To a blender, add espresso, chocolate syrup, marshmallow crème, milk and ice. Blend well until smooth.
Drizzle chocolate sauce inside of a glass. Pour in the frozen mixture.
Top with whipped cream.
Garnish with graham cracker crumbs, chocolate shavings and a toasted marshmallow, if desired. Serve with a straw.
Notes
Here are some tips and tricks for making this recipe:
Be sure to use milk, not heavy cream, as the blender will whip the cream and make your frappuccino too thick.
Make your own whipped cream. It’s truly so good! If you want to make your drink more like Starbucks’ add a little bit of marshmallow cream while you whip it.
Prepare all your toppings before blending the frappuccino. This way the drink mixture won’t melt while you fiddle with crumbling graham crackers, charring marshmallows or cutting chocolate.
