Ingredients

  • Sour blue drizzle (recipe below)
  • ¾ cup whole milk
  • 3 tablespoon mango syrup
  • 1 tablespoon vanilla syrup (store-bought or homemade with recipe in notes)
  • 2 teaspoon dragonfruit powder
  • ¼ teaspoon xanthan gum (optional for thickening Frappuccino- can substitute with cornstarch, but use a little bit more)
  • 1 cup ice
  • Pink food coloring optional for more vibrant color
  • Whipped cream for topping
  • Pink and blue sanding sugar for topping

Blue Sour Drizzle

Instructions

  • Using a spoon, drizzle blue sour drizzle in swooping lines in the inside your glass, all the way around.
  • Add milk, mango syrup, vanilla syrup, dragonfruit powder, xanthan gum (or corn starch), and ice to blender and process until smooth and frothy. If you want a more vibrant pink Frappuccino, add a few drops of pink food coloring and blend to combine.

  • Pour the pink base slowly down the center of the glass so the blue drizzle stays on the walls of the glass.
  • Top the Frappuccino with whipped cream and dust half the whipped cream with a pinch of pink sanding sugar and half with blue sanding sugar. If you prefer, you can use pink pitaya powder blue spirulina instead of sanding sugars.

Blue Sour Drizzle

  • Put the white mocha sauce in a small bowl. Whisk in blue spirulina powder, citric acid, and blue raspberry extract until fully combined.

Notes

  • Instead of making blue sour drizzle with white mocha sauce, you can also use melted white chocolate. Simply melt ¼ cup chopped white chocolate or chocolate chips with 2 tablespoon heavy cream in 15-second microwave bursts, stirring between each, until smooth. Let it cool for about 10 minutes until thickened but still pourable. Whisk in blue spirulina powder, citric acid, and blue raspberry extract.
  • If you want to make your own vanilla syrup, you can do so with my homemade vanilla syrup recipe.
  • If you don't want to make or buy vanilla syrup,  you can replace it with an additional tablespoon mango syrup.
