3 Milk Cake or Tres Leches

1. Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9x13-inch baking pan. 2. Beat egg whites in a large glass, metal, or ceramic bowl with an electric mixer until fluffy; gradually beat in sugar until soft peaks form. Gradually beat in flour, then beat in milk, egg yolks, melted butter, 4 teaspoons vanilla extract, and baking powder, thoroughly beating in each ingredient before adding the next. Pour batter into the prepared baking pan. 3. Bake in the preheated oven until browned and crusty on top, no more than 30 minutes. Cool cake in the pan for 10 minutes; gently remove from the pan to finish cooling. 4. Whisk sweetened condensed milk, evaporated milk, and half-and-half together in a bowl; pour half into a pan deeper and longer than cake. Lay cooled cake in milk mixture; score deep lines in cake top using a fork. Pour remaining milk mixture over cake, allowing mixture to soak in. 5. Beat cream cheese and remaining 1 teaspoon vanilla extract in a bowl with an electric mixer until soft and fluffy; gradually beat in heavy cream until frosting is thick and spreadable. Spread over cake.
