Directions
Prepare
Sprinkle gelatin over cold water in a small cup and let stand 1 minute to soften.
Add boiling water and stir until gelatin is completely dissolved and mixture is clear.
Let the gelatin mixture cool while you mix the other ingredients.
Stir sugar and cocoa together in a medium bowl.
Chill a large bowl if possible.
Make the mousse
Mix whipping cream and vanilla on low speed.
Add the sugar and cocoa mixture.
Beat on medium speed, scraping the bottom occasionally, until the mixture forms soft peaks.
Pour in the gelatin mixture and beat until well blended and the mixture forms stiff peaks.
Serve
Spoon the mousse into serving dishes or a large bowl.
Refrigerate about 30 minutes before serving.
Garnish as desired.
Cover and refrigerate leftover desserts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Whipped into a foam that gives the mousse its light, airy structure.
- Unflavored gelatin
- Sets the whipped cream so the mousse holds its shape when chilled.
- Dutch processed cocoa powder
- Provides the chocolate flavor and color, and its low acidity gives a smooth taste.
- Powdered sugar
- Sweetens the mousse and dissolves smoothly into the cream.
The step that matters
Adding the gelatin mixture. Gelatin must be fully dissolved and cooled slightly before it goes in. Hot or lumpy gelatin can seize or form strings, and it sets unevenly in the cream.
