Dairy Queen is one of Warren Buffett's most famous businesses — he acquired it for almost $600 million in the late '90s.Decades later, it's still worth millions and is considered one of the leading dessert and snack chains in North America. And at the core of its success might be one of its signature desserts: The Blizzard, a frozen treat blended with all sorts of mix-ins.Blizzard flavors come and go, and I'm always hunting for the best one. So, since August 2020, I've been eating and ranking every Dairy Queen Blizzard I could get my hands on. Here's how the Blizzards I've tried so far stack up, ranked from my least favorite to my top pick. Editor's Note: Availability may vary. This list includes limited-edition and seasonal flavors that don't always return.

Cotton Candy Blizzard

The Cotton Candy Blizzard was too sweet for me.

For me, the first problem with this seasonal Blizzard was the texture. It had these chewy, colorful bits of sugar sprinkles that felt a bit off — like they weren't supposed to be there.However, the almost unbearable sweetness of this Blizzard is what earned it a spot at the bottom of my list. This dessert tasted like pure sugar to me, and my teeth still ache a bit thinking about it.I could picture younger kids absolutely loving this, but I can't see myself ordering this again.
