01 - Preheat the oven to 350°F (180°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
02 - In a large mixing bowl, combine eggs, granulated sugar, and salt. Using an electric mixer on high speed, beat for 5 to 7 minutes until the mixture becomes thick, pale, and triples in volume.
03 - Gently fold in the all-purpose flour and vanilla extract using a spatula, taking care not to deflate the batter.
04 - Divide the batter evenly between the two prepared cake pans. Bake for 20 to 25 minutes, or until the cakes are golden and spring back when pressed lightly.
05 - Remove the cakes from the oven and let them cool in their pans for 10 minutes. Turn out onto a wire rack and allow them to cool completely.
06 - While cakes are cooling, whip heavy cream, powdered sugar, and vanilla extract together in a cold bowl 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 over the base cake layer. Arrange half of the sliced strawberries on top.
09 - Place the second cake layer over the strawberries. Spread the remaining cream on top and decorate with the rest of the strawberries.
10 - Garnish with fresh mint leaves if desired. Chill the assembled cake for at least 30 minutes before slicing for best results.
