Tres Leches Cake

Make the cake: Preheat the oven to 350 degrees F (175 degrees C). Spray a 9-inch springform pan with floured cooking spray.

Beat 3/4 cup sugar and egg yolks in a mixing bowl with an electric mixer until light in color and doubled in volume. Stir in flour, milk, baking powder, and vanilla.

Beat egg whites in a glass or metal bowl until soft peaks form. Gradually add remaining 1/4 cup sugar, continuing to beat until medium peaks form. Fold 1/3 of the egg white mixture into the egg yolk mixture to lighten it. Fold in remaining egg whites, then pour batter into the prepared pan.
