I have been making buttercream icing for about a year now using a hand mixer. For my birthday/graduation my parents bought me a kitchenaid stand mixer (love it!
I decided to go to Suger Ed productions and purchase Sharon Zambito's Perfecting the Fine Art of Buttercream. I wish I would have known about it long ago. It was worth the purchase.
I think it depends on what method you are using as to what speed you use.
Cream the fat,
add the sugar on first speed so it doesn't look like it snowed in your kitchen. Once you get the sugar and liquid incorporated, you can start bumping up the speed to a 3 or 4. Using my old method, I used to let it run 10- 15 minutes.
After watching the DVD I mentioned above, I have it done in 5-6 minutes, but I adjust the speed and the amount of buttercream I am making.
I usually use level 3 on my Kitchenaid mixer.
So my question is, what speed is best to mix buttercream icing on it? I know if you over mix buttercream it gets air bubbles so I just wanted to know whats best using the stand mixer.
It's not so much the speed or overmixing that causes air bubbles, it's not having the bowl full enough to completely cover the beater... that incorporates air.
Thank you all for the advice! I tried it out making buttercream this weekend and it came out perfect! I have to say I love having a stand mixer, so much quicker then a hand one!
