Preheat and Prepare the Pan
Preheat your oven to 350°F (175°C).
Line a 10x15-inch jelly roll pan with parchment paper and lightly grease it.
Make the Sponge Cake
In a large mixing bowl, beat the eggs and sugar together using an electric mixer on high speed until thick, pale, and fluffy (about 5 minutes).
Gently fold in the vanilla extract.
Sift the flour, baking powder, and salt together, then gradually fold them into the egg mixture using a spatula. Be careful not to deflate the batter.
Pour the batter into the prepared pan and spread evenly with an offset spatula. Bake for 10-12 minutes or until the top is springy to the touch.
Roll the Cake
While the cake is still warm, turn it out onto a clean kitchen towel generously dusted with powdered sugar.
Peel off the parchment paper and roll the cake tightly from the short end with the towel. Let it cool completely.
Prepare the Filling
In a bowl, beat the cream cheese, powdered sugar, and vanilla extract until smooth.
In a separate bowl, whip the heavy cream to stiff peaks. Gently fold the whipped cream into the cream cheese mixture until well combined.
Assemble the Cake Roll
Unroll the cooled cake and spread the filling evenly over the surface, leaving a small border. Sprinkle the diced strawberries over the filling.
Roll the cake back up tightly (without the towel) and place seam-side down on a serving platter.
Garnish and Chill
Spread whipped cream over the top of the roll and garnish with sliced strawberries. Refrigerate for at least 1 hour before serving to set.
