How to prepare Japanese Banana Swiss Roll Cake

Ingredients:

• 🥚 4 large eggs (room temperature)
• 🥄 80 g (2⁄3 cup) cake flour (or all-purpose flour, sifted 2x)
• 🥄 80 g (2⁄5 cup) granulated sugar
• 🥄 2 tbsp vegetable oil (neutral flavor like canola or sunflower)
• 🥛 2 tbsp milk
• 🍦 1 tsp vanilla extract (optional)
• 🍋 1⁄2 tsp lemon juice or white vinegar (for egg whites)
• 🧂 Pinch of salt
• 🍶 200 ml (3⁄4 cup + 1 tbsp) heavy whipping cream (cold)
• 🍬 1–2 tbsp powdered sugar (to taste)
• 🍌 1 whole ripe banana (peeled)

Instructions:

1. Preheat your oven to 180°C (350°F). Line a 30×30 cm (12×12 inch) baking pan with parchment paper.
2. Separate the egg whites and yolks. In a bowl, whisk the egg yolks with granulated sugar until the mixture is pale and creamy.
3. Add vegetable oil, milk, and vanilla extract to the yolk mixture, and blend until smooth.
4. Sift in the flour and mix until just combined. Set aside.
5. In another clean bowl, beat the egg whites with lemon juice (or vinegar) and a pinch of salt until soft peaks form.
6. Slowly add the remaining sugar, and continue to whip until you achieve stiff peaks.
7. Carefully fold the egg whites into the yolk mixture in three parts. Make sure not to deflate the batter.
8. Pour the batter into the prepared pan and spread it out evenly.
9. Bake in the preheated oven for about 12-15 minutes, or until lightly golden and springs back when touched.
10. Remove from the oven and allow it to cool for a few minutes before transferring it onto a clean kitchen towel dusted with powdered sugar.
11. Peel off the parchment paper and using the towel, gently roll the cake up. Let it cool completely.
12. In a chilled bowl, whip the heavy cream along with powdered sugar until soft peaks form.
13. Unroll the cooled cake, spread the whipped cream evenly, and place the banana in a straight line down the center.
14. Roll the cake back up gently, making sure to keep it tight but not too tight to squish the filling.
15. Wrap in plastic wrap and refrigerate for at least 1 hour before slicing.
