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, beat eggs, granulated sugar, and salt with an electric mixer on high speed for 5 to 7 minutes until mixture is thick, pale, and has tripled in volume.
03 - Gently fold in all-purpose flour and vanilla extract using a spatula, taking care to maintain the batter’s volume.
04 - Divide the batter evenly between prepared pans and bake for 20 to 25 minutes until golden and cakes gently spring back to touch.
05 - Remove cakes from oven, allow to cool in pans for 10 minutes, then invert onto a wire rack to cool completely.
06 - While cakes cool, beat heavy cream, powdered sugar, and vanilla extract until soft peaks form.
07 - Optionally, spread a thin layer of strawberry jam over one cake layer. Spread half the whipped cream over this layer, then arrange half of the fresh strawberries on top.
08 - Place the second sponge layer over the strawberries. Spread remaining whipped cream over the top and finish by arranging the rest of the strawberries.
09 - Garnish with fresh mint leaves if desired. Refrigerate for at least 30 minutes before slicing for easier serving.
