This is a perfect dessert for a crowd: creamy, chocolatey, incredibly rich, AND simple to make (really!). I found the recipe on epicurious.com (originally from Bon Appetit, Nov '92) several years ago. I've made it many times, and in the process have tweaked and tweaked, based on epicurious commenters' and my own experiences. The recipe below is my current version.
Chocolate Mousse Pie
28 Oreo cookies
1/3 cup unsalted butter, room temperature
1 1/2 cups semisweet chocolate chips
3 ounces unsweetened chocolate, chopped
pinch of salt
1 quart heavy whipping cream, divided
1/4 cup sugar
1 1/2 tsp vanilla
additional sugar and vanilla, to taste
chocolate shavings, optional
- Finely grind cookies in processor. Add butter and process until mixture is evenly moistened. Press crumb mixture onto bottom of a 10" springform pan. Bake at 350 degrees for about 8 minutes. Transfer to a rack and cool completely.
- Put chocolate and salt in a food processor. Bring 1 cup cream to a boil in the microwave. With the processor running, gradually pour hot cream through feed tube and process until chocolate is melted and smooth. Transfer mixture to a large bowl. Cool to room temperature, stirring occassionally.
- Beat 2 cups cream with sugar and vanilla until stiff peaks form. Fold into chocolate mixture. Spread over the prepared crust and chill until set, about 6 hours. (Can be prepared 1 day ahead.)
- Beat remaining cream (with a splash of vanilla and about 2 Tbsp sugar) to stiff peaks. Transfer to a pastry bag fitted with a star tip. Garnish top of cake with chocolate shavings, if desired, then pipe cream rosettes around the edge.

It may look like a disappointingly small piece, but because it is so rich, you'll be surprisingly satisfied.Yesterday I successfully experimented with preparing individual servings for a party. For the "crust" I put Oreos in the bottom of foil muffin papers, then topped them with the filling (yield=28 each). They were set in less than six hours, but are easier to eat today because the cookies have softened enough to be eaten with a spoon.
Storage and transportation in the muffin pan is a handy option:I topped the mini-mousses with whipped cream and a sprinkle of cocoa powder. Since I used a store bought "shaker top" instead of whipping my own cream, the rosettes deflated in mere minutes, much to my distress. Next time that's one shortcut I won't take!

NOVEMBER 2009 UPDATE:
I wanted to take this to a party with a substantial dessert spread and felt I needed even smaller servings than the muffin cups above. At a dessert buffet, noone wants to commit to a giant portion when there are so many treats to try.

Remembering a comment from the original online version, I baked the crust in a rectangular pan (about 10" x 15", the Pyrex that's bigger than a 9" x 13"). The crust and mousse were spread thin, but I think it was perfect. I was able to cut 48 pieces.
A squeeze of whipped cream and a sprinkling of cocoa, and the pan was ready to go.If thoroughly chilled (it's best made a day in advance but garnished just before departure), the portions are easy to serve, keeping their shape well. The low profile also meant that I could cover the pan with plastic wrap without disturbing the whipped cream. I used the real deal this time, and the rosettes looked fine even the next day.
