Copycat Dunkin’ Donuts Iced Coffee Recipe

Dunkin’ Donuts Iced Coffee Ingredients

These are the simple ingredients you need to make four servings of homemade Dunkin’-style iced coffee:

• 3/4 cup ground coffee: Dunkin’ Original Blend ground coffee will give you the closest familiar flavor, but another bold medium-roast coffee will also work.
• 3 cups cold water, divided: Use 1 1/2 cups to brew the strong coffee and stir in the remaining 1 1/2 cups after brewing.
• 1/3 cup granulated sugar: Add it while the coffee is hot so it dissolves completely.
• 1/2 cup half-and-half: This gives the coffee its smooth, creamy finish.
• Ice: Add ice only when you are ready to serve the coffee.
• Whipped cream, optional: Use it for a sweeter, dessert-style drink.

How to Make Dunkin’ Donuts Iced Coffee at Home

1. Brew Strong Coffee

Add 3/4 cup ground coffee and 1 1/2 cups cold water to your coffee maker. Brew according to the manufacturer’s directions.

This produces a stronger coffee than you might normally drink hot. That extra strength is intentional because the finished coffee will be diluted with additional water, cream, and melting ice.

2. Sweeten the Coffee While It Is Hot

Pour the freshly brewed hot coffee into a heat-safe pitcher. Add 1/3 cup granulated sugar and stir until the sugar has completely dissolved.

Do not wait until the coffee is cold to add the sugar. Granulated sugar dissolves much more easily in hot coffee and will not leave a gritty layer at the bottom of your glass.

3. Add the Half-and-Half

Stir 1/2 cup half-and-half into the sweetened coffee. The half-and-half softens the stronger brew and creates the creamy coffeehouse-style finish.

4. Add the Remaining Cold Water

Stir in the remaining 1 1/2 cups cold water. Mix until the coffee, sugar, water, and half-and-half are evenly combined.

5. Chill the Coffee

Cover the pitcher and refrigerate it for 1 to 2 hours, or until the coffee is completely cold.

Chilling the mixture before serving is an important part of the recipe. Pouring warm coffee directly over ice causes the ice to melt quickly and can make the drink taste watered down.

6. Pour Over Ice

Fill four tall glasses with ice. Stir the chilled coffee mixture, pour it over the ice, and add whipped cream or flavored syrup if desired. Serve immediately.

Tips for the Best Dunkin’-Style Iced Coffee

Use a Bold Medium-Roast Coffee

Dunkin’ Original Blend is a medium-roast coffee, making it a natural choice for this recipe. Another flavorful medium roast will work, but avoid using a very mild coffee because its flavor may disappear after the water, cream, and ice are added.

Measure the Ground Coffee

The 3/4 cup of ground coffee may look like a lot for 1 1/2 cups of brewing water, but this recipe begins with a concentrated brew. The additional cold water and half-and-half balance it after brewing.

Dissolve the Sugar Before Chilling

Stir the sugar into the coffee while it is piping hot. Continue stirring until you can no longer see sugar crystals in the pitcher.

Chill It Before Adding Ice

For iced coffee that tastes bold rather than watery, refrigerate the mixture before serving. Add the ice to individual glasses instead of storing it in the pitcher.

Freeze Coffee Ice Cubes

Pour leftover brewed coffee into an ice cube tray and freeze it. Coffee cubes keep your drink cold without diluting the coffee flavor as they melt.

Adjust the Sweetness Carefully

The recipe uses 1/3 cup sugar for four servings. For a less-sweet drink, begin with 3 tablespoons. For a sweeter coffee, add simple syrup to individual glasses after chilling.

Stir the Pitcher Before Pouring

The coffee and cream may separate slightly while refrigerated. Give the pitcher a good stir before pouring each serving.

Does This Taste Exactly Like Dunkin’ Iced Coffee?

This is a homemade copycat recipe rather than Dunkin’s proprietary commercial formula. The use of Dunkin’ ground coffee, a strong hot brew, sugar, cold water, and half-and-half creates a similar smooth, creamy coffeehouse experience using ingredients that are practical for a home kitchen.

Dunkin’ shops offer different dairy choices, sweeteners, flavor shots, and flavor swirls, so the exact taste of an order varies. This recipe gives you a reliable base that can be customized to resemble your usual order.

How to Make Dunkin’ Vanilla Iced Coffee

For a Dunkin’ vanilla iced coffee recipe, prepare the coffee as directed and add 1 to 2 tablespoons of vanilla syrup to each serving. Stir the syrup into the glass before adding the chilled coffee, then taste and adjust the sweetness.

To flavor the entire pitcher, stir approximately 1/4 cup vanilla syrup into the coffee after the granulated sugar has dissolved. Reduce the granulated sugar if your vanilla syrup is particularly sweet.

