Why Costco’s Pumpkin Pie Sundae Works So Well
At first, the Costco pumpkin pie dessert hack might sound a little extra. But once you think about it, it makes perfect sense.
Costco’s pumpkin pie has long been a cult favorite. It’s huge, rich, and perfectly spiced, not too sweet, with that classic custardy texture. Pairing it with vanilla soft serve adds balance: cool, creamy, and just the right contrast to the warm pumpkin flavor.
The textures also work beautifully, the flaky crust, dense pie filling, and melting ice cream come together in a way that feels nostalgic and comforting. It’s like Thanksgiving dessert in a cup, but with Costco-level scale and affordability.
The Joy of Costco Food Hacks
The best part of any Costco trend is the joy people bring to it. This Pumpkin Pie Sundae isn’t a menu item, it’s a community creation. In one TikTok, a shopper builds it right in her car, layering soft serve over pumpkin pie into a melty masterpiece that instantly lit up the comments.
“That big ass pie was only $6?!” one person shouted. Another wrote, “It’s only $8 total? I’m doing this tomorrow.” Others chimed in with ideas, “This with a warm crumb apple pie 🤤.”
It’s a reminder that Costco isn’t just a store, it’s a culture. People love hacking it, sharing it, and turning everyday warehouse finds into viral comfort food moments.
