Catch that campfire flavor in a cup! This copycat Starbucks S’mores Frappuccino recipe brings gooey marshmallow, rich chocolate, and buttery graham cracker goodness straight to your kitchen.

I am a big fan of coffee drinks. A simple cold brew, lattes of all kinds, iced coffee, and, of course, Frappuccinos – I love them all. Some days, I think caffeine might be the only thing keeping me going!

And some days just call for a fancy coffee drink. You know the kind: cold, creamy, and so over-the-top delicious that you actually forget you haven’t folded that laundry pile for three days. (Just me?)

One of my ultimate faves is the Starbucks S’mores Frappuccino, but since it’s a limited time offering and seems to disappear faster than a snack stash in a house full of teenage boys, I knew I had to crack the code to make it at home.

Supplies

Blender
Whisk/Hand mixer
Tall glass
Reusable straw

Ingredients

Toasted marshmallow syrup – This is what gives the drink that marshmallow-y flavor!
Heavy cream – This is needed to create the marshmallow whipped topping.
Ice – This gives your s’mores frappe that frozen, slushy vibe we all crave.
Whole milk – Adds that perfect creaminess; you can also use 1% or 2% if you prefer.
Vanilla syrup – Sugar-free is a great option too!
Instant espresso – The perfect hit of caffeine. Starbucks Via is our favorite.
Chocolate syrup – This Smucker’s brand is my favorite, but you can also find Torani and Ghirardelli syrups on Amazon.
Graham crackers, crushed – Gives the drink that unmistakable s’mores crunch and flavor.
Extra chocolate syrup – For the perfect finishing touch.

Instructions

1. In a bowl, make the marshmallow whipped cream by whipping the toasted marshmallow syrup and heavy cream together. Beat with a hand mixer or whisk until stiff peaks have formed. Set this aside for later.

2. Blend ice, whole milk, vanilla syrup, espresso powder, and chocolate syrup together in a blender until smooth.

3. Drizzle extra chocolate syrup around the inside of a large glass to get those signature Starbucks vibes.

4. Fill the bottom of the glass with some of the crushed graham crackers and a large scoop of the marshmallow whipped cream.

5. Fill the cup halfway with the blended Frappuccino mixture.

6. Repeat the layers, adding more graham cracker crumbs and another generous scoop of whipped cream.

7. Fill the cup with the remaining Frappuccino mixture.

8. As the finishing touch, add more marshmallow whipped cream, another chocolate drizzle, and one last sprinkle of graham cracker crumbles to the top of the drink. Enjoy!

Tip: For a healthier version, replace the vanilla and toasted marshmallow syrups with the sugar-free versions.

Tips and Tricks

To get an even more intense chocolatey flavor, add some cocoa powder to the milk mixture before blending.
Try mocha sauce instead of regular chocolate sauce if you love a deeper coffee flavor.
Mix a couple spoonfuls of marshmallow fluff into the whipped cream for an extra gooey kick.
If you want your Frappuccino thicker, add extra ice cubes. If it is too thick, add a little more milk or an espresso shot.
Swap in ice cream for a milkshake-style Frappuccino that’s pure dessert-level indulgence.
For a fun twist, top with an edible chocolate cookie straw.

Frequently Asked Questions

What’s the best way to crush graham crackers for this recipe?
Place them in a zip-top bag and crush them with a rolling pin until they resemble fine crumbs—perfect for layering and topping.
