The famously limited menu at California’s iconic In-N-Out Burger has increased by one item — for the first time in 15 years.

Could it be onion rings, made fresh right before your eyes as you inch through the drive-thru lane?

Nope.

Could it be a classic hot dog? A meat-free patty?

Nope and nope.

It’s hot cocoa for customers in the warm-weather states of California, Utah, Arizona, Texas, Nevada and Oregon, where In-N-Out operates, according to our colleagues at the Orange County Register. (You residents of the “bomb cyclone” states will have to wait for your Double-Doubles AND your hot chocolate.)

An employee in the city of Orange told reporter Nancy Luna that the beverage is made with hot water, not milk, and is topped with mini-marshmallows. The 8-ounce drink is priced at $1.60. It’s available at select locations and has yet to be added to the company’s website.
