Ingredients

Frappuccino Base

½ cup VERY strong coffee chilled (or 2 espresso shots)
¾ cup whole milk
1¼ cups ice
1½ tbsp milk chocolate sauce
½ tsp marshmallow fluff
1–2 tsp sugar or simple syrup to taste
½ tsp vanilla extract
Pinch of salt

Marshmallow Whipped Cream

½ cup whipped cream
2–3 tsp marshmallow fluff

Toppings

Chocolate drizzle
Graham cracker crumbs
Optional toasted marshmallows

Instructions

Blend the Frappuccino Base

Add the chilled coffee, milk, chocolate sauce, marshmallow fluff, sugar, vanilla extract, salt, and ice to a blender. Blend until smooth, creamy, and free of ice chunks.

Make Marshmallow Whipped Cream

In a small bowl, stir together the whipped cream and marshmallow fluff until smooth and lightly sweetened.

Assemble the Drink

Spoon a layer of marshmallow whipped cream into the bottom of a tall glass. Lightly drizzle chocolate sauce inside the cup. Pour the blended frappuccino over the cream.

Finish and Garnish

Top with more marshmallow whipped cream, chocolate drizzle, graham cracker crumbs, and optional toasted marshmallows.

Notes

☕ Use Strong Coffee for Best Flavor

For the best S’mores Frappuccino recipe, always use very strong chilled coffee or espresso. This prevents the drink from tasting watered down once blended with ice and helps replicate the bold coffee base of a Starbucks S’mores Frappuccino.

🍫 Choose Milk Chocolate for Authentic Taste

Milk chocolate sauce is essential for achieving that classic smooth, sweet s’mores flavor. Dark chocolate can make the drink too bitter and overpower the marshmallow notes.

🍬 Keep Marshmallow Flavor Balanced

Only a small amount of marshmallow fluff should be blended into the base. Most of the marshmallow flavor should come from the whipped cream topping to create a more authentic layered flavor experience.

🧊 Blend Just Until Smooth

To keep the frappuccino creamy and not icy, blend just until smooth. Over-blending can make the drink too thin, while under-blending leaves ice chunks. Serve immediately for the best texture.

🍪 Add Graham Crackers as a Topping

Graham cracker crumbs are best used as a topping rather than blended into the drink. This keeps their texture intact and delivers that signature s’mores crunch and flavor in every sip.

🔥 Toasted Marshmallows for Extra Flavor

For a stronger “campfire” taste, lightly toast marshmallows before adding them on top. This enhances the overall s’mores flavor and gives the drink a more authentic finish.

🥛 Easy Customizations

This homemade frappuccino is easy to customize. Skip the coffee for a kid-friendly version, adjust sweetness to your preference, or use dairy-free milk and whipped topping for a dairy-free alternative.
