01 - Preheat oven to 350°F. Line a 9x13-inch baking sheet with parchment paper and lightly grease with cooking spray or butter.
02 - In a medium bowl, whisk together flour, granulated sugar, salt, and baking powder until well combined.
03 - In a separate bowl, beat eggs with milk, melted butter, and vanilla extract until smooth.
04 - Pour wet ingredients into dry ingredients. Fold gently with a spatula until just combined, being careful not to overmix.
05 - Spread batter evenly onto prepared baking sheet. Bake for 12-15 minutes until cake springs back when lightly touched. Cool completely on wire rack.
06 - While cake cools, whip heavy cream with powdered sugar and vanilla extract using electric mixer or whisk until stiff peaks form.
07 - Gently remove cooled cake from pan. Place on clean work surface and trim edges with sharp knife for neat presentation.
08 - Spread whipped cream evenly over cake surface, leaving 1/2-inch border along one long edge. Sprinkle diced strawberries across cream layer.
09 - Starting from opposite long side, carefully roll cake tightly. Use parchment paper to guide and support the roll. Wrap and refrigerate 20 minutes to set.
10 - Remove from refrigerator and slice roll into 8 equal pieces. Top each piece with fresh strawberry slice and mint sprinkle. Serve chilled.
