If you’re a coffee lover, there’s a good chance you’ve treated yourself to the refreshing and delicious Dunkin Donuts Iced Coffee at least once.

But what if you could make the same iconic drink right in your kitchen — fresh, cold, and customized just how you like it?
Good news: you can! This Dunkin Donuts Iced Coffee Recipe is not only simple but tastes just like the one you’d grab from your local Dunkin drive-thru — maybe even better. Let’s dive into how to make this chilled coffee masterpiece from scratch!
☕ What Makes Dunkin Donuts Iced Coffee So Good?
Dunkin Donuts has perfected the art of iced coffee. It’s not just coffee poured over ice — it’s a carefully brewed, double-strength coffee that stays bold and flavorful even after the ice melts. Unlike many iced coffees that become watery, Dunkin’s version remains rich and satisfying until the last sip.
Here’s why their iced coffee stands out:
- Freshly brewed every time – Dunkin brews its iced coffee hot and then rapidly cools it.
- Customizable flavors – From caramel to mocha to French vanilla, Dunkin offers endless flavor options.
- Perfect sweetness balance – Their liquid cane sugar mixes evenly, so there’s no gritty sugar at the bottom of the cup.
- Creamy consistency – Whether you add whole milk, oat milk, or cream, it always has that signature smooth texture.
Now that you know the secret behind the magic, let’s recreate it step-by-step!
🧊 Homemade Dunkin Donuts Iced Coffee Recipe
Ingredients
To make the perfect Dunkin-style iced coffee, you’ll need:
- 1 cup of Dunkin Donuts Original Blend Coffee grounds (or any medium roast coffee)
- 4 cups of water
- Ice cubes (enough to fill your glass)
- 2 tablespoons of liquid cane sugar (or simple syrup)
- 2 tablespoons of cream or milk (whole milk, half & half, or any alternative)
- Optional: flavor shot or swirl – such as vanilla, caramel, hazelnut, or mocha
Pro Tip: Dunkin’s “flavor shots” are unsweetened and sugar-free, while their “swirls” are sweet and creamy. You can replicate either at home depending on your taste!
Equipment Needed
- Coffee maker or French press
- Large heatproof container
- Measuring cups and spoons
- Stirring spoon
- Glass for serving
🧾 Step-by-Step Instructions
Step 1: Brew Double-Strength Coffee
Dunkin’s iced coffee is brewed double-strength to maintain its bold flavor when poured over ice.
To make it:
- Use 2 tablespoons of coffee grounds per 6 ounces of water instead of the usual 1 tablespoon.
- Brew using your coffee maker, French press, or pour-over setup.
- Once brewed, let the coffee cool slightly — about 15–20 minutes.
Step 2: Sweeten the Coffee
While the coffee is still warm, stir in liquid cane sugar or simple syrup. This ensures the sugar dissolves completely and gives your iced coffee that smooth, consistent sweetness.
Simple syrup recipe:
- Combine 1 cup water and 1 cup sugar in a saucepan.
- Heat until sugar dissolves, then let it cool.
- Store in a jar in your fridge for up to 2 weeks.
Step 3: Chill the Coffee
Once sweetened, place the coffee in the refrigerator to cool for at least 30 minutes. You can even make it ahead and keep it chilled overnight for a stronger flavor.
Step 4: Add Ice and Milk
Fill a tall glass with ice cubes. Pour your chilled coffee over the ice, leaving space for milk or cream. Add 2 tablespoons (or more) of milk or cream, and stir well.
Step 5: Customize Your Flavor
Now it’s time to make your iced coffee taste just like your favorite Dunkin flavor!
Here are some popular options:
- French Vanilla Iced Coffee: Add 1 teaspoon of vanilla extract or a splash of vanilla syrup.
- Caramel Swirl Iced Coffee: Mix in 1 tablespoon of caramel syrup and top with whipped cream.
- Mocha Iced Coffee: Add 1 tablespoon of chocolate syrup for a rich, cocoa twist.
- Hazelnut Iced Coffee: Stir in a splash of hazelnut syrup and a drizzle of cream.
Step 6: Serve and Enjoy!
Give your iced coffee a final stir, pop in a straw, and enjoy that authentic Dunkin Donuts Iced Coffee flavor — homemade and perfectly refreshing!
Pro Tips for Perfect Dunkin Donuts Iced Coffee at Home
- Always use fresh coffee beans. Dunkin’s smooth taste comes from its medium roast beans — avoid dark roast for this recipe.
- Chill before icing. Pouring hot coffee directly over ice can make it watery. Always cool it first.
- Use filtered water. The cleaner the water, the purer your coffee flavor.
- Customize the sweetness. Adjust the amount of syrup based on your preference — Dunkin drinks tend to be medium-sweet.
- Use coffee ice cubes! Freeze leftover coffee into ice cubes to prevent your drink from getting diluted.
