Slice the pound cake horizontally into thin, flat sheets.
Place a sheet of cake on a flat surface. Spread a thin layer of whipped cream or frosting.
Sprinkle diced strawberries evenly on top. Add a light drizzle of strawberry jam if desired.
Carefully roll the cake sheet into a log, gently pressing to keep it tight.
Roll the log in shredded coconut or crushed graham crackers for coating (optional).
Slice into 1-inch sushi-style pieces.
Drizzle with melted white chocolate for garnish.
