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 medium bowl until thoroughly combined.
03 - Beat eggs, milk, melted butter, and vanilla extract in a separate bowl until homogeneous.
04 - Pour wet ingredients into dry ingredients. Mix gently 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.
06 - While cake cools, whip heavy cream with powdered sugar and vanilla extract until stiff peaks form.
07 - Remove cooled cake from pan and place on clean surface. Trim edges for a neat appearance.
08 - Spread whipped cream evenly over cake surface, leaving a 1/2-inch border along one long side. Sprinkle diced strawberries over cream layer.
09 - Starting from the opposite long side, roll cake tightly using parchment paper to guide the roll. Refrigerate for 20 minutes to set.
10 - Slice rolled cake into 8 even pieces. Top each piece with a strawberry slice and sprinkle with chopped mint if desired. Serve chilled.
