Hi all...Does anyone know by experience if they have added another flavored extract to an existing batch of vanilla buttercream...and how it tasted?

I have bought a huge tub of vanilla buttercream at my local cake store (which if fabulous...better than my own bc..IMO). I have a cake to do this weekend and they wanted rum buttercream. I have the rum extract but wanted to know if it would be okay to add to the vanilla buttercream? The cake itself will be a rum cake with cream cheese filling w/ strawberries and pineapple. Customers choices not mine.

Thanks for your help!!

sounds good.

I add Almond extract to mine all the time..

I also change-up my regular buttercream by adding flavors. I think you should be just fine.

I am sure it would work fine but you may want to do a cup's worth to try, just in case you don't like it. Better than ruining a whole batch worth of buttercream. Believe me, I speak from experience!!

I would start with just a tiny little drop, mix it well and taste. Keep adding until it is the right strength. Keep a count of the amount you used and then you can just multiply up by the number of cups of icing you are planning on using. Sorry not more specific but it just depends on how strong your flavouring is, and how strong you want the flavour will be in the end.

Vanilla goes with everything, so if you are worried about the conflicting flavors, don't be.

I added brandy extract to a standard buttercream and it actually was teh favorite filling of a big wedding cake I did
