Preheat oven to 350.

In large mixing bowl, cream butter and cream cheese. Add sugar and beat until smooth. Mix xanthan gum in with flour and add to cream cheese, mixing well. Add vanilla. Stir in cranberries and pecans. Form into 1″ balls. Place on ungreased baking sheet so they aren’t touching. They will not spread, so many will fit.
Bake for 10-12 minutes. Cool to touch and roll in powdered sugar.
