This Watermelon Cocktail Vodka Punch recipe is a take on the classic Cosmo cocktail with a refreshing twist. Instead of making individual servings, think ahead and save time by setting yourself up with a big batch, and enjoy the whole night with this refreshing cocktail and your friends.



  • 3 cups vodka
  • 3 cups watermelon juice
  • 1 cup fresh lime juice
  • 1/2 cup simple syrup (directions below)
  • Watermelon balls, for garnish


  1. Make the watermelon juice: place the watermelon pieces in a blender, and blend until smooth. Strain using a fine mesh strainer.
  2. Make the Simple Syrup: Combine 1 cup of white sugar and 1 cup of water in a small saucepan and bring to a boil. Cook, stirring, until the sugar dissolves. Remove from the heat and let cool completely. Makes about 1.5 cups.
  3. Make the Punch: Pour the vodka, watermelon juice, lime juice and simple syrup into a large pitcher, and stir.
  4. Serve in a hollowed-out watermelon or punch bowl, and pour into punch glasses or cocktail glasses with a ladle.


Keep the simple syrup covered in the refrigerator for up to 1 month.
