Starbucks Copycat S’mores Frappuccino

For the marshmallow whipped cream:

1. In the bowl of a stand mixer fitted with a whisk attachment, or using a hand mixer, beat the cold heavy cream on medium-high speed until soft peaks form.
2. Add the marshmallow fluff and vanilla extract, then beat again until stiff peaks form. Be careful not to overmix, or it might get clumpy.

For the chocolate sauce:

1. In a microwave-safe bowl, combine the milk chocolate and heavy cream. Microwave in 30-second intervals at 50% power, stirring between each interval, until completely melted.
2. Stir in the butter until the mixture is smooth.

For the ice-blended coffee:

1. In a blender, combine the chilled brewed coffee, milk, vanilla syrup, ice, and optional instant coffee or espresso powder. Blend until thick and smooth.

To assemble:

1. In a cup, start with a layer of marshmallow whipped cream at the bottom, followed by 2 tablespoons of chocolate sauce.
2. Pour in the ice-blended coffee, leaving some room at the top for more marshmallow whipped cream.
3. Sprinkle with graham cracker crumbs, and enjoy your homemade S’more Frappuccino right away!
