Dunkin’ Donuts Butter Pecan Iced Coffee Copycat Recipe
This Dunkin’ Donuts butter pecan iced coffee copycat gives you that sweet, nutty, caramel-edged drink without a drive-through trip or a line at the window.
It comes together in about 10 minutes, and once you have the butter pecan syrup made, you can keep it in the fridge all week.
Why I Love This Recipe
The syrup is what makes this work. It’s got a real toasted, slightly salty quality that plain pecan or vanilla syrups don’t have, because you actually brown the butter before you add anything else.
The drink itself is cold, sweet, and just strong enough that the coffee flavor holds its own against the dairy. It’s the version I keep coming back to on slow mornings when I want something that feels a little more than just iced coffee.
Recipe Ingredients
- 2 tbsp unsalted butter – Browned first for that nutty, toasted base note; unsalted gives you control over the final sweetness
- 1/2 cup granulated sugar – White sugar keeps the syrup clear and light in color
- 1/2 cup water – Combines with sugar to make the simple syrup base
- 1/2 tsp pecan extract – The primary source of butter pecan flavor; find it near the vanilla in most grocery stores
- 1/4 tsp vanilla extract – Rounds out the pecan extract and adds depth
- 1/8 tsp fine salt – Balances the sweetness and sharpens the buttery flavor
- 2 cups strong brewed coffee, chilled – Brew it double strength or use cold brew concentrate cut 1:1 with water
- 1/2 cup whole milk – Adds creaminess without being too heavy; swap details in Variations
- 1 cup ice – Enough for 2 glasses; add more if you like a colder, more diluted drink
Variations / Substitutions
- Pecan extract swap – If you can’t find pecan extract, use 1/2 tsp butter extract plus an extra 1/4 tsp vanilla; the flavor will be slightly less nutty but still rich.
- Milk alternatives – Oat milk gives the closest creamy texture to whole milk; almond milk works but the drink will taste a bit thinner.
- Sweetener swap – Brown sugar instead of white makes the syrup slightly darker and adds a mild molasses note that works nicely here.
- Extra heat – A pinch of cinnamon stirred into the syrup while it simmers adds warmth without tipping into spiced coffee territory.
- Dairy-free – Use vegan butter in place of unsalted butter for browning; it won’t brown quite as deeply but still delivers a nutty flavor.
- Lighten the sweetness – Use 2 tbsp of syrup instead of 3 tbsp per serving if you prefer a less sweet drink; the coffee flavor comes forward more.
If you enjoy making flavored coffee syrups at home, the Dunkin’ Donuts Brown Sugar Oat Milk Iced Coffee Copycat Recipe uses a similar homemade syrup approach.
How To Make Butter Pecan Iced Coffee
Step 1: Brown the Butter and Build the Syrup
Set a small saucepan over medium heat and add the 2 tbsp unsalted butter. Let it melt and then keep cooking it, swirling the pan occasionally, for about 3 to 4 minutes. You’re waiting for the milk solids at the bottom to turn amber and smell nutty, not just toasted. Pull it off the heat the moment it smells like caramel.
Pour in the 1/2 cup water carefully since the butter will spatter a little, then add the 1/2 cup granulated sugar and the 1/8 tsp fine salt. Return the pan to medium heat and stir until the sugar fully dissolves, about 2 minutes. You should see no granules when you tilt the pan.
Step 2: Simmer and Flavor the Syrup
Once the sugar is dissolved, bring the syrup to a gentle simmer and let it cook for 3 minutes without stirring. It won’t thicken dramatically; you’re just driving off a bit of water so the syrup coats the back of a spoon lightly. Remove from heat.
Stir in the 1/2 tsp pecan extract and the 1/4 tsp vanilla extract. The syrup will smell intensely nutty right now, which is correct. Let it cool to room temperature, at least 15 minutes, before using it in your drink.
Step 3: Assemble the Iced Coffee
Fill 2 tall glasses each with 1/2 cup of ice. Pour 1 cup of the chilled strong brewed coffee into each glass. Add 3 tbsp of the butter pecan syrup to each glass and stir well for about 10 seconds so the syrup fully combines with the cold coffee rather than pooling at the bottom.
Step 4: Pour and Garnish
Pour 1/4 cup of whole milk into each glass over the back of a spoon if you want a layered look, or just add it and give the drink a quick stir. Serve immediately with a straw, and if you have any toasted chopped pecans on hand, scatter a small pinch on top for a nice finish.
Recipe Tips
- Make the syrup ahead. The butter pecan syrup keeps in a sealed jar in the fridge for up to 2 weeks. Give it a quick stir before using since the butter can separate slightly when cold.
- Coffee temperature matters. Use fully chilled coffee or cold brew. Hot or even room-temperature coffee will melt the ice fast and water down the drink before you finish it.
- Watch the browning closely. Browned butter goes from amber to burnt in about 30 seconds. Stay at the stove and use your nose as much as your eyes.
- Syrup yield. This recipe makes about 3/4 cup of syrup, enough for 4 drinks. Scale the coffee and milk portions as needed without remaking the syrup.
Bake times vary slightly depending on your stove burner, so adjust the browning step accordingly:
| Burner Size | Butter Browning Time | Syrup Simmer Time |
|---|---|---|
| Small | 4 to 5 mins | 3 to 4 mins |
| Medium | 3 to 4 mins | 3 mins |
| Large / high BTU | 2 to 3 mins | 2 to 3 mins |
How To Store
- Refrigerate – Store leftover butter pecan syrup in a sealed glass jar for up to 2 weeks. Keep pre-made iced coffee (without ice) in a covered container for up to 2 days.
- Serve Cold – The assembled drink is best made fresh. If you’ve stored coffee and syrup separately, just pour over ice when ready.
What To Serve With Butter Pecan Iced Coffee
A buttery, lightly sweet pastry is a natural match here because the richness mirrors the flavor in the drink without competing with it. A croissant or a glazed donut works well, and the flaky or fried texture gives you something to contrast with the cold, smooth coffee. If you want something more filling, a slice of banana bread alongside it is a solid pairing since the warm spice in the bread plays off the nutty syrup.
Frequently Asked Questions
Can I use instant coffee instead of brewed coffee?
Yes. Dissolve 2 tsp of instant coffee in 2 cups of hot water, then chill it completely before assembling the drink. The flavor will be slightly less complex than fresh-brewed but it works fine.
How sweet is this compared to the Dunkin’ original?
Using 3 tbsp of syrup per serving lands close to the Dunkin’ version. If you’ve had their butter pecan swirl and found it very sweet, start with 2 tbsp and taste from there.
Can I make a hot version of this?
Yes. Skip the ice, use hot freshly brewed coffee, and stir in 2 to 3 tbsp of warm syrup. Steam or froth the milk separately and pour it on top.
Will the butter solidify in the syrup once it’s refrigerated?
A small layer may form at the top when cold. Give the jar a good shake or stir before measuring out the syrup and it will incorporate back in easily.
