Everytime I make icing, I get LOTS of air bubbles. Even when I spread it on the cake and smooth it out, they seem to pop up from way down deep.
What could be causing this and is there a way to get rid of them once I have them?

Thank you

I discovered that when making icing, make enough that covers the beater. This prevents the air bubbles and makes it very smooth when applying to the cake. In my KA mixer 6qt i can do 3 batches.

Sharon Z (aka: SugarShack) has a YouTube video that you should watch. There is so much to making a good icing she tells all
Also Serious_Cakes has one I think.
