I needed some chocolate whipped frosting, and all I had was rich's vanilla bettercream.  I added hersheys chocolate syrup, a couple tbs of hersheys cocoa powder, and a little salt.  It was the best chocolate frosting ever!!  It still had the light fluffy taste and texture!!  The chocolate wasnt a deep dark chocolate taste, but just right!  I also added some brown wilton food coloring, to give  it a darker chocolate color.  I hope this will help someone else who has the same dilemma

I have always used Frostin’ Pride which is almost the same & it comes in chocolate flavor so have never had to add more   Yes it soooo very good!:)
