What is the best recipe for a tuxedo mousse cake?
I'm trying to make a tuxedo mousse cake for a special occasion. Do you have a recipe for that?
Yes, I do. Here is the recipe: 

Ingredients:
- 1 1/2 cups heavy cream
- 8 ounces semisweet chocolate, chopped
- 4 ounces bittersweet chocolate, chopped
- 4 large eggs, separated
- 1/4 cup granulated sugar
- 1/4 teaspoon cream of tartar
- 1 tablespoon vanilla extract

Instructions:
1. In a double boiler or microwave, melt the chocolates together until smooth. Allow to cool to room temperature.
2. In a separate bowl, whisk the egg yolks and sugar together until light in color and creamy.
3. Add the cooled chocolate to the egg yolk mixture and stir until combined. Set aside.
4. In a mixing bowl, beat the egg whites until foamy. Add the cream of tartar and continue to beat until stiff peaks form.
5. Fold the egg whites into the chocolate mixture in 3 additions. Be gentle and thorough to maintain the airiness of the batter.
6. In a separate bowl, whip the heavy cream and vanilla together until stiff peaks form.
7. Fold the whipped cream into the chocolate mixture in 2 additions.
8. Pour the batter into a springform pan and chill in the fridge for at least 4 hours or overnight.
9. Serve chilled and enjoy!
