What’s in the X-Treme Watermelon™?
The Official Smoothie King Version
The original X-Treme Watermelon™ blends strawberries, a watermelon juice blend, coconut water, and a protein boost for a sweet and light smoothie.
Our Homemade Copycat Version
My version uses frozen strawberries, fresh watermelon, and coconut water to nail the tropical vibe, plus a scoop of protein to make it more satisfying.
X-Treme Watermelon™ Ingredients
- Frozen Strawberries: 1 cup adds fruity sweetness and a naturally thick texture without needing much ice.
- Watermelon Chunks: 1 cup of fresh or frozen watermelon keeps it juicy, hydrating, and naturally sweet.
- Coconut Water: 1/2 cup brings in electrolytes and a light tropical taste that pairs perfectly with the fruit.
- Water: 1/2 cup helps everything blend smoothly and keeps it light—use more coconut water if you want extra flavor.
- Unflavored or Vanilla Protein Powder: 1 scoop adds a boost of protein to round out the smoothie.
- Ice (Optional): 1/2 to 1 cup of ice makes it extra cold and slushy, especially great on hot days.
How to Make the X-Treme Watermelon™ at Home
