Caridwen is so right! I tried to make a cinnamon cream combo (not DIY, it was on a site that creates flavors for you). I thought cinnamon would overpower the cream (I think it was Bavarian cream), so I had mostly cream in the mix. Oh Gosh It Was Nasty! I can't even tell you what it tasted like since I gagged so fast. And it wasn't because it was too sweet - I like sweet - it was...I dunno. I've looked at Whipped Cream flavors before, but honestly, I'm cream-shy.
That said, I ordered Cinna Cream from Rawr, but I haven't tried it yet; and if I get really brave, I thought this looked interesting:
