Bean Curd Cake Recipe: Silky Mochi Texture With Sweet Bean Filling

This bean curd cake recipe delivers the perfect balance of silky mochi texture and sweet red bean filling—every bite is a harmonious blend of traditional Japanese craftsmanship and modern convenience. 💛 The secret lies in the precise ratio of gluten flour and sugar, which creates that signature chewy-yet-tender mouthfeel while maintaining a delicate, melt-in-your-mouth quality.

I've perfected this method through years of testing, ensuring the cake holds its shape beautifully whether you bake or steam it.

The foundation of this recipe begins with a smooth bean paste filling made from adzuki beans, which provides that classic sweetness without overpowering the delicate cake structure.

What makes this version special is the optional addition of matcha powder or black sesame seeds, which add layers of flavor complexity while keeping the preparation simple. The cake's exterior remains tender and slightly glossy, thanks to a light dusting of potato starch during the final setting stage.

By the time you're done, you'll have a restaurant-quality dessert that's elegant enough for special occasions but simple enough for everyday indulgence. The cake slices cleanly with a smooth finish, revealing that signature marbled pattern where the bean filling meets the mochi texture.

It's the kind of dessert that feels both nostalgic and innovative—perfect for impressing guests or treating yourself after a long week.

Whether you choose to bake or steam, this recipe delivers consistent results every time. The instructions include precise timing for both methods, along with tips for adjusting sweetness levels to your preference.

Serve it at room temperature for the best texture, or chill slightly for a more refined presentation. Here's how to create this beloved Japanese classic in your own kitchen.

Ingredients for bean curd cake

Twelve ingredients blend traditional Japanese craftsmanship with modern vegan simplicity—perfect for creating restaurant-quality mochi cake at home.

The gluten flour is non-negotiable—it's the secret to that signature chewy-yet-tender texture. Mochiko flour is available at Asian grocery stores like H Mart or online retailers such as Amazon. If you can't find it, King Arthur gluten flour works in a pinch, though the texture will be slightly different. The red bean paste should be smooth and sweet—Koyo brand is my go-to, but any high-quality anko will do. For extra depth, add the matcha powder or black sesame seeds to the batter before baking, but don't skip the potato starch—it's what gives the cake that signature glossy finish.

No aquafaba on hand? Whipped coconut cream works as a substitute, though it won't be as stable. The agave nectar is optional but adds a lovely caramel note—Madhava brand is my favorite, but any organic agave will do. If you're adjusting sweetness, start with half the amount and taste as you go. The vegetable oil should be neutral-flavored—Avocado Brand or Mazola are great choices. For a more refined presentation, dust the finished cake with a little extra potato starch before slicing. And if you're feeling adventurous, swap half the red bean paste for black sesame paste—it adds a rich, nutty contrast.

This cake keeps beautifully—3 days at room temperature wrapped in plastic, or 1 week in the fridge. For longer storage, slice and freeze between parchment paper for up to 3 months. The texture actually improves after a day or two as the flavors meld. To serve, dust with potato starch again and slice with a hot, damp knife for clean cuts. Store leftovers in an airtight container with a slice of bread to absorb moisture—trust me, it makes all the difference.

Step-by-step instructions for bean curd cake

Here's how to create that perfect chewy-yet-silky texture with sweet adzuki filling!

In a clean, grease-free mixing bowl, combine the 0.5 cup Aquafaba and 1 tbsp Agave Nectar. Using a hand mixer or stand mixer with the whisk attachment, beat on medium-high speed for 3-5 minutes until the mixture forms stiff peaks that hold their shape when the whisk is lifted. You'll know it's ready when the aquafaba looks glossy and holds its shape like whipped cream.

I like to add the agave nectar gradually during the last minute of whipping to stabilize the mixture. If you're using the optional 1 tbsp Matcha Powder, sift it in during the final 30 seconds of whipping to distribute it evenly. The matcha will give your cake a beautiful green hue and earthy flavor that pairs perfectly with the sweet bean filling.

In a separate large bowl, sift together the 2 cups Gluten Flour, 1.5 cups Granulated Sugar, and 1 tbsp Cornstarch. This sifting step is crucial—it prevents lumps and ensures your cake has that signature silky texture. Use a whisk to break up any remaining clumps and create a fine, powdery mixture.

Next, make a well in the center of the dry ingredients and gently fold in the whipped aquafaba mixture. Be careful not to deflate the whipped peaks—use a spatula to gently fold from the bottom up until just combined. The batter should be thick and glossy, with no visible streaks of flour. If it's too stiff to fold easily, add 1-2 tablespoons of the 0.25 cup Water to loosen it slightly.

Scoop 1 cup of the red bean paste (Anko) into a small microwave-safe bowl. Microwave it for 20-30 seconds to soften slightly—this makes it easier to work with and ensures even distribution in your cake. The paste should be warm but not runny; if it's too thick, add a tiny splash of water to loosen it just enough to pipe smoothly.

Transfer the softened bean paste to a piping bag fitted with a small round tip (about ½-inch diameter). This will give you those beautiful, even dollops of filling that create that signature marbled look. Keep the remaining 0.5 cup Red Bean Paste (Anko) in the fridge for later—you'll need it to fill the center of each cake piece.

Lightly grease a 6-inch round cake pan with the 2 tbsp Vegetable Oil and dust it thoroughly with 0.25 cup Potato Starch, tapping out any excess. This prevents sticking and gives your cake that beautiful golden crust. Divide the batter evenly between the pan, creating two thin layers about ¼-inch thick each.

Place the pan in a steamer basket over 1 inch of boiling water. Cover with a tight lid and steam on medium-high heat for 12-15 minutes, until the edges pull away from the pan and the top looks slightly dry to the touch. The cake should spring back when gently pressed—this indicates it's cooked through but still moist. Let it cool in the pan for 5 minutes before removing.

Once the cake layers have cooled slightly, carefully remove them from the pan and place them on a clean work surface dusted with potato starch. Use a 2-inch round cutter to cut each layer into 6 equal pieces (you should have 12 total pieces). For the filling, pipe a small dollop of the bean paste onto the bottom of each cake piece, then place another piece on top to create a sandwich.

For the final touch, sprinkle the 2 tbsp Black Sesame Seeds evenly over each cake piece. These seeds add a beautiful contrast in color and a nutty crunch that complements the soft, chewy texture of the cake. Serve immediately while still warm for the best texture, or store in an airtight container in the fridge for up to 3 days. The flavors actually improve as they sit!

Sweet & Savory Fillings

Swap the classic red bean paste for black sesame paste (about 1.5 cups) for a nutty, earthy twist that pairs beautifully with the mochi texture. I like to mix ½ cup black sesame paste with ½ cup sweetened coconut flakes to create a tropical-inspired variation.
