Creamed butter, sugar, and eggs.

So when I posted about the chocolate chip cookie fail, one thing I didn't get a picture of was how strange the caramel + brown sugar + butter + eggs looked. The butter clarified and didn't fully incorporate into the caramel.

This is what creamed butter, sugar, and eggs is supposed to look like ...

I wish I better understood the chemistry of what is going on with this magical concoction when making cookies.

Update: I got a great comment from donaleen about a Baking 911 blog post that goes into great detail about creaming butter and sugar and the considerations of the temperatures involved. Well worth a read.
