Warm the heavy cream in a saucepan over medium-low heat. Stir in the sugar and agave and simmer until the sugar is dissolved. Whisk in the cocoa powder, chocolate, and chili powder and stir until the chocolate is melted and the mixture is smooth. Remove the chocolate sauce from the heat and stir in the salt. Pour into a serving bowl or storage container. Serve warm drizzled over cake, ice cream or donuts.
