Add marshmallow fluff to a tall glass: Use a spoon to scoop out ½ cup of marshmallow fluff and spread it around, coating the entire inside of the glass evenly. This step is crucial for ensuring the delicious marshmallow flavor permeates throughout the drink.
Fill the glass with crushed ice: Take your glass and fill it almost to the top with crushed ice, ensuring there’s a little space left to pour in your soda without overflowing.
Pour the Coke slowly: Open one can (12 ounces) of Coke and gently pour it over the ice. This slow pour helps create a layered effect and preserves the fizz.
Stir and serve: Give the mixture a gentle stir to combine the marshmallow fluff and Coke. For an extra fun twist, cover the glass with a lid and shake gently to mix everything together. Enjoy your cold, nostalgic drink immediately!
