UCI junior Kelsey Lien has won a national Baskin-Robbins contest to create a new ice cream flavor, beating out a reported 40,000 fellow applicants with her “Nutty Cream Cheese Brownie” concoction, which will be next November’s “Flavor of the Month.” The economics major won a year’s supply of free ice cream and a trip to Boston, where she helped chefs mix up the first batch of her winning flavor at Baskin-Robbins headquarters. The annual online contest invites consumers to pick a base flavor, then add ribbons of ingredients like fudge or peanut butter and mix-ins like candy or cookie pieces.
