01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - In a large mixing bowl, use an electric mixer to beat eggs, granulated sugar, and salt on high speed for 5 to 7 minutes until thick, pale, and tripled in volume.
03 - Gently fold in the all-purpose flour and one teaspoon of vanilla extract with a spatula, ensuring the batter remains airy.
04 - Divide the batter evenly into the prepared pans. Bake for 20 to 25 minutes or until cakes are golden and spring back when lightly pressed.
05 - Let cakes cool in pans for 10 minutes, then remove from pans and transfer to a wire rack to cool completely.
06 - In a chilled bowl, whip the heavy cream with powdered sugar and remaining vanilla extract until soft peaks form.
07 - If using, spread a thin layer of strawberry jam over one cake layer. Top with half of the whipped cream and half the sliced strawberries.
08 - Place second cake layer over strawberries. Spread remaining whipped cream over the top and decorate with the rest of the strawberries.
09 - Garnish with fresh mint leaves if desired. Refrigerate the cake for at least 30 minutes before slicing for best serving texture.
