Buc-ee's Beaver Nuggets

Buc-ee's Beaver Nuggets are the undisputed king of gas station snacks, outselling every other item on this list by a wide margin. These sweet, caramel-coated corn puff snacks are absurdly addictive—imagine Corn Pops that went to finishing school—and a single 16-ounce bag contains 2,000 calories, making it a fuel-efficient choice for the road. Buc-ee's sells over 10 million bags annually, enough to fill several Olympic swimming pools, and the chain's bathrooms are cleaner than most restaurants, cementing its status as a pilgrimage site for travelers across the South.
