There are some varieties out there, a bit of variation, but it's basically a chocolate pudding pie. You've got chocolate pudding, crumbled up Oreos, whipped cream, chocolate fudge sauce. Frozen ones have chocolate ice cream instead of chocolate pudding. You can make them in pie pans or you can put them in smaller pie pans or jars or cups. If you add gummi worms, it's a mud pie with worms.
