The Americans wrapped up victory in 73 minutes to win their 12th grand slam title together, adding the trophy to the ones they won at Wimbledon and the US Open last year and at the Australian Open in January.
"It feels good - we have a Williams Slam," Serena said. "We've four in a row now so we were really excited about that."
The top seeds are only the third doubles partnership in the history of the women's game to hold all four grand slam titles at the same time.
They will become the top-ranked doubles pairing on Monday, making Serena Williams only the sixth woman to hold top spot in the singles and doubles at the same time.
The sisters said they had no plans to play doubles more regularly on the women's tour, but will continue to play together at the grand slam events.
Next stop for both of them will be Wimbledon, where they have won the doubles four times, their last victory coming in 2009.
Serena, the defending champion in the singles, said they would stick to their usual routine as they head to London.
"We have the same prep every year," she said. "Just hit on the hard courts and play Wimbledon. That's our grasscourt season. One grasscourt tournament and we try to play very well. Nothing special."
