Some recipes arrive from memory before they ever reach the glass.
There is something about toasted marshmallow and chocolate that feels timeless — the sort of flavour that belongs equally to late summer evenings and quiet afternoons at home. I still think about those early moments in the kitchen: the warmth of something sweet slowly coming together, the anticipation of that first taste, and the way simple ingredients could somehow feel indulgent and unforgettable.
That feeling inspired this drink.
This S’mores Frappé takes everything nostalgic about the classic fireside treat and transforms it into something cooler, richer, and a little more refined. Deep coffee notes meet silky chocolate, while toasted marshmallow brings a soft caramel warmth that lingers long after the final sip. Finished with cream and a touch of texture, it feels less like a drink and more like a small occasion.
Perfect for slow mornings, warm afternoons, or those evenings when dessert deserves to be poured rather than plated.
Why You’ll Love This S’mores Frappé
This is comfort with a little ceremony.
The richness of coffee balances the sweetness beautifully, creating a drink that feels indulgent without becoming overwhelming. Toasted marshmallow adds warmth and depth, while blended ice gives it that velvety, cloud-like finish.
It feels luxurious, yet comes together effortlessly — no specialist equipment, no complicated techniques, just a handful of ingredients and a few quiet minutes in the kitchen.
The Journey to the Glass
Creating this frappé is less about following steps and more about layering flavour.
From brewing the coffee and blending the chocolate to introducing that unmistakable toasted marshmallow character, each stage builds towards something that feels familiar and entirely new at once.
Cold, creamy, smoky, and just indulgent enough — this is the kind of recipe that turns an ordinary afternoon into something worth lingering over.

What You’ll Need
A handful of simple ingredients come together here to create something far greater than the sum of its parts — rich, cool, velvety, and unmistakably reminiscent of toasted marshmallows and melted chocolate by the fire.
-
240ml cold brew coffee — smooth, bold and chilled, bringing depth and gentle bitterness to balance the sweetness
-
120ml whole milk (or your preferred alternative) — for a silky, creamy body
-
60ml double cream — adds richness and that indulgent dessert-like finish
-
2 tbsp chocolate mocha sauce — dark, glossy and deeply chocolatey
-
2 tbsp crushed digestive biscuit crumbs — for that buttery toasted note inspired by classic s’mores
-
1 tbsp marshmallow crème — soft sweetness with a subtle toasted vanilla character
-
A generous handful of ice — blended until smooth and velvety
To Finish
-
Extra biscuit crumbs for a delicate golden dusting
-
Marshmallow whipped cream for a cloud-soft finish worthy of dessert
Optional, but highly recommended: finish with a light drizzle of warm chocolate sauce or briefly toast the topping for a subtle campfire aroma.
Method
This is less about making a drink and more about building layers of flavour — cool coffee, rich chocolate, toasted sweetness, and a finish that feels unmistakably dessert-like.
Step One — Create the Frappé Base
Add the cold brew coffee, milk, double cream, crushed biscuit crumbs, and a generous handful of ice to a blender.
Blend until completely smooth and velvety. The mixture should become thick, creamy and lightly aerated — cold enough to refresh but rich enough to feel indulgent.
Step Two — Build the Chocolate Layer
Drizzle the chocolate mocha sauce around the inside and base of your serving glass.
Allow it to pool naturally rather than stirring immediately — this creates ribbons of chocolate throughout the drink and gives every sip a little extra richness.
Step Three — Pour & Layer
Slowly pour the blended frappé into the prepared glass.
As the cold mixture meets the chocolate, soft marbled layers will form naturally — the sort of detail that makes a homemade drink feel quietly luxurious.
Step Four — Prepare the Marshmallow Cream
In a chilled bowl, whisk the cream until softly whipped.
Fold through the marshmallow crème until smooth, glossy and cloud-like. You’re looking for soft peaks rather than stiffness — light enough to sit beautifully over the drink.
Step Five — Finish Generously
Spoon or pipe the marshmallow cream over the top.
Don’t be restrained here — this is where the drink transforms from iced coffee into something that feels unmistakably like dessert.
Step Six — Add the Final Touch
Scatter over a finishing dusting of biscuit crumbs.
For extra theatre, drizzle with a little more chocolate sauce or lightly toast the top for a subtle fireside aroma.
Serving Suggestions
Serve immediately while the frappé is at its coldest and the topping still feels impossibly soft.
It pairs beautifully with:
-
warm chocolate brownies
-
salted popcorn for contrast
-
soft cookies fresh from the oven
-
a thin slice of dark chocolate cake
Equally suited to slow summer afternoons or served as a dessert course when coffee feels too ordinary.
Make It Your Own
This recipe welcomes a little creativity.
-
Add a splash of vanilla bean extract for extra warmth
-
Blend through dark chocolate pieces for added texture
-
Stir in a spoon of hazelnut or almond butter for a richer finish
-
Swap part of the coffee for espresso for deeper intensity
-
Finish with a pinch of sea salt flakes to amplify the chocolate notes
No two versions ever taste exactly the same — and that’s part of the charm.
Notes, Variations & Little Luxuries
This frappé is wonderfully adaptable and rewards small changes.
For a dairy-free version, replace the double cream with coconut cream and choose your preferred milk alternative. Coconut brings a subtle richness that works beautifully with both the chocolate and toasted marshmallow notes.
If cold brew isn’t on hand, a homemade coffee concentrate or strongly brewed coffee that has been thoroughly chilled will deliver a deeper, more intense finish.
Sweetness is entirely personal — and this recipe leaves room to make it your own.
For a richer, more dessert-like result, add an extra spoonful of chocolate sauce. For a softer, sweeter finish with more of that nostalgic toasted character, increase the marshmallow crème slightly and blend again until silky.
A small adjustment can completely change the personality of the drink — from elegant coffee-house refreshment to full dessert-in-a-glass indulgence.
