These days, there's no easy birthday dessert for your child to share with friends at school. Many schools are no-nut zones, and many kids have dairy or egg allergies. But Cherrybrook Kitchen, a new local cake-mix company, has a solution. Its four cake and cookie mixes ($3.99 to $5.29) are kosher and vegan, and mixes such as the chocolate cake can be turned into cupcakes as well. Cherrybrook's Patsy Rosenberg, 35, of Weston, developed allergies four years ago and came up with the mixes, she says, ''to create a worry-free experience and capture that sense of pure abandonment that comes when you would sit down in front of a plate of cookies or a cake." Those without allergies will love them too.
Cherrybrook mixes are at many Whole Foods Markets and in Shaw's Wild Harvest sections, or go to www.cherrybrookkitchen.com.
