Preheat oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan.
In a medium bowl, whisk together flour, baking powder, and salt.
Separate eggs. In a large bowl, beat egg yolks with ¾ cup sugar until pale yellow. Stir in milk and vanilla.
Pour egg yolk mixture over flour mixture and stir gently until combined.
In a separate bowl, beat egg whites on high speed until soft peaks form. Gradually add remaining ¼ cup sugar and beat until stiff peaks form.
Fold egg white mixture into batter gently until just combined. Pour batter into prepared pan.
Bake for 30 minutes or until a toothpick comes out clean. Let cake cool completely.
In a small bowl, whisk together evaporated milk, sweetened condensed milk, and ¼ cup heavy cream. Pour over cooled cake.
In a large bowl, beat 1 ½ cups heavy whipping cream with powdered sugar until stiff peaks form. Spread over cake.
