Instructions
Step 1: Prepare the Crust
Preheat oven to 350°F (175°C).
In a medium bowl, combine:
- Cookie crumbs
- Melted butter
- Sugar
Mix until evenly moistened.
Press firmly into the bottom and up the sides of a 9-inch pie plate.
Bake for 10 minutes.
Cool completely before filling.
Step 2: Melt the Chocolate
Place the chopped chocolate and butter in a heatproof bowl.
Melt over a pan of barely simmering water, stirring until smooth.
Remove from heat and allow to cool slightly.
Step 3: Prepare the Egg Yolks
Whisk the egg yolks with 2 tablespoons of sugar until lighter in color.
Slowly whisk the melted chocolate into the yolk mixture.
Add vanilla extract and mix until smooth.
Set aside.
Step 4: Whip the Cream
In a chilled mixing bowl, whip 2 cups heavy cream until soft peaks form.
Do not overwhip.
Refrigerate while preparing the egg whites.
Step 5: Beat the Egg Whites
In a clean bowl, beat:
- Egg whites
- Salt
until foamy.
Gradually add the remaining sugar.
Continue beating until glossy medium peaks form.
Step 6: Create the Mousse
Fold one-third of the whipped cream into the chocolate mixture to lighten it.
Gently fold in the remaining whipped cream.
Next, carefully fold in the beaten egg whites.
Use slow, gentle motions to maintain as much air as possible.
The mousse should be light, fluffy, and uniform in color.
Step 7: Fill the Pie
Spoon the mousse into the cooled crust.
Pile it high in the center to create the signature sky-high appearance.
Smooth or swirl the top decoratively with a spatula.
Step 8: Chill
Refrigerate for at least 6 hours, preferably overnight.
The mousse will firm up while remaining light and creamy.
