Copycat Dunkin’ Donuts Iced Coffee Recipe – Make It Yourself

There’s something about Dunkin’s iced coffee that just hits right—especially when you need a reliable caffeine fix on a hot morning. It’s smooth, not bitter, slightly sweet, and always refreshing.

Maybe you’ve tried recreating it at home with leftover coffee and ice cubes, but it never tastes quite the same. Too watery. Too bitter. Missing that signature Dunkin’ balance.

I was in that exact spot a few months ago. I had switched to working from home and realized I was dropping way too much money stopping by the drive-thru for a medium iced with cream and caramel swirl every morning. That $4 here and $5 there adds up—fast.

So I started digging. Reddit threads. Dunkin’ fan blogs. Barista TikToks. After a lot of trial and error, I finally landed on a homemade version that’s shockingly close to the real thing. And the best part? It’s simple, cheap, and you can batch it for the whole week.

Dunkin'-Style Iced Coffee (Copycat Recipe)

There’s just something irresistible about Dunkin’s iced coffee—it’s smooth, sweet, and never too bitter, making it the perfect pick-me-up on a hot morning.

If you’ve ever tried to replicate it at home with old coffee and a handful of ice cubes, you probably ended up with a watery, unsatisfying mess.

Equipment

• Coffee maker (drip machine or French press)
• Tall glass or reusable iced coffee tumbler
• Spoon or shaker bottle
• Measuring spoons and cups
• Ice
• Mason jar or pitcher for batch prep (optional)

Ingredients

  

• 3 tbsp ground coffee (medium roast; Dunkin’ Original Blend preferred)
• 6 oz hot water
• 1 cup ice
• 1/4 cup milk or cream (light cream, whole milk, half-and-half, or non-dairy alternatives like oat milk)
• 3 tbsp sweetened flavored syrup (e.g., caramel, mocha, French vanilla – Torani or Monin recommended)
• 1 tsp sugar (if not using syrup)

Instructions

 

• Brew Strong Coffee

  In a coffee maker or French press, brew 3 tablespoons of ground coffee using just 6 oz of hot water.

  This yields a double-strength brew ideal for iced coffee. If using a French press, steep for 4–5 minutes.
  
• Pour Over Ice and Add Sweetened Syrup

  Fill a tall glass or tumbler with 1 cup of ice. Pour the hot coffee directly over the ice.

  The melting ice will bring the strength to normal and cool it down. Stir gently to distribute the temperature.

  Mix in 2–3 tablespoons of your preferred flavored syrup (like caramel or vanilla).

  If you don’t have syrup, substitute with 1–2 teaspoons of sugar and a splash of extract (like vanilla or caramel flavoring).
  
• Add Milk or Cream

  Pour in 1/4 cup of your preferred milk or cream.

  Dunkin’ typically uses light cream or whole milk, but feel free to use your favorite dairy or non-dairy option.

  Stir until well blended and creamy.
  
• Taste and Adjust

  Sip and tweak to taste. If it’s too strong, add more ice or milk.

  Not sweet enough? Stir in a little more syrup or sugar.

Cooking Tips

• Use Dunkin’ Original Blend for an authentic flavor—available in most grocery stores.
• Brew in advance and refrigerate if you want zero dilution from ice.
• Make a batch: Multiply the recipe and store the strong coffee base in the fridge. Add syrup and cream right before serving for a fresher taste.
• Sweetness Control: Syrups already contain sugar, so adjust additional sugar accordingly to avoid over-sweetening.
