can  any one give me an idea which is the best buttercream flavour with vanilla cake and chocolate cake? Because soon i'm going to give some samples for my freinds.

Thank you

no replys? please help me 

AMy favorite is chocolate. Caramel or vanilla would be good, too.

For years I used this mix of extracts in my buttercream icing & everyone loved it:

1 part vanilla  (whatever measure you want to use be it teaspoon, Tablespoon, cup or quart etc)

1/2 part butter

1/4 part almond

I always use 2 Tablespoon of this mixture in each batch of icing using 2# of powdered sugar.   I know that sounds like a lot but try it and see if you don't agree.  If you don't like that much cut down to 1 1/2 or even just 1 Tablespoon.

Some people don't like the almond so if you'd rather sub some lemon or orange extract.

You need at least 3 flavors to make a wonderful complex flavor that people will love.

Nothing beats vanilla (made with GOOD vanilla extract) to me!  I also really like a few drops of Lorann cheesecake flavouring.  I wouldn't say it tastes like cheesecake, but it does add some tastiness that my friends seem to love.

thank you everyone i'll try all suggestions and thank you onceagain
