8 tablespoons of unsalted butter, divided and very soft
3/4 cup of melted good quality dark chocolate
2 cups of heavy cream, very cold
1/2 teaspoon of dark rum
1/2 teaspoon of vanilla extract
- In a small microwaveable bowl, combine the chocolate and 4 tablespoons of butter. Melt in the microwave, 40 seconds at a time until the chocolate and butter are melted and smooth. Be careful when doing this as chocolate can burn quickly.
- Once melted, stir in the rum and vanilla and mix until smooth.
- Add about 1/2 cup of the cream to the chocolate mixture and stir to combine.
- In a larger cold mixing bowl, combine the remaining cream along with the chocolate cream mixture. Using a whisk or handheld mixer, whip the mixture to smooth but firm peaks. Be careful not to over whip as the mousse will break and have a grainy appearance. Cover the bowl with plastic wrap and set the mousse in the refrigerator to chill until ready to use.
