How Much Caffeine is in Dunkin’ Donuts Coffee?

If you’re a coffee enthusiast, you have likely stopped by a Dunkin’ Donuts coffee shop a time or two. As you order your hot drink or iced beverage, have you ever wondered how much caffeine is in a Dunkin’ coffee?

A few of our readers have asked us that very question, which prompted me to do the research and publish this caffeine report.

Read this guide for a complete overview of the amount of caffeine in hot coffees, iced coffees, and specialty frozen drinks on the Dunkin’ menu.

Caffeine Information Guide

Dunkin’ Coffee

Here is a quick reference guide to the amount of caffeine (based on standard brewing methods) in the various coffee beverages at Dunkin’ Donuts.

The top half of the table summarizes caffeine content in original brewed coffee and hot espresso-based drinks.

The bottom section of the table lists caffeine values for cold drinks. The coffee lover can check the amount of caffeine in Dunkin’s iced coffee and other cold espresso drinks (listed by available sizes) to make a more informed decision when ordering.

Amount of Caffeine Decreases When Milk is Added

Ordering milk with your coffee reduces the amount of caffeine per serving.

The main reason is because the milk takes up space in the cup. As a result, there is less coffee and less caffeine.

Here is a quick list of the amount of caffeine in a hot brewed coffee with whole milk, by size:

The amounts of caffeine are the same whether you select skim milk, whole milk, or a non-dairy option such as almond milk.

A small iced coffee has 196mg of caffeine, half the amount of caffeine in a large size. Adding a dairy option reduces the caffeine value by approximately 20 milligrams.

Flavored Iced Coffees Have Less Caffeine

If you’re a coffee drinker who enjoys a sweeter cup of coffee, stop by the popular fast food chain and choose from various flavors, including French vanilla, mocha swirl, butter pecan, or caramel swirl.

Adding a flavored syrup decreases the total amount of caffeine in a Dunkin’ iced coffee compared to a standard unflavored drink.

Here is a quick summary of the caffeine content, based on a size medium:

Hot & Iced Teas

Dunkin’s reports indicate that an iced chai latte has approximately the same amount of caffeine as the standard hot version of the chai latte.

Here are the caffeine levels in Dunkin’s hot teas and iced teas, including decaf and sweetened teas.

Dunkin’ has not yet provided a report of how much caffeine is in a matcha latte, but our beverage guide for the frozen matcha latte provides nutrition facts, calories, and ingredients.

Hot Chocolate

An Original hot chocolate drink from Dunkin’ contains a fairly nominal amount of caffeine. The small drink has nine milligrams of caffeine per serving.

Coffee lovers who enjoy the blended flavors of a mocha style hot chocolate can select the Espresso Hot Chocolate. It contains brewed espresso coffee and between 127mg and 136mg of caffeine, depending on size.

Review the following table for the amount of caffeine in hot chocolate drinks, by size.

Nutritional Notes

Hot chocolate is made with a significant amount of added sugars. Ingredients include sugar and corn syrup solids.

Here are select nutrition facts for a Dunkin’ Original Hot Chocolate beverage (based on a size medium).

Percentage daily value (% DV) illustrates how much a nutrient contributes to a daily diet of 2,000 calories, the standard amount used by the FDA for general nutrition advice (your value may be higher or lower).

As noted above, 45g of added sugars equate to a 90% daily value. That is significant.

Said differently, a medium hot chocolate contains 90% of the recommended limit of added sugars (50 grams) for an entire day.

Informational Allergen Notice: Dunkin’ drinks and food products are prepared in a common facility and/or using shared equipment. Accordingly, all food and beverage products may contain or come into contact with allergens, including nuts, fish, soy, sesame, milk, and wheat.

Refreshers & Frozen Drinks

Made with green tea and infused with B vitamins, flavored iced Refresher drinks are a popular choice in the summer.

Select Strawberry Dragonfruit or Mango Pineapple. The amount of caffeine is the same for either flavor option.

Availability of flavors may vary by location.

Customize a Dunkin drink for your individual preference by selecting from a wide array of flavors. Frozen coffee can be made with butter pecan swirl, caramel swirl, French vanilla swirl, or mocha swirl.

With the exception of mocha swirl, adding flavor shots do not change the amount of caffeine in a frozen coffee.

That said, adding flavor does change the ingredients.

Ingredients in Frozen Coffee

Here is the ingredient information for Dunkin’s frozen coffee and the flavored syrup options.
