Ingredients

  • Marshmallow whipped cream (recipe below or store-bought)
  • 2 tablespoon milk chocolate sauce*
  • ¾ cup whole milk
  • ¼ cup espresso or strongly brewed coffee cooled (omit if you prefer)
  • 2 tablespoon marshmallow or vanilla syrup
  • 2 graham cracker squares (optional for more graham flavor)
  • ¼ teaspoon xanthan gum (optional for thickening Frappuccino- can substitute with cornstarch, but use a little bit more)
  • 1 cup ice cubes
  • Graham cracker crumbs for topping

Marshmallow Whipped Cream

  • ½ cup heavy cream
  • 1 tablespoon marshmallow syrup
  • ¼ teaspoon cream of tartar (optional for stabilization)

Instructions

  • Put a small layer of marshmallow whipped cream on the bottom of your cup (about ¾ inch). Top with about 2 tablespoons milk chocolate sauce.
  • Add milk, espresso/coffee, marshmallow or vanilla syrup, graham crackers (if using), xanthan gum (if using), and ice to blender and process until smooth and frothy.
  • Pour Frappuccino into cup and top with marshmallow whipped cream (pipe it on or spoon it on) and graham cracker crumbs.

Marshmallow Whipped Cream

  • In the bowl of a stand mixer with whisk attachment or in a medium bowl with a hand mixer, beat together heavy cream, cream of tartar (if using), and marshmallow or vanilla syrup on medium-high speed until stiff peaks form, about 4-5 minutes. If not using immediately, store in fridge.

Notes

*I recommend using the milk chocolate sauce linked or similar. You can also feel free to make your own. You can use Hershey's chocolate sauce in a pinch, but it's a bit thinner and sweeter than what Starbucks used.
Other Tips:
  • When Starbucks brought back their S'mores Frappuccino, they skipped the graham cracker syrup in the base and used vanilla syrup instead. If you want the graham flavor, add a couple graham cracker squares into the blender when you're blending the drink. You can also feel free to add a layer of graham cracker crumbs over the chocolate sauce layer.
  • Starbucks used vanilla syrup in the second rendition of their Frappuccino, but if you already have marshmallow syrup, I recommend using that instead to enhance the s'more flavor!
  • The S'mores Frappuccino was a layered drink, but if you prefer, you can add the chocolate sauce into the Frappuccino mixture along with a little extra marshmallow syrup instead of layering.
