Hi, first time posting! I'm new to cake decorating and baking and have been wanting to try different recipes. I was watching amazing wedding cakes earlier and a beer buttercream was mentioned. I was just wondering if anyone had any recipes, I couldn't find any in the recipes section otherwise I wouldn't be asking 
Also couldn't find many by googling!
Suggestions anyone?
thanks!
welcome to cc. im sure they use a meringue based buttercream. guiness is a beer used quite a bit for baking..
They give the recipe on the website for the show. I'm going to be trying it for my dad's cake next month since he loves Guinness. Don't forget to boil it down to reduce it - it will make all the difference in the flavor!
I have watched that show last year too! I am kind of a WE and Food Network
junkie, but I don't watch Bridezillas much. That show spoils the beauty that make up weddings.
I don't know why I didn't remember to go to the website. Anyway, thanks! And watch how much of that frosting you drink! 
I just went on there too and didn't see it either 
Does anyone have the recipe?
I just located this..Maybe it will help?
1/4 cups stout beer, at room temperature, divided
1/2 cup butter, softened
1 (16-oz.) package powdered sugar
Beat softened butter at medium speed with an electric mixer until creamy. Gradually add powdered sugar and 1/4 cup stout beer, beating until blended after each addition. Beat 1 minute or until light and fluffy
There are a bunch of recipes if you search for guinness buttercream, here is one that i found.
Guinness Buttercream Frosting
Ingredients
2 Cup(s) Unsalted Butter (room temperature)
5 Cup(s) Sifted Powder Sugar
1/2 Cup Milk
1 Whole Scraped Vanilla Bean
1 Tablespoon Vanilla Extract
2 Cup(s) Guinness Extra Stout
Steps
In a sauce pan, simmer Guinness on low heat for 10-15 min, until it stout becomes reduced and thicker in consistency. Similar to a syrup. *Tip: keep your eye on the store, so stout does not over cook. Let cool.
In a stand alone mixer, cream your butter for 1 minute
Slowly add the powder sugar in thirds, alternating with a little milk each time till mixture is creamy.
Add scraped vanilla bean and vanilla extract.
Slowly add reduced Guinness a little at a time. Taste test to desired flavor. You may not use all the Guinness reduction.
What flavor cake would you use this with? My friend is having a BBQ and I think her crowd would be best to try this out on 
Thanks!

It is just me or the amount of liquid sees like a LOT!?! Adding 2 1/2 plus 1 Tbsp of liquid to 1 batch of BC is too much!
What I do to my Beer BC is just replace the liquid the recipe calls for with reduced stout. Same amounts. I've also used Sam Adams, it is not as dark but just as good, little lighter in beer flavor.
I also use it with chocolate cake and brush my cake with some more reduced beer.
I wish I had seen this post earlier, but when it says stout beer, in one of the replies, what are some types of stout beer besides the guin kind? Would budweiser or any kind of Budweiser product be considered stout? I want to make this cake tomorrow and I just want the best outcome or product.
The stouts from my understanding are the real deep dark brown types of beer. My guess would be if Bud makes a dark beer (and I have NO IDEA if they do or don't), it should work.
So, I we bought some stout beer the other day and I started to "simmer" it on the stove top. I got busy with one of my kids and my husband had to turn off the stove because the beer was boiling over everywhere! OOops! So, I'll have to experiment again tomorrow...this time I'll stay at the stove!

Yes, it does call for 2-1/2 cups of liquid, but the 2 cups of stout get reduced to a syrup, so I'm guessing that's down to about 1/4 cup or so, depending on if you're going for a maple syrup, a honey, or a molasses thickness.
Has anyone tried this frosting? I'm thinking of giving it a try this weekend for a friend's cake, but I don't know how to tell if it's any good...I like my buttercream sweet, and don't really care much for beer, so I'm pretty sure I won't like it, even if it's a fabulous recipe!!
My guess is no, no one else has made this. Or if they have they are no longer here seeing how the topic is two years old.
thanks so much for all of the great info! this is exactly what I've been searching for can't wait to try it!
Never thought of this one, but I will give it a try on one of my practice cakes.

Awesome I so want to try this recipe now. but my next cake is a Baby Welcoming so I really dont think they would care much for the flavor lol !!!!
(Its for my SIL )
Ok, I tried making the beer buttercream with a chocolate stout cake.
It was a hit (groom's cake), but I couldn't bring myself to try the buttercream...the smell of the reducing stout on the stove made me nauseous. My husband tried it and said it was ok (not a beer drinker), but the wedding party loved it.
I just made my regular vanilla buttercream and replaced the liquid with the reduced Guinness. And also brushed that on the cake like a simple syrup. The flavor isn't super strong, but people could tell!
