LOS ANGELES — Nothing Bundt Cakes (N.B.C.) has expanded its corporate bakery footprint with the acquisition of six N.B.C. franchisee bakeries in the San Diego market. Financial terms of the transaction were not disclosed.

A portfolio company of Los Angeles-based private equity firm Levine Leichtman Capital Partners (L.L.C.P.), N.B.C. is a franchisor and operator of gourmet bakeries offering specialty Bundt cakes and related merchandise. N.B.C. has more than 320 locations in the United States and Canada.

“We are thrilled to add these San Diego bakeries to our company-owned portfolio that includes locations in Dallas, Texas, and Baton Rouge, La.,” said Kyle Smith, chief executive officer of N.B.C. “We believe that this acquisition provides us a great opportunity to improve our overall support to our bakery owners, while providing an extraordinary experience to our guests.”

L.L.C.P. said the San Diego bakeries are expected to eventually become N.B.C. training base on the West coast. They also will serve as additional outlets for research and development and product innovation, the private equity firm noted.

“This acquisition demonstrates our continued support of the N.B.C. investment,” said Matthew Frankel, a partner at L.L.C.P. “We remain focused on building value for the benefit of N.B.C.’s bakery owners, guests, employees and investors. We are excited to take part in the next chapter of growth for the San Diego bakeries.”

Nothing Bundt Cakes was founded in Las Vegas in 1997 by Debbie Schwetz and Dena Tripp. The company offers Bundt cakes in a variety of sizes and flavors.
