no, room temp. and it is added to the stiff peaked egg whites
Good Luck!!!
I've tried to make this 2 twice and followed the recipe to a T and it didn't work out either time. I have no idea where it went wrong. 
I don't think I'll ever try to make it again. I bet it taste really good too.
Well, I'll have a batch of my old stand by (shortening buttercream - yuk) waiting in the wing if it doesn't come out. Not a cake by request - just wanted to try and see if I can make it. I hate the sweetness of the Wilton recipe (shortening, conf. sugar, etc.). Funny, since that's the icing I get the most requests for - I personally like a nice light whipped icing but that's what makes the world go round.....differences. Wish me luck.
BJ - if you want to try another great recipe for BC (not SMBC) try SeriouCakes recipe:
The recipe:
22 tbs salted butter, softened (about 3 sticks)
2/3 c. Crisco shortening
5-7 tbs heavy cream
2 tsp clear vanilla
2 lbs powdered sugar (about 8 cups)
1-3 tbs corn syrup
Yum! Something I didn't put in the video-you may need more or less liquid depending on the weather. Very hot and humid out-add less cream, very dry-add more. And if you're wondering about the corn syrup, it doesn't add to the sweetness of the frosting but it does add elasticity to help keep the frosting from cracking and adds a nice 'gleam' to the cake.
here is a link for how she makes it:
it super good, not too sweet - def not a sweet as the wilton recipe.
Good luck with you SMBC, it is a wonderfully tasting frosting but it is tempermental.
