01 - Preheat oven to 350°F. Line a 9x13-inch baking sheet with parchment paper and lightly grease the surface.
02 - Whisk together flour, granulated sugar, salt, and baking powder in a mixing bowl until thoroughly incorporated.
03 - Beat eggs, milk, melted butter, and vanilla extract in a separate bowl until smooth.
04 - Pour wet ingredients into dry ingredients and stir until just combined. Avoid overmixing to prevent tough texture.
05 - Spread batter evenly onto prepared baking sheet. Bake for 12-15 minutes until cake springs back when touched lightly. Cool completely.
06 - Whip heavy cream with powdered sugar and vanilla extract until stiff peaks form. Refrigerate until ready to use.
07 - Remove cooled cake from pan and place on clean work surface. Trim edges for even rolling.
08 - Spread whipped cream evenly over cake surface, leaving 1/2-inch border along one long side. Distribute diced strawberries uniformly across cream layer.
09 - Starting from opposite long side, tightly roll cake using parchment paper as guide. Refrigerate for 20 minutes to set structure.
10 - Cut chilled roll into 8 equal pieces. Top each piece with strawberry slice and sprinkle with fresh mint. Serve chilled.
