It might help to post the recipe you use? Also what do you mean by split ??
It's separating in the bowl 
I've used sugarshacks recipe with the exception of the coffee creamer. I've tried adding more sugar and meringue powder but it isn't happening, I think the buttercream fairy is against me as I can never make buttercream no matter how hard I try!! Any suggestions?
Thanks
Well, if you didn't use the creamer than that is not Sugarshacks recipe. You need to follow her recipe and directions exactly. Do you mix in a KA mixer or hand mixer. She uses the KA on a low speed. If it's separating my guess is you used plain water and didn't mix it long enough. Try following her recipe exactly and see if you have better results.
The secret to success with any BC recipe in my opinion is the mixing method and than the ingredients.
