Chocolate Mousse Cake

Preheat the oven to 350 degrees F (175 degrees C). Prepare and bake cake mix according to package directions for two 9-inch layers. Cool and remove from pans.

In a large bowl, mix together sweetened condensed milk and melted chocolate. Gradually stir in water, then instant pudding until smooth. Chill for at least 30 minutes.

Remove chocolate mixture from the refrigerator and stir to loosen. Fold in whipped cream and return to the refrigerator for at least another hour.
