The chocolate brand known for "melting in your mouth" is M&M's. These colorful candy-coated chocolates, produced by Mars, Incorporated, feature a milk chocolate center that is designed to melt smoothly and effortlessly on the palate. The tagline "melts in your mouth, not in your hands" highlights the outer candy shell that helps to keep the chocolate from melting too quickly, allowing for easier enjoyment without mess. Since their introduction in the 1940s, M&M's have become a beloved snack worldwide, available in various flavors and limited editions, appealing to diverse tastes and preferences.
