Avocado Sushi Cake Recipe: Matcha Green Velvet with Crunchy Rice Topping

This avocado sushi cake transforms a classic Japanese dessert into a vibrant, vegan masterpiece with layers of matcha-infused avocado mousse and crispy rice topping. 💚 The secret lies in using aquafaba to replace eggs, creating a silky texture that mimics traditional sushi cake while keeping it entirely plant-based. Every bite delivers the perfect contrast—creamy avocado, chewy rice, and delicate nori—without compromising on flavor or presentation.

The recipe begins with a matcha green velvet base, where ripe avocados blend with aquafaba and matcha powder to form a luscious, velvety layer. This isn’t just a dessert; it’s a textural experience, with each slice revealing the interplay of soft mousse and crispy rice. The addition of nori strips and cucumber ribbons elevates it beyond a simple cake, making it feel like a carefully crafted sushi roll in every bite.

What sets this apart is the crunchy rice topping, toasted to golden perfection and sprinkled with sesame seeds for an extra layer of texture. The assembly process is intuitive—layering the avocado mousse, pressing in the rice, and decorating with fresh ingredients—so even beginners can achieve restaurant-quality results. It’s elegant enough for special occasions but simple enough for a weeknight treat.

Perfect for vegan celebrations, brunch gatherings, or anyone craving a lighter yet indulgent dessert, this recipe proves that plant-based baking can be just as impressive as traditional methods. Let’s bring this vibrant, textured masterpiece to life.

Ingredients for avocado sushi cake

Vegan ingredients that deliver restaurant-quality texture and flavor in every layer.

Avocados are the foundation—ripe but firm with no brown spots. Local grocery stores or farmers markets often carry the best quality, especially in summer months. For matcha, Ippodo Tea or Jade Leaf are reliable brands that deliver consistent ceremonial-grade powder. Aquafaba is the secret binder here—save the liquid from two cans of chickpeas (like Banza or Eden Organic) and whisk until frothy. The Japanese short-grain rice should be sushi rice for optimal stickiness, though regular short-grain works in a pinch if you can't find specialty brands like Koshihikari.

No matcha? Double the amount of vanilla powder for a similar earthy note, though the color won't be as vibrant. Running out of aquafaba? Flax eggs (3 tbsp ground flax + 9 tbsp water) work as a 1:1 substitute, though texture may be slightly denser. For the rice topping, any short-grain rice will work, but don't skip the miso paste—it's what gives that authentic umami depth. The nori sheets should be high-quality, thin-cut (avoid the thick, brittle ones)—Marukyu brand is my go-to. Cucumber can be subbed with jicama or daikon radish if you're feeling adventurous, though the texture contrast won't be identical.

Avocados keep best when stored whole at room temperature for 1-2 days, then refrigerated. Once prepped, the mousse mixture stays fresh for up to 4 days in an airtight container with plastic wrap pressed directly on the surface. The cooked rice topping can be reheated in a dry pan for 2-3 minutes to restore crispiness. For make-ahead convenience, assemble the cake without the cucumber decorations—add those fresh just before serving. The entire cake keeps for 3 days in the fridge, though the texture may soften slightly. For longer storage, freeze the assembled cake (without toppings) for up to 2 months—thaw overnight in the fridge before serving.

Step-by-step instructions for avocado sushi cake

Transform ripe avocados into a luscious matcha-infused cake with a distinctive crunchy rice topping.

Halve the 4 whole ripe avocados and remove the pits. Scoop the flesh into a food processor and add the 0.5 cup matcha powder, 1 cup aquafaba, 0.5 cup granulated sugar, 2 tbsp lemon juice, and 1 tsp vanilla extract. Process until completely smooth, scraping down the sides as needed. The mixture should be vibrant green and light in texture—almost like a thick pudding.

I like to taste at this stage to ensure the matcha flavor is balanced. If it tastes too bitter, add a pinch more sugar. The avocado's natural oils will help emulsify everything beautifully, creating that signature velvety texture. Transfer the mixture to a mixing bowl and set aside.

