01 - Preheat oven to 350°F. Line a 9x13-inch baking sheet with parchment paper and lightly grease with butter or cooking spray.
02 - Whisk together flour, granulated sugar, salt, and baking powder in a medium mixing bowl until well combined.
03 - In a separate bowl, beat eggs thoroughly, then add milk, melted butter, and vanilla extract. Whisk until uniform.
04 - Pour wet ingredients into dry ingredients. Stir 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 until stiff peaks form.
07 - Gently remove cooled cake from pan onto clean work surface. Trim edges evenly for clean appearance.
08 - Spread whipped cream in an even layer over cake surface, leaving a 1/2-inch border along one long edge. Distribute diced strawberries uniformly over cream.
09 - Starting from the opposite long edge, carefully roll cake tightly using parchment paper as a guide. Refrigerate rolled cake for 20 minutes to set.
10 - Remove from refrigerator and slice roll into 8 equal pieces. Top each piece with strawberry slice and fresh mint. Serve chilled.
