The comedy, which stars Russell Tovey and Sarah Solemani as couple Steve and Becky, will return for six more episodes.
BBC Three also announced that it has ordered a second series of Pramface before the first run has even been broadcast.
The show features Scarlett Alice Johnson and Sean Verey as a couple coming to terms with becoming parents after a drunken night together.
Him & Her and Pramface were joined by Russell Howard's Good News, which has been handed a new multi-series deal by BBC Three.
BBC Three's controller Zai Bennett claimed that he runs "the channel that breaks new comedy in the UK", adding that the broadcaster will invest in comedy pilots to air online in a project called The Comedy Kitchen.
Among the six pilots that have been commissioned for the web are a project from The Boy With Tape On His Face - who previously won the 'Best Newcomer' award at Edinburgh - and a spoof news show from lookalike expert Alison Jackson.
Bennett said: "[Our] investment in The Comedy Kitchen and further online investment not only gives new talent and writers the time to grow and develop, but also ensures there is a clear nursery slope for them on to the channel, where we back series like Pramface with two series orders up front."
Johnny Vegas recently criticised Bennett for axing his comedy Ideal.
