DIY Dunkin Donuts Butter Pecan Iced Coffee

DIY Dunkin Donuts Butter Pecan Iced Coffee

People in New England love their DD (Dunkin Donuts). At least where my sister lives in New Hampshire the DD’s outnumber Starbucks about 5 to 1. It’s a good thing that I don’t’ live in America right now because I am a little addicted to the coffee at Dunkin Donuts. I love their pumpkin syrup. When I went this spring I had numerous cups of their Baskin Robbins line, namely the Butter Pecan Coffee.

The only thing that I don’t like is that each Dunkin Donuts seems to interpret how much syrup is really necessary (usually it’s too much). I also seriously doubt that their coffee syrup has any trace of real pecans in it!

My DIY Starbucks Vanilla Spice Latte is one of my most popular posts so I decided to make my own version of the syrup using all real ingredients. Butter Pecan is a brown sugar cake with pecans and caramel tones. I soaked roasted pecans in water and sugar to try and infuse a nutty essence. I used a little brown sugar to add caramel tones. At the very end I whisked in a small amount of butter and caramel to complete the flavor.

Use the syrup in hot or cold coffee.

DIY Dunkin Donuts Butter Pecan Iced Coffee

Yield: 1 jar of syrup

DIY Dunkin Donuts Butter Pecan Iced Coffee



1/2 cup pecans

1 cup water

1/2 cup granulated sugar

1/4 cup light brown sugar

1 tbs unsalted butter

1 tbs caramel sauce (I used bonne maman)

iced Coffee

1-2 tbs syrup (or to taste)

1 cup filtered black coffee

2 cups ice cubes


  1. Preheat the oven to 350 F/180 C and place the pecans on a baking tray. Roast for 5 minutes until fragrant.
  2. In a small saucepan over low heat combine the water, both sugars and the toasted pecans. Leave to soak for 5 minutes. Increase the heat to medium and bring to a simmer. Stir for 5 minutes until the syrup is slightly reduced. Remove from the heat and whisk in the butter and caramel until completely melted and blended.
  3. Pour into a sterilized glass jar. Leave in the refrigerator overnight to let the flavors develop. Strain through a fine mesh sieve or cheesecloth in the morning (if necessary).
  4. To make an iced coffee pour one cup of hot filtered coffee over a glass with 1 cup of ice. Top up with more ice cubes. Shake the jar well before each use.

    Thank you very much for this! Dunnkin Donuts doesn’t carry this one anymore, so I have been seeking a new way to make it myself and you just gave it. :) Thanks so much. I’m also from New England (Massachusetts.) Stopped by Dunkin Donuts recently for the Butter Pecan and :( they stopped selling it.

    Hope you are enjoying London! Visited there only once and never got that fine country out of my mind. It’s just beautiful!! :)

  2. Do the pecans dissolve? Or do you leave them in or strain them out?

    • I left the pecans whole in the jar and then strained them out the next day. I wanted to try and let the flavors infuse over night.

    Does the toasting have some purpose other than adding flavor? I am only curious because I have ground pecans left from another recipe that I am thinking of using to make the Butter Pecan syrup, but not sure how well they will toast? Do you think it will work without toasting?

    • The toasting is to try and add a deeper nutty flavor. I would try toasting them in a pan on the stove over low to medium low heat. It might work. Depends how fine the pecans are ground.

        Alright, I’ll give it a go and see how the ground pecans work. And if not, off to the store I go for whole pecans! We live far enough from our nearest Dunkin Donuts that I can only have it on the weekend, so I would love to have this syrup at home.

    Sounds delicious. Can’t wait to try!

  5. So I’m super new to cooking, but what should the final consistency be? Mine is super thick and when refrigerated becomes hard.
