Ingredients
Method
Prepare the Baking Pan:
- Preheat the oven to 350°F (175°C).
- Line a 15x10-inch jelly roll pan with parchment paper and lightly grease it.
Make the Cake Batter:
- In a large bowl, beat the eggs and granulated sugar on high speed for about 5 minutes until thick and pale.
- Stir in the vanilla extract.
Combine the Dry Ingredients:
- In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
- Gradually fold the dry ingredients into the egg mixture until just combined.
Incorporate the Liquids:
- In a small bowl, mix the milk and vegetable oil.
- Gently fold this into the batter until smooth and fully incorporated.
Create the Marbled Effect:
- Divide the batter into three equal portions and tint each with a different pastel food coloring (e.g., pink, blue, and yellow).
- Spoon dollops of the colored batter randomly onto the prepared pan.
- Use a toothpick or skewer to gently swirl the colors together for a marbled effect.
Bake the Cake:
- Bake for 10-12 minutes or until the cake springs back when lightly touched.
Roll the Cake:
- While the cake is still warm, carefully lift it with the parchment paper and place it on a clean surface.
- Dust a clean kitchen towel with powdered sugar and flip the cake onto the towel.
- Remove the parchment paper and gently roll the cake (with the towel inside) into a log shape.
- Let it cool completely.
Prepare the Whipped Cream Filling:
- In a chilled bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
Assemble the Swiss Roll:
- Carefully unroll the cooled cake.
- Spread the whipped cream evenly over the surface, leaving a small border around the edges.
- Re-roll the cake (without the towel), ensuring a tight but gentle roll.
Final Touches:
- Dust with powdered sugar for a simple finish.
- Slice and serve this beautifully marbled Swiss roll!
Notes
- Roll the cake while it's still warm to prevent cracks.
- Let the Jello cool slightly before pouring it over the cream cheese layer to prevent melting.
- Use gel food coloring for vibrant pastel shades without altering the batter consistency.
- Store leftovers in the refrigerator for up to 3 days.