Rinse the 2 cups Japanese short-grain rice under cold water until the water runs clear. In a small saucepan, heat the 1 tbsp vegetable oil over medium heat. Add the rice and toast it for 2-3 minutes, stirring constantly, until it becomes fragrant and slightly golden. This step is crucial—it develops the nutty flavor that makes this topping special.

Add 2 cups of water and the 1 tbsp white miso paste to the saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes. After 15 minutes, uncover and let the rice dry out completely in the pan—this creates that signature crunch. Once fully dry, spread the rice on a baking sheet and toast in a preheated 350°F oven for 10 minutes, stirring once halfway. The rice should be crispy and dry to the touch.

Line an 8x8-inch baking dish with parchment paper, leaving an overhang for easy removal. Spread half of the avocado matcha mixture evenly in the bottom of the dish. Place 4 of the nori sheets on top, slightly overlapping if needed to cover the surface completely. Repeat with the remaining matcha mixture and nori sheets.

For the rice topping, mix the toasted rice with the 2 tbsp sesame seeds. Sprinkle half of this mixture evenly over the top layer of nori. Fold the parchment overhang inward to create a neat package, then wrap tightly with plastic wrap. Chill in the refrigerator for at least 4 hours, or preferably overnight.

While the cake chills, prepare the cucumber glaze by julienning the peeled cucumber into thin strips. In a small bowl, whisk together the 1 tbsp agave nectar, 1 tbsp rice vinegar, and 0.5 tsp salt. Toss the cucumber strips in this mixture and let them marinate for 10 minutes.

When ready to serve, unwrap the cake and carefully slice into 8 equal pieces using a sharp knife. Arrange each piece on a plate and top with the marinated cucumber strips. The contrast between the creamy avocado layers, crispy rice topping, and refreshing cucumber glaze creates a perfect balance of textures and flavors.

Serving suggestions for this avocado sushi cake

Plating Like a Pro

Use a sharp 8-inch chef's knife to slice the cake cleanly into 8 equal rectangles—this ensures each serving has perfect proportions. Arrange slices on a white or light-colored plate to make the vibrant green matcha layers pop. I like to place a small dollop of coconut yogurt in the center of each plate before adding the cake slice for extra creaminess. 💚

Garnish Strategically

Sprinkle the marinated cucumber ribbons in a fan shape over the cake slice for visual appeal. Add toasted sesame seeds around the edges to frame the presentation. For an extra touch, place a single nori strip diagonally across the plate—this mimics traditional sushi presentation while keeping the dish cohesive. 🌟

Serve with Complements

Pair each slice with a small cup of chilled jasmine tea—its floral notes balance the earthy matcha. For a non-alcoholic option, serve sparkling yuzu soda (mix sparkling water with yuzu juice) to cut through the richness. I always include a mini bowl of pickled ginger on the side to refresh the palate between bites. ✨

Seasonal Adaptations

In summer, swap cucumber for thinly sliced mango tossed in lime juice. For fall, use pear slices with a cinnamon glaze instead. In winter, add crystallized ginger or dried persimmon for warmth. Each seasonal garnish keeps the dish exciting year-round. 🌿

Portion Control Tips

For individual servings, cut the cake into 12 smaller rectangles and serve with a mini scoop of coconut sorbet on the side. For large gatherings, assemble the cake in a 9x13-inch pan and slice into 16 pieces—this makes serving easier. Always let the cake sit at room temperature for 10 minutes before slicing to maintain texture. 🍽️

Make-Ahead Serving

Assemble the cake 1 day ahead and store it in an airtight container in the fridge. When ready to serve, let it sit at room temperature for 30 minutes before slicing. Reheat the cucumber glaze (if using) in the microwave for 10 seconds to restore freshness. This approach saves time while keeping the dessert restaurant-fresh. ⏰
