Timing
Prep Time: 5 minutes
Cook Time (for syrup): 10 minutes
Cooling Time (for syrup): 30 minutes
Assembly Time: 2 minutes
Total Time: 47 minutes (but only 17 minutes of active time)
The homemade syrup can be made in advance and stored for up to 2 weeks, which means your subsequent coffee preparations will take just 2-3 minutes – that’s even faster than waiting in the Dunkin’ drive-through!
Step-by-Step Instructions

Step 1: Toast the Pecans
Preheat a small skillet over medium heat. Add the chopped pecans and toast for 3-5 minutes, stirring frequently to prevent burning. You’ll know they’re ready when they become fragrant and slightly darker. Remove from heat immediately and set aside.
Pro tip: Watch the pecans like a hawk – they can go from perfectly toasted to burnt in seconds!
Step 2: Prepare the Butter Pecan Syrup
In a small saucepan, combine sugar and water. Heat over medium heat, stirring until the sugar dissolves completely. Once dissolved, let it come to a gentle boil for about 3 minutes without stirring.
Reduce heat to low, then add butter and stir until melted. Remove from heat and stir in vanilla extract, butter extract, toasted pecans, and salt. The mixture will bubble up slightly – this is normal.
Pro tip: For an extra smooth syrup, strain out the pecan pieces after the syrup has cooled. You can save these flavor-infused nuts for garnish!
Step 3: Cool the Syrup
Allow the syrup to cool completely at room temperature (about 30 minutes). Transfer to an airtight container or bottle for storage. The syrup will thicken slightly as it cools.
Pro tip: Make a double batch and store it in a squeeze bottle for quick and mess-free coffee preparation all week long.
Step 4: Brew and Cool Your Coffee
Brew coffee at 1.5 times your normal strength. For even better results, cold brew coffee works exceptionally well in this recipe. Allow the coffee to cool completely.
Pro tip: Pour hot coffee over ice cubes in a heat-safe measuring cup to cool it quickly without diluting it too much.
Step 5: Assemble Your Butter Pecan Iced Coffee
Fill a tall glass with ice. Pour in your cooled coffee (about 1 cup). Add 3 tablespoons of your homemade butter pecan coffee syrup and stir well. Add your milk or cream and stir again.
Pro tip: For an extra decadent experience, use half-and-half or heavy cream instead of regular milk.
Step 6: Garnish (Optional)
Top with whipped cream and sprinkle with crushed toasted pecans for a picture-perfect finish that tastes as good as it looks.
Pro tip: A light dusting of cinnamon or a drizzle of caramel sauce takes this coffee to the next level!

- For brunch, serve alongside French toast or cinnamon rolls for complementary flavors.

Common Mistakes to Avoid
- Using weak coffee: The robust coffee flavor needs to stand up to the sweet syrup. Brew it strong!
- Adding syrup to hot coffee: This dilutes the flavors and melts your ice too quickly. Always cool your coffee first.
- Burning the pecans: Toasted pecans add tremendous flavor, but burnt ones will ruin your syrup.
- Skipping the butter extract: This ingredient makes a huge difference in achieving the authentic Dunkin’ flavor.
- Over-sweetening: Start with less syrup than you think you need – you can always add more!
Storing Tips for the Recipe
- Butter Pecan Syrup: Store in an airtight container in the refrigerator for up to 2 weeks. Warm slightly and shake before using if separation occurs.
- Make-Ahead Iced Coffee: Brew a large batch of strong coffee and store it in the refrigerator for up to 3 days.
- Complete Beverage: Best enjoyed immediately after preparation, as the ice will dilute the drink over time.
- Frozen Coffee Cubes: Pour cooled coffee into ice cube trays and freeze for future iced coffees that won’t become watered down.

Absolutely! The butter pecan syrup works wonderfully in hot coffee, lattes, or even stirred into hot chocolate for a nutty twist.
