These whimsical treats combine fluffy sponge cake with sweet whipped cream and fresh strawberries, rolled together and sliced into adorable sushi-inspired pieces. The process involves baking a thin sponge, letting it cool, then filling it with a light strawberry cream before rolling and slicing. Optional coconut on the edges mimics rice, while fresh strawberry slices add the perfect finishing touch.
I stumbled across this idea while meal prepping regular sushi one Sunday afternoon and somehow my brain wired together sweet and savory. My roommate walked in mid assembly and stared at the coconut coated cake rolls like I had completely lost my mind. Now it is the one dessert that actually makes people pause Instagram stories to ask what on earth they are looking at. The best part is watching guests realize they are eating cake disguised as something entirely different.
I made these for a dinner party where someone casually mentioned they loved sushi and I decided to take them literally. The table went quiet when I served the platter but erupted into laughter after the first bite. Now my friends request them by name and nobody believes how simple the process actually is until they try rolling one themselves.
Ingredients
- 100 g all purpose flour: Sift this twice to prevent any lumps in your delicate sponge cake layer
- 100 g granulated sugar: This quantity sweetens the cake perfectly without overwhelming the fresh fruit
- 3 large eggs: Room temperature eggs whip up much higher and create that airy texture we need
- 1/2 tsp vanilla extract: Pure vanilla makes all the difference here since it is a star flavor
- 1/4 tsp salt: A tiny pinch balances the sweetness and makes all flavors pop
- 180 ml heavy whipping cream: Cold cream whips faster and holds its shape better through rolling
- 1 tbsp powdered sugar: Just enough to stabilize the cream without making it too sweet
- 1/2 tsp vanilla extract: Reinforces that vanilla note throughout the cream filling
- 100 g fresh strawberries: Pick berries that are slightly firm so they do not turn the cream watery
- 1 2 tbsp desiccated coconut: This mimics the rice on actual sushi rolls perfectly
Instructions
- Prep your oven and pan:
- Preheat to 180°C and line a 23 x 33 cm baking sheet with parchment paper making sure to crease the corners well
- Whip the eggs and sugar:
- Beat on high speed for about 5 minutes until the mixture is pale thick and leaves a ribbon when you lift the beaters
- Fold in the dry ingredients:
- Sift in the flour and salt then gently fold with a spatula being careful not to deflate all that air you just whipped in
- Bake the sponge:
- Spread the batter evenly and bake for 12 15 minutes until the top springs back when touched lightly
- Roll while warm:
- Turn onto a sugar dusted towel peel off the parchment and roll from the short end letting it cool completely wrapped in the towel
- Make the strawberry cream:
- Whip the cream with powdered sugar and vanilla to stiff peaks then fold in the diced strawberries gently
- Fill the cake:
- Unroll the cooled sponge spread the cream evenly leaving a small border then roll it back up tightly without the towel
- Slice and finish:
- Trim the ends for neatness then slice into 2 cm rounds and roll the edges in coconut to complete the sushi look
My niece helped me make these last summer and she took such pride in explaining the sushi cake concept to everyone at the picnic. Something about the tiny portion sizes and the whimsical presentation makes even the most serious adults smile. These have become my go to when I need to bring something that starts a conversation.
Making It Your Own
The beauty of this concept is how easily it adapts to whatever berries are in season or whatever flavors you are craving. I have swapped strawberries for diced mango and lime cream in the summer and used spiced apple in the fall. The coconut rice effect works with almost any flavor combination you can dream up.
Getting The Perfect Roll
The towel rolling technique might feel strange if you have never made a jelly roll before but it is absolutely essential for success. Take your time spreading the batter evenly because thin spots will tear and thick spots will make rolling difficult. A gentle touch when folding in the strawberries keeps the cream looking fresh rather than turning it pink immediately.
Serving Suggestions
Arrange these on a long platter with pickled ginger and little wasabi blobs made from tinted cream cheese for the full sushi restaurant effect. They disappear quickly so I always make extra and keep a secret stash in the back of the fridge. The coconut adds such a perfect textural contrast that I almost never skip it even when I am tempted to save time.
- Chill your knife between slices for the cleanest edges
- These are best served the same day but will keep overnight in the fridge
- Leftover unfilled sponge freezes beautifully for future projects
Every time I serve these I am reminded that the best desserts are the ones that make people laugh before they even take a bite. Hope these bring as much joy to your table as they have to mine.
Recipe Questions & Answers
- → How long do these rolls stay fresh?
-
These are best enjoyed the same day they're made, as the sponge can become soggy over time. Store in an airtight container in the refrigerator for up to 24 hours.
- → Can I make the sponge ahead of time?
-
Yes, you can bake the sponge cake up to one day in advance. Wrap it tightly in plastic wrap once cooled and store at room temperature until ready to fill and roll.
- → What other fruits work well in this filling?
-
Diced mangoes, blueberries, raspberries, or peaches make excellent alternatives to strawberries. You can also mix multiple berries for a colorful variation.
- → Why does my sponge crack when rolling?
-
Cracking usually happens when the sponge is rolled while too warm or overbaked. Let it cool completely in the towel before unrolling, and avoid overbaking which dries out the cake.
- → Can I freeze these rolled treats?
-
Freezing isn't recommended as the texture of both sponge and cream will change. For best results, assemble and serve fresh on the same day.
- → What's the purpose of the kitchen towel?
-
The towel helps create a tight roll without cracking the warm sponge. Rolling it while still warm (but not hot) trains the cake to hold its cylindrical shape once filled.
