Ingredients You’ll Need
Before we dive into the steps, let’s gather everything you’ll need. Here’s a list of ingredients for the cake and the filling:
For the Cake:
- 4 large eggs
- 100g (1/2 cup) granulated sugar
- 60g (1/2 cup) all-purpose flour
- 20g (1/4 cup) cocoa powder
- 1 tsp baking powder
- 1/4 tsp salt
- 2 tbsp milk
- 2 tbsp vegetable oil
- 1 tsp vanilla extract

For the Filling:
- 200ml (3/4 cup) heavy cream
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
- 100g (1/2 cup) dark chocolate, melted and cooled
Step-by-Step Instructions
Now that you have all your ingredients ready, let’s get baking!
Step 1: Preheat and Prepare
Preheat your oven to 175°C (350°F). Line a 10×15 inch (25×38 cm) baking sheet with parchment paper. Lightly grease the paper to prevent the cake from sticking.
Step 2: Whip the Eggs
In a large mixing bowl, beat the eggs using an electric mixer at high speed until they become thick and pale yellow. This usually takes about 5 minutes. Gradually add the granulated sugar, continuing to beat until the mixture is fluffy.
Step 3: Sift Dry Ingredients
In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Sifting helps to incorporate air, ensuring a light and airy cake.
Step 4: Combine Wet and Dry Ingredients

Gently fold the dry ingredients into the egg mixture, being careful not to deflate the batter. Add the milk, vegetable oil, and vanilla extract, folding until just combined.
Step 5: Bake the Cake
Pour the batter into the prepared baking sheet, spreading it evenly. Bake for 10-12 minutes, or until the top of the cake springs back when lightly touched. Avoid overbaking, as this will make the cake dry and difficult to roll.
Step 6: Roll the Cake
While the cake is still warm, place a clean kitchen towel over the top and carefully flip the cake onto the towel. Peel off the parchment paper. Starting from one short end, roll the cake up with the towel inside. This step helps to shape the cake and prevent cracking. Allow it to cool completely.
Step 7: Prepare the Filling
While the cake cools, prepare the filling. In a chilled mixing bowl, beat the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Gently fold in the melted chocolate until well combined.
Step 8: Assemble the Cake

Unroll the cooled cake and spread the chocolate cream filling evenly over the surface. Roll the cake back up, this time without the towel. Wrap the rolled cake in plastic wrap and refrigerate for at least 1 hour to set.
Serving Suggestions
Once your Japanese Chocolate Roll Cake is set, it’s ready to be served. Here are a few serving suggestions to elevate your dessert experience:
- Dust with powdered sugar: A light dusting of powdered sugar adds a touch of elegance.
- Top with fresh berries: Strawberries, raspberries, or blueberries add a burst of freshness.
- Drizzle with chocolate sauce: For an extra indulgent treat, drizzle some chocolate sauce over each slice.
- Serve with ice cream: A scoop of vanilla or chocolate ice cream pairs perfectly with this cake.
Tips for Success
To ensure your Japanese Chocolate Roll Cake turns out perfectly every time, keep these tips in mind:
- Use room temperature eggs: Room temperature eggs whip up better and create more volume.
- Don’t overmix the batter: Overmixing can deflate the batter, resulting in a dense cake.
- Roll the cake while warm: Rolling the cake while it’s warm helps prevent cracks.
- Chill the filling bowl: Chilling the bowl and beaters before whipping the cream helps achieve stiff peaks.
