                                According to nutritional data from beverage providers like Circle K and 7-Eleven, frozen versions of Mountain Dew, such as a Slurpee or Freeze, do contain caffeine, though often in a smaller quantity per serving than the canned soda. The freezing process does not eliminate the caffeine, a stable compound, which remains active within the icy beverage.
