Chocolate Mousse Pie is a perfect summer dessert. It’s cold, light, gorgeous, and CHOCOLATE! What more could you want? My daughter called it Hobbit Pie because you’ll go there and back, again. I agree.
You can use milk, semi-sweet, or dark chocolate for the mousse and ganache, so Chocolate Mousse Pie is easily adaptable to any chocolate intensity preference. 🙂
Plus, it’s DELICIOUS!
Easy Step-By-Step Instructions for Chocolate Mousse Pie
While the crust is setting up, make the mousse filling as follows:

Combine
1 tablespoon hot water
¾ teaspoon unflavored gelatin powder
Mix to incorporate, then let dissolve for 5 minutes.

Pour over
6 ounces chopped chocolate (milk, semi-sweet, or dark depending upon how hard-core your chocolate tolerance is — I use semi-sweet)
Allow to stand for 10 minutes.

Heat in microwave for 60-90 seconds, until scalding but not boiling:
¾ cup heavy whipping cream
Pour over
9 ounces chocolate, chopped in pieces (semi-sweet or dark work best)
1 tablespoon butter
Allow to stand for 10 minutes.

… spread quickly as the cold mousse will make the ganache begin to set. Return to fridge for another hour.

Once the ganache has set, you can serve immediately, or cover the pie, and continue to refrigerate until you’re ready to eat it.
