Ingredients You’ll Need
For the Cake:
-
4 large egg yolks
-
30 g (2 tbsp) granulated sugar
-
50 ml (3½ tbsp) whole milk
-
50 ml (3½ tbsp) neutral oil (canola or grapeseed)
-
½ tsp vanilla extract
-
60 g (½ cup) cake flour, sifted
-
Pinch of salt
For the Meringue:
-
4 large egg whites
-
¼ tsp cream of tartar
-
50 g (¼ cup) granulated sugar
For the Whipped Cream Filling:
-
1 cup heavy whipping cream (chilled)
-
2 tbsp powdered sugar
-
½ tsp vanilla extract
Step-by-Step Instructions
Step 1: Preheat & Prepare
Preheat your oven to 325°F (160°C). Line a 9×13-inch jelly roll pan with parchment paper, ensuring the paper extends up the sides to make it easier to lift the cake out later.
Step 2: Make the Yolk Batter
In a medium bowl, whisk the egg yolks and sugar until pale and slightly thickened. Stir in milk, oil, and vanilla extract until smooth. Sift in cake flour and salt. Mix gently until the batter is smooth with no visible flour streaks — avoid overmixing.
Step 3: Make the Meringue
In a separate, clean bowl, whip egg whites with cream of tartar on medium speed until foamy. Gradually add sugar while whipping until medium-stiff peaks form. The meringue should be glossy and hold a peak that bends slightly at the tip.
Step 4: Fold It All Together
Using a spatula, fold the meringue into the yolk batter in three additions. Work gently to keep as much air in the mixture as possible — this is the secret to a light, airy sponge.
Step 5: Bake the Cake
Pour the batter into the prepared pan. Smooth the surface and gently tap the pan on the counter to remove any large air bubbles. Bake for 20–25 minutes, or until the top is lightly golden and springs back when touched.
Step 6: Cool & Fill
Allow the cake to cool for a few minutes, then invert it onto a piece of parchment paper. Peel off the original baking paper. Cover with a clean tea towel and let cool completely. Meanwhile, whip the cream, powdered sugar, and vanilla until medium peaks form.
Step 7: Assemble & Roll
Spread the whipped cream evenly over the cooled cake. Starting from the short side, gently roll it up, using the parchment paper as a guide. Wrap the roll in parchment and chill for at least 1 hour before slicing.

Tips for Perfecting Your Japanese Swiss Roll
-
Use room-temperature eggs – This helps achieve maximum volume in your meringue.
-
Don’t over-whip the meringue – Medium-stiff peaks are ideal; over-whipping can cause dryness and cracking in the cake.
-
Roll while warm – Rolling the cake when it’s still slightly warm helps prevent cracks. You can do a “pre-roll” with parchment before adding cream, then unroll and fill.
-
Chill before slicing – Cooling in the fridge allows the cream to set, giving cleaner slices.
Variations to Try
-
Matcha Swiss Roll – Add 1–2 tsp matcha powder to the cake flour for a green tea twist.
-
Strawberry Cream Roll – Mix diced fresh strawberries into the whipped cream filling.
-
Chocolate Swiss Roll – Replace 15 g (about 2 tbsp) of cake flour with cocoa powder for a rich chocolate version.
-
Seasonal Fruit Topping – Decorate the top with powdered sugar and fresh berries for extra elegance.
How to Store Leftovers
-
Refrigerator: Wrap slices tightly in parchment or plastic wrap and store in an airtight container. It will stay fresh for 2–3 days.
-
Freezer: You can freeze the cake roll (unfilled or filled) for up to 1 month. Thaw overnight in the refrigerator before serving.

Frequently Asked Questions
Q: Can I make this cake without cream of tartar?
A: Yes, but cream of tartar helps stabilize the meringue. If you skip it, ensure your bowl is completely grease-free and whip the egg whites carefully.
Q: Why did my cake crack when rolling?
A: This often happens if the cake is too cool before rolling or if it’s overbaked. Try rolling it while still slightly warm or reducing bake time by 1–2 minutes.
Q: Can I make this cake gluten-free?
A: Yes, substitute cake flour with a gluten-free flour blend designed for baking. The texture may be slightly different, but still soft and airy.
Q: Can I prepare it the day before serving?
A: Absolutely! In fact, chilling overnight can enhance the flavor and make slicing easier.
