Caramel-Filled M&M's Are Coming Soon To A Candy Aisle Near You

We've had butterbeer M&M's, pecan pie M&M's, and earlier this year, fans voted coffee nut M&M's into existence. The latest (and possibly the greatest) coming flavor from the Mars Inc. company is caramel-filled M&M's, which will be released in May 2017 for the brand's 75th anniversary.

The caramel M&M actually took years to develop because it was a texture that the company had never experimented with before: soft and chewy. M&M's already come in smooth (regular and dark chocolate), crispy (pretzel), and crunchy (peanut) textures.

The caramel M&M launch will be one of the largest in the brand's history, which spent $100 million to develop the product.

"It was a big technological challenge for us," Hank Izzo, vice president of research and development for parent company Mars Chocolate North America, told CNN Money. "We never before had a M&M lentil with a true soft center, so we had to figure out how to not make the chocolate too sticky or too soft that it could collapse."
