Article: An ATM that spits out cupcakes instead of cash is now filling a popular demand in the American market:late-night desire for freshly baked sweets. In six cities across the country, sugar addicts can now purchase a cupcake for $4.25 from an automatic machine 24 hours every day.The freshly baked goods are made by the California-based cupcake shop Sprinkles. The idea came to the company's co-founders Candace and Charles Nelson when Candace was pregnant with their first child. Candace thought it was ridiculous that she owned cupcake bakeries aad couldn't get a freshly baked treat at an unusual hour.That desire inspired the company's first cupcake ATM in Beverly Hills,Calif.in 2012.

In terms of the company, the-machine allows Sprinkles to do the impossible:increase hours of operation without raising costs.Now the company can sell cupcakes around the clock through the ATM without paying employees. Now the company is partnering with a Middle Eastern company to open 34 new locations abroad.
