They do sell it at the Brit shop called Stonemanor.
I fact they had quite a few different ready made flavors there when I was there the last time!
There are 2 Stonemanor shops so check which one is closets and/or give them a call first

I use Philadelphia cream cheese as base for frosting - can be found in nearly all supermarkets.
