Starbucks Refreshers are delicious and, well, refreshing!, but they’re loaded with sugar. Thankfully, this keto copycat version tastes just as good as Starbucks but without all of the sugar and carbs!

This drink is inspired by the Starbucks Mango Dragonfruit Refresher, but with passionfruit tea instead because it’s deeelicious. I hope you enjoy it!

Why I Use and Love ChocZero

ChocZero is my favorite keto-friendly syrup and chocolate brand! They offer a wide variety of products from fruit syrup (like the mango syrup used in this recipe) to peanut butter cups to chocolate bark to chocolate syrup and more. Everything tastes amazing, is reasonably priced, and is high-quality.

  • 1 bag Tazo Passion Tea steeped in 10 oz water and chilled⁠
  • 2 tbsp ChocZero Keto Mango Syrup⁠
  • additional keto-friendly sweetener to taste (I added 1 1/2 tbsp Swerve Confectioners⁠)
  • 1 cup ice⁠
  • optional: 2 tbsp heavy whipping cream


  • Combine (using a blender for best results) tea, syrup, and additional sweetener.⁠
  • Pour over ice.⁠
  • If desired, add heavy whipping cream and give the mixture a quick stir. (You can blend it fully if you'd like, but I think it looks really fun when it's not completely mixed in.)⁠


  • Please note that while this drink is high in carbs, it is VERY LOW in NET carbs due to the high fiber content of ChocZero.
  • If you choose to add the heavy whipping cream, the nutrition facts are 168 calories / 11.2g fat / 0.6g protein / 2.8g net carbs.

    I recommend saving money on swerve confectioners and just get bulk Erythritol/monk fruit sweetener (4.50/lb at my store in Seattle Washington,USA) and run it through the coffee grinder.
    I buy that granulated and convert to powdered 2 lbs at a time, because erythritol has a tendency to get crunchy with anything you put in the fridge.
