Some Gossip Girl fan communities on social media platforms like Tumblr also share links to great Chuck and Blair fanfics. You can follow relevant tags such as #ChuckandBlairFanfic or #GossipGirlFanfic and you might come across some hidden gems that are not as well - known on the bigger fanfic platforms.
Archive of Our Own (AO3) is another great place. It has a more organized tagging system.

The community on AO3 also provides useful reviews and comments to help you decide which ones to read.
You can start by looking on fanfiction.net. It has a large collection of Gossip Girl fanfics, and you can easily search for Chuck and Blair - centered ones. Just use the search bar and type in 'Chuck and Blair Gossip Girl' and you'll get a bunch of results.
There's also 'Chuck and Blair's New Beginning'. This fanfic takes a different approach. It starts with them in a new city, away from all the drama of the Upper East Side. They have to build their relationship from scratch without the influence of their families and the gossip mill. It's a refreshing take on their story.
Characterization is key. A good Blair and Chuck fanfic should have them act like they do in the show. Blair's strong - willed, sophisticated nature and Chuck's charming yet brooding persona need to be spot - on. For example, if a fanfic has Blair cowering at the slightest problem, it's not true to her character.

I'm not sure about the single 'best - known' author as there are many talented ones. But some of the more popular ones are those who have been writing for a long time and have a large following. You can often find them on fanfiction platforms where they get a lot of reviews and favorites.
