01 - Preheat oven to 350°F. Line a 9x13-inch baking sheet with parchment paper and lightly grease.
02 - Whisk together flour, sugar, salt, and baking powder in a mixing bowl.
03 - Beat eggs, milk, melted butter, and vanilla extract in a separate bowl until well combined.
04 - Pour wet ingredients into dry ingredients and mix until just combined. Do not overmix.
05 - Spread batter evenly onto the prepared baking sheet. Bake for 12-15 minutes until cake springs back when touched. Cool completely.
06 - Whip heavy cream with powdered sugar and vanilla extract until stiff peaks form while cake cools.
07 - Gently remove cooled cake from the pan and place on a clean surface. Trim edges for neatness.
08 - Spread whipped cream evenly over the cake, leaving a 1/2-inch border along one long side. Sprinkle diced strawberries over the cream.
09 - Starting from the opposite long side, tightly roll the cake using parchment paper to guide the roll. Refrigerate for 20 minutes to set.
10 - Slice the rolled cake into 8 even pieces to resemble sushi rolls. Top each piece with a strawberry slice and chopped mint if desired. Serve chilled.
