Microwave chocolate morsels and whipping cream in a glass bowl at MEDIUM (50% power) 2 to 3 minutes or until morsels are melted. Whisk until smooth. Gradually add butter, whisking until smooth. Cool, whisking often, 15 minutes or until spreading consistency.
This is very simple to make and is really great between the layers of the chocolate praline cake -- also works well with any chocolate cake
