Cake:
1 cup all-purpose flour
1 1/2 teaspoons baking powder
1/4 teaspoon salt
5 large eggs, separated
1 cup sugar
1/3 cup milk
1 teaspoon vanilla extract
Tres Leches Mixture:
1/4 cup heavy cream
One 14-ounce can sweetened condensed milk
One 12-ounce can evaporated milk
1 teaspoon vanilla extract
Icing:
1 pint heavy cream, for whipping
3 tablespoons sugar
Strawberries and blueberries to decorate
For the cake: Preheat the oven to 350 degrees. Grease and flour a 9- by 13-inch cake pan.
Sift the flour, baking powder and salt into a large bowl.
Separate the eggs. Beat the egg yolks with 3/4 cup of the sugar on high speed until the yolks are pale yellow. Stir in the milk and vanilla. Pour the egg yolk mixture over the flour mixture and stir very gently until combined.
Beat the egg whites on high speed until soft peaks form. With the mixer on, pour in the remaining 1/4 cup sugar and beat until the egg whites are stiff but not dry. Fold the egg white mixture into the batter very gently until just combined. Spoon into the prepared pan and spread to even out the surface.
Bake until the cake is done, 35 to 40 minutes. Allow to cool in the pan.
For the tres leches: Combine the heavy cream, evaporated milk, condensed milk and vanilla in a small pitcher. Pierce the surface of the cake with a fork several times. Drizzle the milk mixture over the top and allow the cake to sit and absorb the milk mixture. Don't worry about totally soaking the cake! That's what you want.
For the icing: Whip the cream with the sugar. Spread it evenly over the top and sides of the soaked cake and decorate with strawberries and blueberries or fruit of your choice.
Refrigerate until ready to serve.
Enjoy!
