Just a few months after entering the U.S. market via Tucson, a Mexican bakery chain is quickly expanding after enthusiastic response from customers.

Suspiros Cakes, which specializes in gourmet cakes and pies, opened its first shop on 12th Avenue and Nebraska Street in February, followed by a second location on 12th and Ajo Way a few weeks later.

Now the company is preparing to open a store at 5606 E. Broadway, just east of Craycroft Road, next month and a fourth shop at 1686 W. Valencia Road, near Midvale Park, in August.

Suspiros, headquartered in Hermosillo, Son., has more than 260 bakeries throughout Mexico. Its local opening was greeted by long lines of people familiar with the brand, said Oscar Ponce, marketing director.

“The biggest supporters have been Hispanics,” he said. “But, other local residents are hearing about us and coming in.”

He said on Mother’s Day and Father’s Day, the bakeries sold out of products.

“Our products are original and not something the competition can duplicate,” Ponce said. “We use homemade cream and Suspiros recipes.”

The bakery has 12 employees in a production kitchen — adjacent to the 12th and Nebraska location — and five sales employees at the two shops.

Founded in 2004 by Ana Lucia Fonseca de Esparza, Suspiros uses her family recipes for its decadent cakes and pies. There are more than 40 varieties.

Juan Pablo Briseño Valenzuela, director of U.S. operations, said Tucson was the “test market” for the company to gauge customer reception.

Ponce expects to have six Tucson shops open by the end of the year before exploring other markets next year.

The company is looking at the Phoenix area, Sierra Vista and Bisbee then plans to explore Los Angeles, San Diego and cities in Texas and Nevada.

“We’ll go into markets where customers already know our brand,” Ponce said.

Suspiros has shops in 22 states throughout Mexico.
