Hi,
There is a fabulous peanut-free and tree nut-free bakery in Northvale called Grandma's Kitchen (http://grandmaskitchennj.com/). The owner has a life threatening allergy to peanuts and tree nuts, so she understands and takes it seriously. I use this bakery for all family birthdays, parties, etc... It is such a find... thought I'd share. They can also do gluten-free, egg-free, and milk-free.
Hope this helps!
