She is of Russian-Jewish descent.

Dennings made her professional debut with an appearance on HBO's Sex and the City in 2000, in the episode "Hot Child in the City". She then starred on the short-lived WB sitcom Raising Dad from 2001 to 2002 as Sarah, a 15-year-old raised by her widowed father. In 2002, Dennings appeared in the Disney Channel film The Scream Team as a teenager who stumbles into a group of ghosts.

From 2001 to 2010, Dennings maintained a blog, and also dabbled in video blogging on YouTube.

Dennings made her feature film debut in Hilary Duff's Raise Your Voice in 2004 as Sloane, a somber piano student. In 2005, she landed supporting roles as the daughter of Catherine Keener's character in The 40-Year-Old Virgin and as April in Down in the Valley. In 2006, Dennings played a rebellious teenager in the crime comedy film Big Momma's House 2.

In February 2011, Dennings was cast in 2 Broke Girls, a CBS sitcom written and produced by Michael Patrick King and comedian Whitney Cummings. The series debuted on September 19, 2011, and follows the lives of two underemployed girls. Beth Behrs co-stars as a Manhattan heiress who lost her inheritance, while Dennings plays a tough outspoken girl from Brooklyn. Dennings liked the idea of reaching a wider audience with her work, so she accepted the role on the network sitcom. On May 12, 2017, CBS canceled the series after six seasons.

Dennings is of Ashkenazi Jewish descent. In 2008, Dennings stated that Judaism "is an important part of my history, but, as a whole, religion is not a part of my life." She considers herself more ethnically and culturally affiliated than religiously so.
