01 - Preheat oven to 350°F (180°C). Grease and line two 8-inch round cake pans with parchment paper.
02 - In a large mixing bowl, combine eggs, granulated sugar, and salt. Beat with an electric mixer on high speed for 5–7 minutes until the mixture is thick, pale, and has tripled in volume.
03 - Gently fold in flour and vanilla extract with a spatula, taking care not to deflate the airy batter.
04 - Evenly divide the batter between the prepared pans. Bake for 20–25 minutes until golden and cakes spring back when lightly pressed.
05 - Let cakes cool in pans for 10 minutes before turning out onto a wire rack to cool completely.
06 - While the cakes cool, whip heavy cream, powdered sugar, and vanilla extract together until soft peaks form.
07 - If desired, spread a thin layer of strawberry jam over one cooled cake layer for extra flavor.
08 - Spread half of the whipped cream onto the base cake layer and arrange half the sliced strawberries over the cream. Place the second sponge layer on top.
09 - Spread the remaining whipped cream over the top, arrange remaining strawberries, and garnish with fresh mint leaves if desired.
10 - Refrigerate assembled cake for at least 30 minutes before slicing to ensure clean, neat portions.
