Your little diva has requested a birthday to remember. With chocolate. And unicorns.Thanks to Play with Your Food, she can have her cake and bake it, too.Started by two local ladies, the mobile party service brings the works for intimate baking celebrations for kids ages 4 and up. Honorees can choose from a range of options like decorate-your-own-cookie parties, marshmallow madness, or custom-themed shindigs.While dessert bakes, guests adorn their own aprons and go home with a goodie bag filled with homemade treats (to prevent on-site sugar overload). What’s more, the planners do the cleanup for you.And that’s the icing on the cake.For more information, go to playwithyourfoodparty.com.
