Preheat the oven to 350°F (175°C) and line two 9-inch round cake pans with parchment paper.
In a large bowl, beat the eggs and sugar on high speed for about 8-10 minutes until pale and thick.
Gently fold in the sifted flour and baking powder, then add the vanilla and warm milk. Stir until combined.
Pour the batter evenly into the prepared pans and bake for 18-20 minutes or until a toothpick inserted comes out clean.
Let cakes cool in the pans for 10 minutes, then remove and cool completely on a wire rack.
Whip the heavy cream with powdered sugar until stiff peaks form.
Place one cake layer on a serving plate, spread with half the whipped cream, and top with half the sliced strawberries.
Add the second cake layer, spread the remaining cream on top, and finish with remaining strawberries.
Chill in the refrigerator for at least 1 hour before serving.
