Dunkin’ Butter Pecan Syrup Recipe (Copycat)
A rich, buttery, nutty coffee syrup made with real toasted pecans, brown sugar, and vanilla. This homemade version recreates Dunkin’s iconic seasonal flavor with deeper aroma, caramel-like sweetness, and authentic pecan richness—perfect for coffee, lattes, and desserts.
Ingredients
- 1 cup raw pecan halves
- 1 cup brown sugar packed
- ½ cup white sugar
- 1 cup water
- 2 tablespoons unsalted butter
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- Optional for stronger flavor
- ¼ teaspoon butter extract
- ¼ teaspoon pecan extract
Instructions
- Toast pecans in a dry pan over medium heat for 3–4 minutes until fragrant; roughly chop.
- In a saucepan, combine water, brown sugar, and white sugar; heat until fully dissolved.
- Add butter, salt, and toasted pecans; stir and bring to a gentle simmer.
- Simmer on low for 10–12 minutes to infuse flavor (do not boil hard).
- Remove from heat and let rest for 20 minutes.
- Strain through a fine mesh strainer, pressing lightly to extract liquid.
- Stir in vanilla and optional extracts once slightly cooled.
- Cool completely before transferring to a jar or bottle.
Notes
Toasting pecans is essential for authentic nutty flavor.
Use both brown and white sugar for balanced caramel sweetness.
Do not skip the resting (infusion) time.
Refrigerate up to 2 weeks; shake before use.
Substitute butter with 1 tablespoon neutral oil if needed (flavor will be lighter).
Great for coffee, lattes, cold brew, milkshakes, pancakes, waffles, and oatmeal.
