Whip the Cream:
In a medium bowl, beat the heavy cream with sugar and vanilla extract until soft peaks form. Chill in the fridge.
Prepare the Cake:
Lay the sponge cake flat on parchment paper and gently roll it with a rolling pin to make it flexible.
Layer the Fillings:
Spread a thin layer of strawberry jam or puree, then add the whipped cream evenly across the cake, leaving 1 inch of space at the edges.
Add Strawberries:
Evenly sprinkle chopped strawberries over the cream layer.
Roll It Up:
Using parchment paper for support, carefully roll the cake into a tight sushi-like log. Chill for 30–45 minutes to set.
Slice & Decorate:
Cut into 1-inch rolls. Top with whipped cream, strawberry slices, or drizzle with white chocolate for decoration.
