I remember the first time I tried to make sushi rolls at home. It felt like a culinary final exam. I had sticky rice everywhere except on the nori, and my “rolls” looked more like sad, lumpy logs.
It was a mess. Delicious, but a mess. I thought there had to be an easier way to get those incredible sushi flavors without the intense pressure of perfect rolling.
That’s when I discovered the sushi cake. It’s all the goodness of a sushi roll—the seasoned rice, the fresh fish, the creamy avocado—but layered into a beautiful cake. It’s stunning, surprisingly simple, and a total crowd-pleaser. No rolling skills required.
What You’ll Need
Here are the ingredients that come together to create this masterpiece. I’ve broken them down by layer to make your shopping trip a breeze.
For the Sushi Rice:
- 2 cups uncooked short-grain sushi rice
- 2 cups water
- 1/2 cup rice vinegar
- 2 tablespoons granulated sugar
- 1 teaspoon salt
For the Spicy Salmon Layer:
- 1 lb sushi-grade salmon, finely diced
- 1/4 cup Japanese mayonnaise (like Kewpie)
- 2 tablespoons sriracha (or more, if you like heat)
- 1 tablespoon soy sauce
- 1 scallion, thinly sliced
For the Avocado Layer & Toppings:
- 2 large ripe avocados
- 1 tablespoon lime juice
- Toasted sesame seeds
- Furikake seasoning
- Extra sriracha and soy sauce for drizzling
- Pickled ginger and wasabi, for serving
Pro Tips for Success
I’ve made my fair share of these cakes, and I’ve picked up a few tricks. These tips will help you avoid the common pitfalls and get it right on your first try.
- Get the Rice Right: The foundation of your cake is the rice. Rinse it until the water runs clear to remove excess starch. Once cooked, let it cool to just above room temperature before mixing in the seasoned vinegar. Hot rice will get gummy, and cold rice won’t absorb the flavor well.
- Press Firmly, Not Fiercely: When you’re adding each layer into the pan, use the back of a wet spoon or a spatula to press down firmly and evenly. This compaction is what holds the cake together. Just don’t press so hard that you turn it into a dense brick.
- Avocado Management: To keep your avocado layer vibrant and green, mix it with lime juice immediately after mashing or slicing. Also, make it the very last component you prepare before assembling the final toppings to minimize air exposure.
- The Grand Unveiling: To release the cake from the springform pan, run a thin, wet knife around the inside edge first. This helps prevent sticking. Unlatch the spring slowly and lift it straight up. Voila!
Tools Required
You don’t need a professional kitchen, but a few specific tools will make this process much smoother.
- 8-inch springform pan
- Rice cooker or a medium saucepan with a lid
- Cutting board and sharp knife
- Mixing bowls
- Spatula or large spoon
Substitutions and Variations
One of the best things about this recipe is how adaptable it is. Feel free to get creative based on what you have or what you like.
| Original Ingredient | Substitution Idea | Notes |
|---|---|---|
| Sushi-Grade Salmon | Sushi-Grade Tuna | Creates a classic spicy tuna flavor. |
| Spicy Mayo | Plain Mayo + Chili Oil | Adjust chili oil to your heat preference. |
| Avocado | Thinly Sliced Cucumber | Adds a refreshing crunch. |
| Scallions | Chives or Red Onion | Finely dice the red onion. |
Add a Crunchy Layer: Mix some panko breadcrumbs or tempura bits into one of the layers for a fantastic textural contrast.
Go Vegetarian/Vegan: Swap the salmon for finely diced, seasoned, and baked tofu. You can also use a mix of edamame, cucumber, and shredded carrots. Use a vegan mayonnaise for a fully plant-based version.
Make-Ahead Tips
You can definitely prep some components in advance to make assembly quicker, which is perfect for a party.
The sushi rice can be cooked and seasoned a few hours ahead. Just keep it covered at room temperature. The spicy salmon mixture can also be prepared and kept in an airtight container in the fridge for up to 4 hours before you assemble.
Wait to slice the avocado and assemble the cake until just before you plan to serve it for maximum freshness.
