  • high-speed blender


  • 2 cups watermelon packed, black seeds removed
  • cup peeled cucumber chunks
  • 1 tbsp chia seeds
  • 1 scoop collagen powder unsweetened. I like Vital Proteins
  • ½ cup filtered water not sink water
  • 2 tbsp sunflower seed butter salted. I like Sunbutter & Trader Joe's
  • 2 tbsp avocado heaping, ripe
  • 2 tbsp coconut butter
  • ½ cup ice


  • Add all the ingredients in order of appearance into a highspeed blender, water first for a Vitamix, water last for a Nutribullet.
  • Blast till well blended. Pour into 1 or 2 cups over ice, and freeze for 10 minutes.
  • Once ready serve with a straw, and try not to get brain freeze.


Nutrient information of the cucumber is from Healthline // You can always use plant-based milk if you don’t want to use water, just make sure it is unsweetened // This smoothie is best on the rocks (over ice) // White watermelon seeds are okay to consume, but you must remove the black seeds as they are toxic to consume // If you don’t like Sunbutter or are allergic, feel free to use almond butter. // Too much cucumber?  Add more watermelon // Too sweet?  Add more cucumber.
