This recipe by far my go to when pleasing a crowd. You can serve in glasses like I did here or in a trifle bowl. When there's an event I'm invited to, the host/hostess always asks me to bring this along.
1 Chocolate cake mix (or your own) prepared
1/3 cup Kahlua liqueur (or sweetened black coffee)
3 pkgs Instant chocolate pudding
1 1/2 cups skor or heath chocolate (I always use Skor)
4 cups Sweetened Whipped Cream
Make holes, using a fork, all over top of the baked cake. Drizzle the Kahlua over top. Let stand 10 minutes. Chop the cake into small pieces.
Layer the pudding
Add the chocolate bits
Then the whipped cream and repeat.
