Ingredients
  

For the Cake
  • 4 large eggs Room temperature is best for proper mixing and aeration.
  • 1/2 cup granulated sugar Sweetness to balance the flavors.
  • 1/2 cup all-purpose flour Sifted for a light texture.
  • 1 teaspoon baking powder For added fluffiness.
  • 1/4 teaspoon salt Enhances the overall flavor.
  • 1/4 cup milk Use whole milk for richness; warm it slightly before adding.
  • 1 teaspoon vanilla extract Adds warmth and aroma to the cake.
For the Filling

  • 1 cup heavy cream For making the fluffy whipped cream filling.
  • 1/4 cup powdered sugar Sweetens the whipped cream without weighing it down.

Method
 

Preparation
  1. Preheat the Oven: Set your oven to 350°F (180°C) and line a 10×15-inch jelly roll pan with parchment paper.
  2. Make the Batter: In a large mixing bowl, beat the eggs and granulated sugar together until thick and pale in color—this should take about 5-7 minutes.
  3. Add Dry Ingredients: Sift in the flour, baking powder, and salt into the egg mixture. Gently fold it in with a spatula until just combined.
  4. Prepare the Milk Mixture: In a small saucepan, heat the milk until it’s warm but not boiling. Stir in the vanilla extract and gradually add to the batter, gently folding until smooth.
Baking
  1. Bake: Pour the batter into the prepared pan, spreading it evenly with a spatula. Bake for 12-15 minutes or until the cake is set and lightly golden brown.
  2. Prepare the Cooling Towel: Lay out a clean kitchen towel and sprinkle it with powdered sugar.
  3. Roll the Cake: Once the cake is done, loosen the edges, invert it onto the towel, and roll it from the short side with the towel inside. Let it cool on a wire rack.
Assembly
  1. Fill the Cake: Unroll the cooled cake gently and spread a layer of Japanese cotton candy evenly across the surface.
  2. Whip the Cream: In a separate bowl, whip the heavy cream with powdered sugar until stiff peaks form.
  3. Assemble the Roll: Spread the whipped cream over the cotton candy layer and roll the cake back up, gently removing the towel.
  4. Chill: Wrap the cake roll in plastic wrap and refrigerate for at least 2 hours to set.
  5. Serve: Slice the Japanese Cotton Candy Swiss Cake Roll into rounds and enjoy!

Notes

You can prepare the cake a day in advance. Store it wrapped tightly in the fridge until ready to serve. Keep leftovers in an airtight container for up to 3 days.
