A Fluffy Coke is simple to make. You line the inside of a glass cup with marshmallow fluff and then fill it with Coca-Cola. What happens after you make it on camera is, well, much more complex.
I made fluffy Coke for Annie's Cafe—a video series where I recreate the internet's favorite complicated, confectionary coffees. While a beverage consisting of soda and whipped marshmallow is, of course, not coffee, my version—which includes an oat milk cold foam and a splash of vanilla syrup—aligns with the series' spirit: It's sweet, drinkable, and trending online.
