IRVINE, CALIF. — Taco Bell Corp., a division of Louisville, Ky.-based Yum! Brands, is debuting a Cool Ranch flavor of Doritos Locos Tacos on March 7.

The introduction follows the success of the original nacho cheese Doritos Locos Tacos; more than 350 million were sold since last year’s launch.

“There has been enormous interest in the new Cool Ranch flavor of Doritos Locos Tacos and people are wondering why it took so long,” said Greg Creed, chief executive officer of Taco Bell. “Originally we had planned to launch the Cool Ranch flavor in the same year as the introduction of Doritos Locos Tacos. However, the demand for Nacho Cheese Doritos Locos Tacos was so strong that we worked closely with our partner Frito-Lay to increase our capacity and meet the needs of both Doritos Cool Ranch and Nacho Cheese fans.”

The new product features a taco shell made out of Cool Ranch Doritos chips, filled with ground beef, shredded lettuce and cheddar cheese.
