Homemade Cookie Dough Coffee Syrup


I’ve developed a slight iced coffee addiction this past summer. It’s funny because, a year or two ago, I would’ve never touched the stuff. But over time, I eased into the world of hot coffee, and then splashed right into iced coffee this summer. Now, I don’t even want hot coffee anymore. All I want is ice, ice baby.

Sorry, I couldn’t resist.

The problem with iced coffee is that it’s a bit more of a pain to make at home. It’s not hard; it’s just not instantly gratifying like hot coffee is because you have to wait hours and hours for it to chill. The only way to instantly curb an iced coffee craving is to go to a coffee shop, which I have been giving into a lot lately.


I’ve taken a liking to the ice cream flavors at Dunkin Donuts, but that stuff is over-priced, and it adds up if you’re buying one every day. Instead, I’ve started planning ahead and making iced coffee ahead of time. Then, to get the fun flavors, I decided to give Homemade Cookie Dough Coffee Syrup a go.

Turns out, it’s the easiest thing on the planet. I bet you’ve got the ingredients on-hand right now. Just whip up a simple syrup and whisk in the identifying flavors of cookie dough (brown sugar, vanilla, and chocolate). That’s all you’ve got to do.

It’s uncanny how much this easy homemade coffee syrup really tastes like chocolate chip cookie dough. When I swirled it into my coffee and took a sip, it felt like I was sitting in a fancy café drinking a $5 coffee. I’m so fancy!

And you can be too.


A Few Tips Before You Get Cooking:

  1. Pay attention to the directions to stir and reduce heat, or you’ll wind up with a pot of burnt sugar.
  2. This works in hot or iced coffee.
  3. You can buy a cute little olive oil dispenser to store this syrup in. I just used an old bottle.
  4. Homemade Coffee Syrup makes a great gift.
  5. Break this out at a party or get-together, and look the fanciest son-of-a-gun on the block.

  1. Looks delicious! My favorite of the Dunkin’ ice cream flavors is the butter pecan. Any ideas on how to recreate that?

  2. i made a brown sugar iced coffee syrup too! great minds… :) how do you make your iced coffee? i’ve recently discovered the joys of making a batch in the french press…it’s so easy and can be made the night before. love it. i’ve been making it all summer and want to blog about my method soon!

    • Ha you’re so right! I just brew up a pot in the coffee maker, let it cool to room temperature, then refrigerate it until I’m ready to drink it and add some ice. Nothing fancy!

  3. How does this compare to D&D cookie dough? That was my favorite and they discontinued it. I am so irritated!! :) Going to try this though for sure!

  4. Im.SO happy I found this! I’m pregnant and the only thing I crave is cookie dough iced coffee! You made my day. Is it comparable to D&D?. I need to make iced coffee your way too :)

  5. As a full time pre med student with a part time job and part time hours shadowing doctors I want to extend a heart felt THANK YOU! I became addicted to this flavor at dunkin. To the point that I no longer like any other flavor. Once they took it away I was devastated. How else would I manage my insane schedule without my fix? The instant sugar high, the lasting caffeine buzz….it was perfect. You just saved my education.

  6. Do we need to add anything else to the coffee once we add this? Also, about how much of the syrup do we need to add per cup of coffee? Thanks!

    • It all depends on your preference. Some people prefer coffee with milk or cream to smooth it out. And the amount of syrup also depends on how sweet you like it. I recommend starting with 1 tsp. then adding more until it tastes how you like.

  7. Just got done making this!! Just waiting for my coffee to brew :)
    I was super obsessed with the DD one but I looked up how many carbs it has and
    It scared me away!! At least if i make it here I can control how much I use!

  8. I’m so excited to try this! Came across your recipe while looking for the dunkin donuts sugar cookie diy creamer. Do you have the sugar cookie recipe by chance? :)
