Emma Grace Burke and her grandmother, Memama on TikTok, love trying new trends. So, they made the fizzy, fluffy drink.
"My mom saw someone trying a fluffy Coke and thought it would be fun for my grandmother and me to try," Burke, from Florida, told Fox News Digital.
"And Fluffy Coke was such a fun name, we had to try it!" she added.
The mix of Coca-Cola and Marshmallow Fluff turned out delicious. It combines fizz and cream.
"You line your glass with Marshmallow Fluff, add ice and Coke, stir, sip, and enjoy!" Burke explained.

Burke suggests scraping the cup's sides to get Marshmallow Fluff in every sip.
The fluff makes the Coke foam even more, creating the "fluffiness."
"At first, it tasted like regular Coke, but stirring and scraping marshmallow transformed it," Burke said.
TikTok users enjoy personalizing the drink with their favorite sodas.
Others use Diet Coke, Dr. Pepper, or orange soda for a dreamsicle flavor with Marshmallow Fluff.
