Give the whole thing a good shake and then strain into your coupe glasses.
Spiderweb Topping
Microwave the mini marshmallows for 20 seconds, or until soft.
1/2 cup mini marshmallows
Dip your fingertips into the soft marshmallow and spread the melted marshmallow around the rim of the glass, stretching from one side to the other. You can wet your fingertips with a little bit of water so it isn't quite as messy.
Heavy whipping cream is best here, so that the cocktail comes out nice and creamy. It's entirely doable to use milk, but you won't get the same results (color, texture, flavor). Half and half would be my recommendation if you don't have heavy cream on hand.
We opted for regular vodka, but you can easily substitute with marshmallow, vanilla, coffee, or caramel flavored vodkas.