How to Make the Avocado Layered Sushi Cake
Step 1: Cook the Sushi Rice
Rinse the sushi rice under cold water until the water runs clear. Cook the rice according to package directions or in your rice cooker. While it’s cooking, mix the rice vinegar, sugar, and salt in a small bowl until the sugar dissolves.
Step 2: Season the Rice
Once the rice is cooked, transfer it to a large, non-metallic bowl. Gently pour the vinegar mixture over the rice and use a rice paddle or spatula to “cut” and fold it in. Let the rice cool down for about 20-30 minutes.
Step 3: Prepare the Spicy Salmon
While the rice cools, dice your sushi-grade salmon into small, bite-sized pieces. In a separate bowl, combine the Japanese mayonnaise, sriracha, soy sauce, and sliced scallions. Add the diced salmon and gently mix until it’s fully coated.
Step 4: Assemble the First Layer
Lightly grease your 8-inch springform pan or line it with plastic wrap for easy removal. Take half of the cooled sushi rice and press it firmly and evenly into the bottom of the pan. A wet spoon helps prevent sticking.
Step 5: Add the Salmon Layer
Spread the spicy salmon mixture evenly over the first layer of rice. Gently press it down to compact it slightly.
Step 6: Add the Final Rice Layer
Add the remaining half of the sushi rice on top of the salmon. Press it down firmly to create a solid top layer. This is key to making sure your cake holds its shape.
Step 7: Chill and Prepare Toppings
Cover the pan with plastic wrap and refrigerate for at least 30 minutes, or up to 2 hours. This helps the cake set. Just before serving, mash or slice your avocados and mix with the lime juice.
Step 8: Decorate and Serve
Carefully run a knife around the edge of the pan and release the springform latch. Top the cake with the prepared avocado. Sprinkle generously with toasted sesame seeds and furikake. Drizzle with extra sriracha or soy sauce if you like. Serve immediately with pickled ginger and wasabi.
Nutrition, Diets, and Pairings
This cake is not only delicious but also packs a good nutritional punch.
Diet-Friendly Swaps
Making this fit your dietary needs is simple.
| For This Diet | Make This Change |

| Low-Carb | Use seasoned cauliflower rice (note: it won’t be as sticky). |
Meal Pairing Suggestions
This sushi cake is a meal on its own, but it pairs wonderfully with a few simple sides. Consider serving it with a warm bowl of miso soup, steamed edamame, or a simple seaweed salad. A crisp, dry white wine or a cold sake complements the flavors perfectly.
Time-Saving Tips
- Use a rice cooker for foolproof, hands-off rice cooking.
- Prepare the salmon mixture while the rice is cooking and cooling.
- Buy pre-toasted sesame seeds to save a step.
Leftovers and Storage
Sushi is always best enjoyed fresh, and this cake is no exception. If you do have leftovers, wrap the slice tightly in plastic wrap.
Store it in the refrigerator for up to one day. The texture of the rice will change as it gets colder and the avocado may brown slightly, but it will still be tasty. I do not recommend freezing this cake.
Frequently Asked Questions
Q1. My sushi cake fell apart when I removed the pan. What did I do wrong?
Ans: This usually happens for two reasons. Either the layers weren’t pressed down firmly enough during assembly, or the rice was too wet. Make sure to compact each layer well and follow the rice-to-water ratio closely.
Q2. Can I use regular long-grain white rice instead of sushi rice?
Ans: It’s not recommended. Short-grain sushi rice has a high starch content that makes it sticky, which is essential for holding the cake’s shape. Regular rice won’t bind together properly.
Q3. What does “sushi-grade” fish mean and where do I find it?
Ans: “Sushi-grade” or “sashimi-grade” means the fish is deemed safe for raw consumption. You can find it at reputable fish markets, Japanese grocery stores, or some high-end supermarkets. Always tell the fishmonger you plan to eat it raw.
Q4. How far in advance can I make the entire cake?
Ans: For the best texture and flavor, I suggest assembling it no more than 2-3 hours before serving. The longer it sits, the harder the rice will become and the more the avocado will brown.
