What are the best & yummiest flavorings to put in buttercream? I've fallen in love with swiss meringue buttercream when it is flavored well, like with chocolate. I'm not as crazy about it with just vanilla though. Any ideas?

I recently flavored my BC with caramel sauce...Yum! Here is a link. http://www.thatreallyfrostsme.com/2010/09/caramel-frosting.html

Not too long ago I got a request for Guinness Cupcakes with Baileys Buttercream. on first thought I was grossed out, but after making them, I liked them alot! The Baileys Buttercream is now one of my favorites!

Love love love orange....and coconut.

My all-time favorite is almond. But a close second is Lorann's champagne flavor. It doesn't really taste like champagne (at least not to me) but it's really yummy and people find it intriguing. It's impossible to identify.

I've done Mocha, i think the recipe i used was from the cake bible.
Also, pineapple and orange are great! Used lorann pineapple flavoring and for the orange, boyajian oil.
I made these flavors using neo-classic.

I love Nutella, white choc. raspberry, and peanut butter (using brown sugar instead of white when cooking). I hate raspberry BC but LOVE this so much I used it in my wedding cake.

Key lime. I made key lime cupcakes (just subbed KL juice for 1/2 the water in WASC and left out the almond) and then filled them with a mixture of softened cream cheese and strawberry ice cream topping. Then I added the rest of the block of cream cheese and about 2 tablespoons of KL juice to some buttercream I already had made, added a cup of powdered sugar, whipped it up and it was WONDERFUL!! Had a great tart/sweet taste.

I love Nutella, Peanut butter, almond, boysenberry, coconut, ummmm yeah I like buttercream.

I second the Baileys. I use a mixture of Baileys and heavy cream when I make that flavor. SO good on mocha or chocolate cake!

These sound delicious...I LOVE Guinness...so much.

I'm putting Nutella BC in my own cake this weekend. I swear I almost don't need a cake...just a bowl of that! I just also decided that I want to try "creme de menthe" in my BC and doing an Andes Mint type chocolate cake. Never tried it, but it sounds yummy

You can get boysenberry at liquor store that sells homebrew supplies, a friend made boysenberry wine. It comes in a can, I dont know if it is syrup or liquid. sorry.

I actually think I got my fruits mixed up and it was blackberry extract. Here is a link to all kinds of different extracts including blackberry. http://www.faeriesfinest.com/extracts.html Still haven't found an online source for boysenberry though. Im still searching.
