Whipped Chocolate Caramel Ganache

Put the heavy cream in a glass measuring cup and microwave on high for 45 seconds, add chocolate and microwave another 30 seconds Stir until its smooth, add the vanilla extract and stir to combine, set aside so that it will cool before adding to the caramel.
In large saucepan add the sugar, turn heat to med/high and let sit until it starts to liquefy. Start stirring with a heat proof spatula. The sugar will crystalize but that's alright -- keep stirring until its all liquid. Stop stirring and let it cook until it turns amber in color, then add the butter and stir to combine.
Remove from heat and add the chocolate cream. Stir until its incorporated. Store in a container at room temperature until ready to use. Note: If you make this ahead of time, simply place the bottle or jar in hot water to warm the caramel so it's pourable.
Heat cream to scalding (not boiling). Pour over the pieces of chocolate that are in a mixing bowl. Let sit 5 minutes then stir until there are no pieces of chocolate and it's smooth and shiny, then add the chocolate caramel sauce and stir to combine.
Place bowl in an ice bath and stir or whisk until it's cool but not cold -- it will stiffen fairly quickly if it gets too cold. Remove from the ice bath and beat with a mixer or whisk until the ganache is fluffy and spreadable. Frost the cake immediately. Best served at room temperature.
