1. Cinnamon Sticks
When looking at what truly constitutes the "best" on a list of overall highly favorable items, one has to consider a few base factors. It has to be universally beloved, but intimately enjoyed. It has to stand the test of time, but be relevant enough to continue to top off drive-thru orders. It has to have character, without overwhelming the rest of the meal. It has to be a compliment, while also being a standout. But ultimately, in the end, one has to go with their (now considerable) gut, too.
Perhaps the most "basic" entry on this entire list, Taco Bell's iconic dessert does more with a few basic ingredients than most fast-food purveyors do with an entire fridge full of corn syrup, food coloring, and crossover gimmicks.
The simplistic twists have a light dusting of cinnamon, an instantly identifiable crunch, and a ping-pong ball-level lightness -- which makes consuming them alarmingly easy, and infinitely enjoyable. And most importantly, they give Taco Bell denizens a dessert experience consummate with the rest of the menu: it's simultaneously a friendly callback to something you could vaguely identify as "Mexican" food, while being something entirely distinct. I'd call that a nuanced Taco Bell-ian flourish (as a compliment). It's top-five material on their entire menu. And No. 1 material in the dense, confusing, and more-often-than-not delicious world of fast-food desserts.
