1. In a bowl, make the marshmallow whipped cream by mixing 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, and chocolate syrup together in a blender until smooth.

3. Making sure to use a large glass, prep your frappuccino cup by drizzling the sides with chocolate syrup to get the Starbucks S’mores Frapp look.

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, filling with graham cracker crumbs and whipped cream again.

7. Fill the cup the rest of the way full with frappuccino mixture.

8. As the finishing touch, add remaining marshmallow whipped cream, a drizzle of chocolate syrup, and another sprinkle of crushed graham cracker to the top of the drink. Enjoy!
