Smarties Vs. M&M’s (What’s the Difference?)

Smarties and the chocolate version of M&M’s look pretty similar, and you can be forgiven for thinking they’re almost the same with their colorful crispy sugar shells and chocolate centers. Still, there are some subtle differences that separate one from the other.

In this article, I’ll be comparing Smarties head-to-head against Chocolate M&M’s to show the actual difference between the two. Including brand, chocolate, ingredient, and nutritional comparisons.

Also, we’re taking a poll to find out which is the public favorite between the two products when it comes to flavor.

Which Came First Smarties or M&M’s?

Plain chocolate M&M’s were first introduced in the USA in 1941, which means they’ve been around for over 80 years; however, Smarties are even older and were first introduced in the UK by Rowntrees in 1882, making them over 140 years old.

When they were first released, Smarties were known as Chocolate Beans until 1938, when they were rebranded as Smarties. Nestlé now produces smarties since they took over Rowntrees in 1988.

M&M’s have remained a Mars product since they were originally introduced in 1941.

Ingredients Comparision

As you can see from the ingredients comparison table below, Smarties and M&M’s main ingredients are pretty similar, including sugar, skimmed milk powder, cocoa mass, and cocoa butter, all of which are ingredients you’d expect to find in chocolate.

The main difference between the two is that Smarties use natural flavors and colors which come from plant food and plant extracts, whereas M&M’s are produced contain artificial colors which can be identified by E numbers.

Smarties also contain orange oil to give the orange-colored sweets their unique flavor.

Manufacturer information confirms that Smarties contain 65% chocolate compared to M&Ms contain 70% and have a slightly thinner outer shell.

Please note that ingredients and chocolate percentages may vary depending on the country of manufacture.

Smarties Vs. M&M’s Nutritional Comparison

Moving on to the nutritional comparison between Smarties and M&Ms and to ensure the comparison is fair and accurate, this will be made weight-for-weight (per 100g).

A recommended serving of Smarties is half a 38g tube (around 16 smarties or 19g), whereas a serving of M&Ms weighs more depending on the pack size.

To ensure the comparison is consistent, I’ll be comparing Smarties against Milk Chocolate M&Ms (although other kinds are available).

Calorie Comparison

Weight-for-weight, Smarties, and M&M’s are similar in calories, and the reason M&M’s look like they contain a lot more calories per serving is because a serving of Smarties weighs less.

Per 100g, Chocolate M&M’s contain ten more calories than Smarties, although both kinds of chocolate would be considered high-calorie snacks.
