Cookie Butter Cold Brew (Dunkin' Copycat)

All my Biscoff-loving buddies out there are going to flip for this DIY Dunkin’ Donut Cookie Butter Cold Brew recipe. With just 5 ingredients and 5 minutes of effort, you can make this dessert-inspired drink brimming with speculoos spices, caramelly brown sugar, and creamy cold foam. It’s even tastier than eating a spoonful straight from the jar!

While I usually focus on Starbucks copycat recipes, I’ve started to take a liking to Dunkin’. Maybe I’m late to the game—there aren’t really any by us—but once I tried the cookie butter cold brew and iced cookie butter latte, I knew we’d become fast friends. Who could resist a sweetened cold brew topped with a crown of cookie butter-flavored sweet cream cold foam? 

Not this java-loving mama. I mean, Biscoff Lotus cookies are easily the best thing about flying. And anyone who loves creamy Jif-style peanut butter is destined to fall for cookie butter. Combine them with boldly flavored cold brewed caffeine and creamy dairy and you’ve ticked off all my “crave” boxes.

But, while Dunkin’ tends to be slightly less premium-priced than Starbucks, you’re still looking at a minimum of $5 for a drink with tax. That’s fine for a splurge, but for a middle-class gal with two kids (and their college funds)? It’s not a sustainable habit. Luckily, I’ve cracked the code on how to make this cookie butter cold brew Dunkin’-style for dimes on the dollar.

What does it taste like?

My copycat cookie butter cold brew tastes like a frosty winter morning in a cup. It’s sweet but balanced, spiced but mellow, and buttery without being heavy. The cold brew brings a deep, smooth coffee base with natural chocolatey undertones, while the brown sugar syrup adds a warm caramel sweetness that softens the bold edges.

Then comes the star: cookie butter cold foam. It’s creamy, buttery, and spiced with hints of cinnamon, nutmeg, and caramelized brown sugar—like a Biscoff cookie turned into a cloud. The foam slowly melts into the coffee as you sip, creating a swirl of sweet, spiced cookie flavor in every drink. Yum!

Why You’ll Love This Dunkin’ Copycat Recipe

• Quick & Easy - You only need 5 ingredients and 5 minutes to make this bougie cold brew, making it doable even on busy mornings. It’ll take way less time than standing in line—plus you don’t have to tip at the end!
• Budget-Friendly - With the holidays on the horizon and prices rising everywhere I look, I’m always on the lookout for ways to save money. One of my favorites? Making Coffee Copycats at home! (Shocking, I know.) I get all the fancy café flavors I crave, but without the lingering guilt of forgoing frugality.
• Simple & Seasonal - Speculoos cookies always remind me of winter, when my grandma would put out a tray of warmly spiced windmill cookies. At the time I was hooked on milk, but the adults would always dip theirs in coffee. This lovely layered libation brings back all those nostalgic flavors and aromas in every sip!

Ingredients Needed

• Heavy Cream & Whole Milk - A decent amount of fat is necessary to get cold foam to whip into a lovely froth. This dairy duo is perfect!
• Brown Sugar Syrup - This simple syrup upgrade adds a caramelly warmth to both the cold foam and cold brew, mimicking the flavor of fresh-baked cookies.
• Cookie Butter Extract - The star of the show! It concentrates all the warmly spiced, sweet and creamy flavor of cookie butter into a potent liquid that melts seamlessly into cold coffee or sweet cream cold foam.
• Cold Brew Coffee - Rich, bold, smooth, and heroically caffeinated cold brew offers a less-bitter, more robustly flavored base than iced espresso or chilled conventional coffee.
• Ice - For keeping your cookie butter cold brew frosty to the last drop! Remember that larger ice cubes melt more slowly, so take that and your normal sipping speed into account before assembling your drink.

Substitutions

• Heavy Cream & Whole Milk - Slightly lighter whipping cream can stand in for heavy cream. You can also use half & half in place of whole milk and half of the cream. We’re looking for a mixture that’s roughly ⅔ cream and ⅓ milk. Hop down to the variations section for dairy-free alternatives.
• Brown Sugar Syrup - While it won’t make an exact dupe for Dunkin’ cookie butter cold brew, there are a few different options that would taste marvelous here. Toasted vanilla bean syrup, toffee nut syrup, sugar cookie syrup, or caramel syrup would be my top choices, but have fun experimenting.  
• Cold Brew Coffee - Feel free to use a few shots of iced French press espresso or strongly brewed conventional coffee that has been chilled.
• Ice - For a drink that gets darker as you sip, swap in coffee ice cubes. 

