What’s a Dot Cake? All About the Viral Dessert

The latest viral dessert has arrived right on the dot.

And it is aptly named the “dot cake.” If you hop on TikTok, you’ll find countless videos of influencers scraping their spoons across the sprinkled-covered surface before diving into the fluffy cake in a cup.

“I cannot go on my phone without seeing a video of a dot cake,” baker Alex Posner, who cofounded the bakery behind the sugary sensation—The Dot Cakes—on New York’s Long Island with her mom Sondra Posner—recently told Good Morning America, “which is extremely surreal.”

After all, Alex never expected the treats would become this popular when she started making them as a high school senior back in 2017.

“This was just a friends-of-friends thing,” she explained on the Invisible Ink podcast in 2024. “People liked the way they tasted, and they were cute. It just kind of was this whole packaged deal.”

But it was around her sophomore year of college that Alex’s customer base expanded, and she had her “aha moment” that she could turn this idea into a business. 

“I would have clients that were showing up to my house and showing up to the store where I just had no idea who they were,” the University of Texas at Austin alum continued. “I was like, ‘This has reached people that I didn’t even know existed, and I didn’t even know was possible.'”
