Preheat the oven to 350°F (175°C).
Grease and flour a 9x13 inch baking pan.
In a mixing bowl, combine the cake mix, eggs, and water. Beat on medium speed for 2 minutes until well blended.
Pour the batter into the prepared pan.
Bake for 30 minutes or until a toothpick inserted comes out clean.
Allow the cake to cool in the pan for 10 minutes.
Poke holes into the cooled cake using a skewer or fork.
In a bowl, mix the sweetened condensed milk and puree.
Pour the mixture over the holes in the cake, allowing it to soak in.
Top with whipped cream and fresh berries before serving.
