You crunch them, you love them, but do you really know the secrets of M&M’s? For over 80 years, these little colored candies have conquered the world with their irresistible taste and crunchy shell. But behind their success lies a surprising military story, bold innovations, and manufacturing secrets fiercely guarded.
What if I told you that M&M’s have even traveled to space? That their blue color was chosen by a global vote? Or that the recipe almost disappeared due to a cocoa shortage? Fasten your seatbelt; we’re diving into the fascinating universe of M&M’s!
I. A story that begins on a battlefield
From soldiers to candies: the unexpected origin of M&M’s
The story of M&M’s begins during the Spanish Civil War (1936-1939). Spanish soldiers had a brilliant trick to keep their chocolate from melting in the heat: covering it with a layer of hardened sugar. Inspired by this idea, Forrest Mars Sr., son of the founder of the famous Mars bar, decided to create a similar candy.
In 1941, M&M’s came to life and quickly became a staple for American soldiers during World War II. Why? Because they don’t melt in your hand, only in your mouth. A slogan that would become legendary!
The evolution of colors and iconic characters
The first M&M’s were only brown. It wasn’t until 1960 that red, yellow, and green colors made their debut, followed by blue in 1995 after a consumer vote.
And those little colorful characters we see in commercials? They appeared in 1954 with the introduction of peanut M&M’s. Today, each color has a well-defined personality: Red the arrogant, Yellow the naïve, Blue the cool… and Miss Green, who has become a feminine marketing icon!
II. The different varieties of M&M’s: much more than chocolate
The classic must-haves

Why are M&M’s so successful?
The secret lies in their unique texture: a perfect balance between the crunch of the coating and the melt of the chocolate. Add brilliant marketing and a global presence, and you get one of the best-selling candies in the world!
III. The behind-the-scenes of production: how are M&M’s made?
Have you ever wondered how these perfect little candies are made?
1. Chocolate, the king ingredient
Every M&M’s starts with a core of pure chocolate, melted and shaped into a small sphere. For the peanut versions, only the best peanuts are selected.
2. The colored coating: a highly precise process
- A sugar syrup is sprayed onto each candy, creating the crunchy shell.
- The candies are then dipped in natural food colorings.
- A laser marking applies the famous white “M” on each M&M’s.
3. A very strict quality control
Before reaching your bag, each M&M’s goes through rigorous testing:
✔️ Size and shape verification
✔️ Taste and texture testing
✔️ Guarantee of uniform colors
IV. Nutrition, allergens, and tips for enjoying M&M’s