More Iced Coffee Flavor Variations

• French vanilla iced coffee: Add French vanilla syrup or French vanilla coffee creamer to each glass.
• Caramel iced coffee: Add caramel syrup and drizzle a little caramel around the inside of the glass.
• Mocha iced coffee: Stir chocolate syrup into the hot coffee before chilling or add it to individual servings.
• Mocha caramel iced coffee: Combine chocolate and caramel syrups for a richer drink.
• Extra-creamy iced coffee: Add another splash of half-and-half to each glass.
• Dairy-free iced coffee: Replace the half-and-half with oat milk, almond milk, coconut milk, or dairy-free creamer.
• Reduced-sugar iced coffee: Use less granulated sugar and sweeten each serving to taste.
• Frozen coffee: Blend the chilled coffee with ice until thick and frosty.

Troubleshooting Homemade Iced Coffee

Why Is My Iced Coffee Watery?

The coffee may not have been brewed strongly enough, or it may have been poured over ice before it was fully chilled. Use the full 3/4 cup ground coffee, refrigerate the mixture until cold, and add ice only when serving.

Why Does My Iced Coffee Taste Bitter?

Bitterness can come from over-extracted coffee, stale grounds, or coffee left sitting on a hot burner. Use fresh ground coffee and remove the brewed coffee from the heat promptly. A little additional half-and-half can mellow a bitter batch.

Why Is There Sugar at the Bottom?

The sugar was probably added after the coffee had cooled or was not stirred long enough. Add granulated sugar immediately after brewing and stir until it dissolves completely.

Why Did the Half-and-Half Separate?

Some separation during refrigeration is normal. Stir the pitcher before serving. If the half-and-half looks curdled rather than simply separated, it may have been old or added to unusually acidic coffee.

Why Doesn’t It Taste Like My Usual Dunkin’ Order?

Your usual order may contain a specific milk, liquid sugar, flavor shot, or sweetened flavor swirl. Begin with this coffee base, then add vanilla, caramel, mocha, or your preferred creamer until it tastes closer to the drink you order.

Iced Coffee vs. Cold Brew

Iced coffee and cold brew are both served cold, but their brewing methods and flavor profiles are different.

• Iced coffee is brewed with hot water, cooled, and served over ice. It usually has a brighter, more familiar brewed-coffee flavor.
• Cold brew is made by steeping coffee grounds in cold water for many hours. It is often smoother, more concentrated, and less acidic tasting.

This recipe is true iced coffee because it begins with hot-brewed coffee. It is a good choice when you want a cold coffee drink without waiting 12 to 24 hours for cold brew. You can learn more in Cold Brew Coffee vs. Iced Coffee.

How to Make Iced Coffee for a Crowd

Double the ingredients to make eight servings and prepare the coffee in a large heat-safe pitcher. Chill it without ice, then set up a coffee bar with glasses, ice, straws, half-and-half, dairy-free milk, whipped cream, and several flavored syrups.

This works especially well for brunch, baby showers, summer parties, holiday breakfasts, or mornings when several coffee drinkers are visiting.

How to Serve Copycat Dunkin’ Iced Coffee

Fill a tall clear glass with plenty of ice and pour in the chilled coffee. For an extra-creamy presentation, leave a little room at the top and slowly pour in another splash of half-and-half.

Add a straw and serve it with breakfast muffins, coffee cake, brownies, or another coffee-shop-style treat. For a sweeter drink, finish it with whipped cream and a drizzle of caramel or chocolate syrup.

More Treats to Serve with Iced Coffee

• Serve Moist Coffee Cake Muffins for an easy coffee-shop-style breakfast.
• Pair it with Super Easy Coffee Cake for brunch or a slow weekend morning.
• Try Irish Coffee Bars when you want a coffee-flavored dessert.
• Serve slices of Coffee Cheesecake Pie for an extra-rich coffee pairing.
• Add Fudge Espresso Ultimate Brownies for the chocolate-and-coffee crowd.

How to Store Homemade Iced Coffee

Transfer the prepared coffee mixture to a covered pitcher or airtight container and refrigerate it for up to 3 days. Do not store the coffee with ice because the melting ice will dilute it.

Stir the coffee before serving because the half-and-half may settle or separate slightly as it sits. Pour it over fresh ice and add toppings or flavored syrups just before drinking.

Can You Make This Iced Coffee Ahead of Time?

Yes. In fact, this recipe tastes best when it is made ahead because the coffee needs time to become completely cold.

Prepare the coffee mixture the night before, cover the pitcher, and refrigerate it overnight. In the morning, stir it well and pour it over fresh ice. This gives you a quick homemade iced coffee without brewing or waiting for hot coffee to cool during the morning rush.
