All of a sudden my buttercream is getting globs of white in it. It isn't from lack of mixing the color in it. It almost looks like they are clumps of shortening that aren't blending or creaming properly. I have tried creaming it longer but it still is happening. Does any one have any advice or tips? Has this happened to anyone else?

My buttercream did this too for the green army cake I just made. I put it in my mixer and beat the heck out of it, and it helped. But made the frosting too whipped and yucky to use. I have never colored buttercream before, I always use white, so I was left wondering how people color this stuff without screwing up the frosting. I always hear dont overwhip...but its hard not to when blending color.

I use YOUR recipe! lol. Now I know you said it doesn't matter how much you whip, but I found that it smooths better when its mixed just enough. It get very airy like whipped cream if I beat it too much. Not as thin of course, its still thick, but very airy and (to me) harder to work with sinc e I am sooo new to this all and dont have much experience with frosting cakes. I use americolor gels...and the color did not mix in well. Thre were small white spots that looked like crisco...but I will tell you this, when I make your frosting, I always beat the crisco vanilla, milk and a little bit of p. sugar VERY well to get it all creamy and mixed...then I add in the rest of the bag of thep. sugar...so I know its not chunkcs of crisco.
