What is ‘fluffy Coke’? Sugary drink dubbed ‘diabetes in a cup’ is the hottest beverage of the summer

A bizarre beverage combining marshmallow fluff and Coca-Cola is taking TikTok by storm, with sweet-toothed soda lovers championing the drink.

Dubbed “fluffy Coke,” the sugary concoction combines the creaminess of marshmallow with the crispiness of an ice-cold fizzy drink.

Content creator Emma Grace and her grandma, lovingly referred to as “Memama,” seem to be the masterminds behind the trend, taste-testing the drink on viral video and giving it a 10 out of 10 score for taste.

Using a spatula, the pair slathered marshmallow fluff on the interior of the glass and added ample ice cubes, before pouring in a regular can of Coca-Cola.

“I could drink like four of these,” Emma Grace said in the clip, which has garnered 3.7 million views.

Swearing the concoction is absolutely delicious, the pair inspired fellow TikTokkers to try it themselves, with hundreds of videos flooding the tag #fluffycoke .

In an attempt to switch up the recipe, some users have swapped regular Coca-Cola for diet , while others have traded it for Pepsi, root beer, Dr. Pepper , flavored sparkling water and even coffee .

One creative foodie even made a roasted marshmallow iteration of the drink, which involved browning marshmallows to put inside the drink.

“Ok, I can get on board with this trend,” creator Jessica Barstow captioned her clip of trying a fluffy Coke Zero.

“It just tastes like sweet Coke,” content creator Armin Arshe explained in a TikTok video .

Despite dessert lovers’ claims of the drink being “ so good ,” other taste testers weren’t convinced.

On X, critics called the trend “ overrated ,” arguing that it “ruins” the crispy bubbliness of soda . Meanwhile, on TikTok, gobsmacked users couldn’t fathom adding more sugar — from the fluff — to full-sugar cola, and creator Hannah Crump claimed it was a “waste of $4,” saying the dessert-like drink was “not it.”

“Adding sugar to Coke is CRAZY,” one user commented on a TikTok video .

“That sounds way too sweet lol,” another person wrote online .

“I felt this video impact my blood sugar,” quipped someone else.

“This is like diabetes in a cup!!” one person said.
