It is SO good and SO easy. There are very few ingredients...it starts with a boxed cake mix for cryin' out loud! But it's still good enough to share with friends...if you must! I made it a couple years ago for a birthday (maybe mine?) and just made it tonight for my boss's surprise going-away potluck tomorrow. I think everyone at work will love it!
1 (18.25 ounce) package chocolate cake mix
1 (14 ounce) can sweetened condensed milk
2 (1 ounce) squares unsweetened chocolate, melted (it tells you on the box how to melt it best)
1/2 cup cold water
1 (3.9 ounce) package instant chocolate pudding mix
1 cup heavy cream, whipped (measure out 1/2 cup heavy cream, whip it with a hand mixer until thick)
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 the water, then instant pudding until smooth. Chill for at least 30 minutes.
Remove the chocolate mixture from the refrigerator, and stir to loosen. Fold in whipped cream and return to the refrigerator for at least another hour.
Place one layer of cake onto a serving plate. Top with 1 1/2 cups of the mousse, then cover with the remaining cake layer. Frost with the remaining mousse, and refrigerate until serving. Garnish with fresh fruit or chocolate shavings.