How To Make Dunkin Donuts Cookie Butter Cold Brew At Home

This easy copycat comes together in just a few simple steps:

Step 1: Add the cream, milk, brown sugar syrup, and cookie butter extract to a glass or frothing pitcher. 

Step 2: Froth FOam. Use a milk frother to whip it up until it’s light, airy, and velvety—think a dreamy, spiced cloud. Set it aside while you build your drink.

Step 3: Sweeten Cold Brew. Fill a tall glass with ice, then drizzle in the brown sugar syrup. This adds that deep, caramel sweetness that perfectly complements the bold coffee flavor.

Step 4: Pour & Stir. Add your cold brew to the glass and give it a good stir so the syrup and coffee mingle together. You should see the syrup disappear seamlessly into the coffee.

Step 5: Assemble & Enjoy. Spoon or pour the cookie butter cold foam over the top, letting it cascade down the sides. For the grand finale, sprinkle a few crushed Biscoff cookies on top—they add the perfect buttery crunch to each sip.

Optional Variations & Dietary Adjustments

• Dairy-Free/Vegan - Swap in your favorite non-dairy cream and milk alternatives. Vegan whipping cream or coconut cream and full-fat oat milk are my favorites!
• Sugar-Free - Use sugar-free syrup to keep the flavor without the calories. (My brown sugar syrup recipe offers instructions for making it at home!)
• Protein Cold Foam - Do a little Starbucks-Dunkin’ mishmash by adding unsweetened whey protein to your cookie butter cold foam.

Serving Suggestions

This cookie butter cold brew is brimming with cozy café energy. Enjoy it any time you need a little pick-me-up that feels like a treat. It’s perfect for slow fall mornings, afternoon work breaks, or as a sweet after-dinner coffee. 

In the morning or afternoon, pair it with better-for-you baked goodies like high-protein banana bread, oatmeal protein cookies or pumpkin protein muffins to play up those warm, spiced flavors while keeping your blood sugar in check. After dinner, lean into the sweetness with pumpkin pie crumble bars or chewy molasses spice cookies.

If you’re entertaining, serve it in clear glasses so everyone can admire the creamy cookie butter foam slowly swirling into the cold brew—it’s as pretty as it is delicious! For an extra indulgent touch, rim the glass with crushed Biscoff cookies and top it with whipped cream. I like to make a big batch of cold brew and a pitcher of the foam for an easy DIY brunch-bar setup.

Recipe Success Tips

• Use strong cold brew. The cookie butter foam is rich and sweet, so a bold, concentrated cold brew keeps the drink balanced and flavorful rather than cloyingly sweet.
• Chill your ingredients. Cold milk and cream froth up best—starting with cold equipment and ingredients ensures it gets perfectly fluffy.
• Don’t skip the cookie butter extract. It’s what gives the foam that authentic warm, spiced, and buttery Biscoff flavor. 
• Froth just until thick and silky. Over-frothing can make the foam stiff or bubbly. You’re aiming for a smooth, pourable texture that gently floats on top of the coffee.
• Layer for the best presentation. Pour the foam slowly over the back of a spoon so it sits beautifully on top of the cold brew.
• Add crushed cookies right before serving. Freshly crushed Biscoff cookies keep their texture and add the perfect buttery crunch to every sip.

DIY Dunkin Cookie Butter Cold Brew Nutrition

At about 212 calories per serving, this drink is more of a treat than a daily staple, but it’s still lighter than many coffeehouse options. Most of the calories come from the dairy and brown sugar syrup, which contribute roughly 11 grams of fat and 22 grams of sugar. The fat helps create a fluffy cloud-like texture, while the syrup provides sweetness and caramelly flavor.

Because it’s relatively low in sodium and protein, this drink fits best as an occasional indulgence rather than a meal replacement. If you’d like to enjoy it more often, try swapping in a low-sugar syrup to reduce the sugar and calorie load and/or consider making your cookie butter cold foam with added protein.

That said, as an RDN I always encourage clients to make space in their diets for fun treats. Being an adult is hard enough without food guilt, so enjoy your pleasures and just make smart, balanced choices throughout the rest of your day. Enjoy every slurp-worthy sip!
