Chocolate Mousse Pie

Chocolate Mousse Pie! A crunchy Oreo cookie-crust is filled with light and luscious dark chocolate mousse. The pie is topped with a mountain of vanilla scented whipped cream and homemade chocolate curls.

Because we can’t have too many pies in the world, and because we can’t have too many chocolate desserts, I give you Chocolate Mousse Pie!

There are several steps to putting together this luscious treat. But most of the pie can be made well ahead of time. Believe me, it’s well worth the effort..

The curls will break into irregular pieces as you make them. You can see the piece on the left was made before the chocolate was set.

Helpful Hints for making Chocolate Mousse Pie:

  • It’s not absolutely necessary to bake the crust, but I like the toasted flavor and crunchy texture from a few minutes in the oven.
  • Once you start folding the chocolate base, cream and whipped egg whites together work quickly. You want to spread the mousse into the crust before the mousse sets.
  • To work ahead, the crust can be made several days in advance and kept, covered, at room temperature.
  • You can fill the crust with the mousse up to two days ahead. Once the mousse is set cover the pie with a sheet of plastic wrap to keep the surface from drying out. Add the whipped cream and chocolate curls the day you’re serving the pie.
  • When serving the pie, wipe the knife with a wet cloth between cuts for a clean slice.
  • If the crust is sticking to the pan, run the tip of a small spatula or knife between the crust and the pan to separate them.

  • Move the bowl to the mixer (or use a hand mixer) and whisk until the yolks are completely cooled and have lightened in color and texture. Whisk the melted chocolate into the yolk mixture in thirds. Fold the cream into the chocolate base.

  • To make chocolate curls spread the melted chocolate into a thin layer over a smooth surface like marble, granite or quartz. Allow the chocolate to barely set then use the edge of a bench scraper, spatula or knife to scrape the chocolate off the surface. It should form large flakes and curls as you scrape.
