NEW YORK (AP) - Starbucks Corp. is testing a variety of toasty croissants and baked goods in nine San Francisco stores, with plans to eventually expand distribution nationally.

Among the items being tested: a whole wheat spinach croissant, a ham and cheese croissant, and a tomato, cheese and herb croissant. There's also a blueberry yogurt muffin, raspberry passion fruit loaf cake and lemon vanilla loaf cake, which replaces the current lemon loaf cake. Many of the items are served warmed, unlike its current lineup of baked goods.

Although there's no time frame for a national rollout, the Seattle-based company plans to start by expanding the offerings throughout the Bay Area.

A spokeswoman for Starbucks, Lisa Passe, noted that this was an operational test to see how stores would handle deliveries and heating the items.
