Is there something that can be used in place of cream cheese when making cookies with the press?

Cream fraiche

Consider ricotta, Devon cream, or even yogurt that has been drained overnight.

Butter, I should think. There are a lot of recipes for "spritz" cookies that use a cookie press, but don't require cream cheese. Here are a few: http://www.foodily.com/s/press-cookies-no-(cream-cheese) . Have fun!! ;o)
