01 - Preheat oven to 350°F. Line a 9x13-inch baking sheet with parchment paper and lightly grease with butter or cooking spray.
02 - In a medium mixing bowl, whisk together flour, granulated sugar, salt, and baking powder until well blended.
03 - In a separate bowl, beat eggs with milk, melted butter, and vanilla extract until smooth. Pour wet mixture into dry ingredients and stir until just combined, being careful not to overmix.
04 - Spread batter evenly onto the prepared baking sheet. Bake for 12-15 minutes until the cake springs back when lightly touched. Allow to cool completely on a wire rack.
05 - While cake cools, whip heavy cream with powdered sugar and vanilla extract using an electric mixer or whisk until stiff peaks form.
06 - Carefully remove cooled cake from the pan and place on a clean, flat surface. Trim the edges for a neat appearance if desired.
07 - Spread whipped cream evenly over the entire cake surface, leaving a 1/2-inch border along one long side. Sprinkle diced strawberries uniformly over the cream layer.
08 - Starting from the long side opposite the border, tightly roll the cake using the parchment paper to guide and support the roll. Refrigerate for 20 minutes to set the shape.
09 - Remove from refrigerator and slice the rolled cake into 8 even pieces resembling sushi rolls. Top each piece with a strawberry slice and optional chopped mint. Serve chilled.
