The Seattle-based company, which has more than 18,000 locations around the world, raised its outlook for the year.
Global sales at cafes open at least 13 months rose 6 percent during the three months ended March 31. That included a 6 percent increase in the Americas, its biggest region, where the number of average transactions and spending per visit increased. In China and the Asia Pacific, where it's looking to grow, the figure rose 8 percent.
But it fell 2 percent in Europe, where Starbucks has struggled and has been working to turn around results.
For the quarter, Starbucks earned $390.4 million, or 51 cents per share. That's up from $309.9 million, or 40 cents per share, a year ago. Not including one-time items, it earned 48 cents per share, in line with analyst estimates.
Revenue rose 11 percent to $3.56 billion. But that was shy of the $3.58 billion Wall Street expected, according to FactSet.
Shares of Starbucks were down 3 percent in aftermarket trading.
The company says it now expect full-year earnings of $2.12 to $2.18, up from the previous forecast of $2.06 to $2.15 per share.
