after baking. 🌡️

Optional Extras

For a polished finish, consider a fine-mesh sieve to dust powdered sugar evenly over the cake and a sharp serrated knife for clean cuts. If you’re making multiple layers, a cake turntable makes frosting much easier. For storage, an airtight container with parchment paper between layers keeps the cake fresh for days. These extras aren’t mandatory but elevate the final presentation and texture.
