How to Make Tokyo Banana Cake Roll Recipe

To make Tokyo Banana Cake Roll, prepare a light sponge cake by whipping egg whites and folding them into a smooth egg yolk batter. Bake the cake in a thin layer, then roll it gently while warm to help it hold its shape. Prepare a creamy banana custard using milk, egg yolks, sugar, cornstarch, and mashed bananas. Once the cake and custard have cooled, spread the filling over the sponge, roll it carefully, and refrigerate until ready to slice.

Instructions to Make Tokyo Banana Cake Roll Recipe

1. Preheat your oven to 350°F (175°C). Line a 10 × 15-inch baking tray with parchment paper.
2. Separate the eggs, placing the whites in a clean mixing bowl and the yolks in another bowl.
3. Whisk the egg yolks with half of the sugar until pale and smooth. Add the milk, vegetable oil, and vanilla extract, then mix well.
4. Sift the flour and salt into the egg yolk mixture. Stir gently until a smooth batter forms.
5. Using an electric mixer, beat the egg whites until foamy. Gradually add the remaining sugar and continue beating until glossy, medium-stiff peaks form.
6. Fold one-third of the whipped egg whites into the yolk batter to lighten it. Gently fold in the remaining egg whites, taking care not to deflate the mixture.
7. Pour the batter into the prepared baking tray and spread it evenly. Bake for 10–14 minutes, or until the sponge springs back lightly when touched.
8. Remove the cake from the oven. Place a clean sheet of parchment paper over the cake and carefully turn it out. Peel away the baking paper from the bottom.
9. While the cake is still warm, gently roll it up with the parchment paper inside. Leave it rolled on a wire rack to cool.
10. To prepare the custard, mash the bananas until smooth. In a saucepan, whisk together the milk, sugar, egg yolks, and cornstarch until combined.
11. Heat the mixture over medium-low heat, stirring constantly, until it thickens into a smooth custard. Remove it from the heat and stir in the mashed bananas, vanilla extract, and butter.
12. Transfer the custard to a bowl. Cover the surface directly with plastic wrap to prevent a skin from forming, then refrigerate until completely cool.
13. Carefully unroll the cooled sponge cake. Spread the banana custard evenly over the surface, leaving a small border around the edges.
14. Roll the cake up gently again, using the parchment paper to guide it into a neat log. Avoid pressing too tightly, as the filling may squeeze out.
15. Wrap the cake roll and refrigerate for at least 1–2 hours to help the filling firm up.
16. Remove the parchment paper, trim the ends if desired, and slice the cake roll with a sharp knife. Sprinkle with powdered sugar or decorate before serving.

Tips for the Best Tokyo Banana Cake Roll Recipe

• Use ripe bananas for a naturally sweet and flavorful custard.
• Beat the egg whites in a clean, grease-free bowl for the best volume.
• Fold the egg whites gently into the batter to keep the sponge light and airy.
• Avoid overbaking the sponge because a dry cake can crack when rolled.
• Roll the cake while it is warm to help it develop its shape.
• Cool the custard completely before spreading it over the cake.
• Refrigerate the finished roll before slicing for cleaner pieces.
• Use a sharp knife and wipe it clean between cuts for a neat presentation.

Storage Instructions for Tokyo Banana Cake Roll Recipe

Store Tokyo Banana Cake Roll in an airtight container in the refrigerator for up to 3 days. Because the filling contains milk and eggs, keep the cake refrigerated and avoid leaving it at room temperature for more than 2 hours.

For the best texture, enjoy the cake within the first 1–2 days, when the sponge remains soft and the banana custard tastes fresh. Freezing is not recommended for the best custard texture, as the filling may become watery after thawing.
