I use this chocolate mousse filling for pastries and other baked items that need to hold their shape. Cooled melted chocolate combined with whipped cream creates a chocolate mousse filling that can be used to fill or decorate cupcakes and other baked goods and layer cake slices without gelatin.

Try semi-sweet or bittersweet chocolate with 60%-72% cocoa solids. Microwave in 30-second intervals at 50% power, stirring between intervals, until melted. Let the chocolate cool to room temperature for 10-15 minutes. Hot chocolate will turn whipped cream into a soupy mixture.
The cream and mixing bowl need to be cold. Add powdered sugar and vanilla to the cream and beat until stiff peaks form. Don't overbeat the cream, it will have a gritty texture. Adding chopped chocolate to overbeaten cream will cause it to lose its airy texture.
I always use two bowls and a rubber spatula, even for small batches. Combine one-third of the whipped cream with the chocolate mixture, then fold in the rest of the whipped cream from the bottom of the bowl in large motions. Continue stirring until you no longer see any white streaks and the mousse is evenly colored.
