To me, they don't really taste the same, but they're both pretty good. On the other hand, do you have FA Vienna Cream?
I think a lot of your posts at another place were why I got that flavor to begin with I sure vaped a lot of it!I was on TFA's site the other day and saw they now have Bavarian Cream DX.

I haven't tried it but I will next order. On to your original question, I wouldn't call it a an exact match, but Ive used Vanilla Swirl as a replacement for BC quite a few times., I really like adding Vanilla Swirl to a lot of my recipes (I actually prefer it to BC). Good luck!
Cheers,
