the last few cakes I have done in dark colors ( green and blue) look fine at first , but in the morning have little white spects in the buttercream . lucky for me it was cakes for family . has anyone had this happen before ? I have tried mixing the buttercream longer , that didnt work . anyone have any clue what im doing wrong ?

That happened to me one time. It almost looked like they were tiny lumps of powdered sugar that didn't get completely dissolved and didn't absorb the color. It looked like grey spots. Since then, I've always sifted and it hasn't happened again.

Don't know if that it, but maybe someone else knows. I'd love to hear if it might be something else.

This just happened to me yesterday. Now that the weather is cooler, the butter didn't fully "melt" as I was mixing my buttercream and there were little spots of butter in the frosting I dabbed at them with my finger after frosting the cake and I could mix them in, but next time I'll take more time to blend with the mixer to fully get them to "melt". The weather plays such a big part in baking!!

I would have this problem when I used to put a pinch of salt in my frosting without first dissolving it in the liquid.

thanks everyone for your help . i will try these things see if it makes a difference.

oh oh! maybe your paddle or whisk attachment is hitting the sides of your bowl and pulling the steel bits off the bowl. Make sure this is not the case it could be bad for you. I know this because it happened to us at school one time and our chef explained that this could happen and to throw out the buttercream or whatever it is you were mixing and get another bowl and make sure you adjust the tilt so it doesn't happen again. But that's your worst case scenario.

I had this happen to me twice, and both times I was in a rush and put the cakes in an airtight container directly after finishing it and didn't let the cake sit out and "breathe" a little before packaging it. Don't know for sure if that's what did it, but it's the only times I've had that happen.
