KANSAS CITY, Mo.--Mars Inc. announced plans Wednesday for a $100 million expansion of its candy-making plant in Kansas, a facility that was the company's first new plant in 35 years.

The deal, which the company disclosed in advance of a Topeka economic development meeting, comes a little more than a year after the New Jersey-based company opened its $270 million plant south of the city.

Mars Incorporated is throwing a grand opening on Thursday for its new $270 million dollar plant near Topeka that will produce millions of chocolate bars and other sweets every day.

Company officials say the plant exists mostly to meet U.S. demand for itsĀ  M&M's- and Snickers-brand candy. It's the first new Mars plant in North America in 35 years.

The plant will have the capacity to produce 14 million bite-sized Snickers bars and 39 million M&M's each day.

The plant is bringing about 200 jobs to the Topeka area.
