  • 1 small watermelon cubed
  • 3 oz white rum
  • 3 limes juiced
  • 15 mint leaves muddles
  • 15 mint leaves fresh
  • 1 tablespoon powdered sugar
  • 2 cups ice

For Serving:

  • Ice
  • Mint leaves
  • Lime slices


  • Use fully ripe watermelon for mojito recipe. Remove the sweet, pink flesh of watermelon.  We did not bother to remove the seeds. Blend it and strain it in fine mesh sieve. Saves so much time.
  • Use high power blender or food processor to juice watermelon cubes. Strain the juice, pour into glass jar and refrigerate until use.
  • Use citrus squeezer to extract lime juice. Refrigerate it. If you like slushie watermelon mojito, freeze lime juice.
  • For sweetener you can use simple syrup or sugar. To make simple syrup boil ½ cup sugar in ½ cup water. Once sugar dissolves, remove from heat and let it cool completely.
  • Muddle 15-20 mint leaves. Smash it well so all natural oil and flavors of mint is released. Do not puree mint.
  • Use a glass pitcher to stir everything. Or use a cocktail shaker.
  • Into a pitcher add powdered sugar or simple syrup which ever you are using. Pour squeezed lime juice. Add in ice. Using a wooden cocktail stirrer stir until sugar is completely dissolved.
  • Next add muddled mint, lime slices, watermelon juice, white rum. For extra flavors add some more fresh mint leaves, few cubes watermelon (I froze watermelon cubes and added it. But the time you serve this mojito, frozen watermelon cubes will soften and make the mojito much cooler).
  • Stir everything together and while stirring smash mint and lime to release some of it’s fresh flavors into the mojito.
  • Refrigerate it until ready to be served.
  • Into mojito glasses, add few extra ice, some lime slices and pour watermelon mojito into the glasses.
  • Garnish with fresh mint leaves and serve immediately.
