In an interview with Complex, Grande reveals that "Baby I" was originally written by Kenneth "Babyface" Edmonds for Beyoncé. Grande also stated that it was actually Mac Miller who picked "Baby I" to be the second single for her album.

Grande opined that "Baby I" was more "sophisticated" and "mature" and showed off her musicality and vocals more than her previous hit single "The Way", which was part of what made her excited to release the song. She was revealing snippets of the song days before its release. The single was released to the digital retailer iTunes on July 22, 2013.

It was written and produced by Babyface, Tony Dixon and j.Que. A writer from Rap-Up describes the track as a "summertime record" which features Grande's "big vocals" over a "breezy beat". Several critics noted the '90s R&B music influence demonstrated in "Baby I", which will also be musically present on the rest of her album, Yours Truly. Additionally, '70s disco energy is also present in the song, with PopCrush describing it as "Mariah Carey gone retro".
