This easy Copycat Sonic Slushes recipe lets you recreate the refreshing, icy drink at home with just a few simple ingredients. Perfect for cooling down on a hot day, this slushie blends ice water, sugar, and flavored powdered drink mix into a smooth, sweet treat that’s ready in minutes. Customize it with whipped cream or cherries for an extra indulgent touch.

Ingredients

Slush Ingredients

  • 4 cups ice water (comprising 3 cups water plus ice to fill up to 4 cups)
  • ⅔ cup sugar
  • 1 tablespoon powdered drink mix (approximately 2 small packets)

Optional Toppings

  • Whipped cream
  • Maraschino cherries
  • Ice cream

Instructions

  1. Add ingredients to blender: Pour the ice water into your blender container first, followed by the sugar, and then the powdered drink mix. This order ensures even mixing without clumping.
  2. Blend until smooth: Set your blender on high speed and blend the mixture until you achieve a uniform, icy slush consistency with no visible granules of sugar or drink mix.
  3. Serve: Pour the freshly blended slush into your favorite drink cups immediately to preserve the icy texture.
  4. Add toppings (optional): For an indulgent twist, top your slush with whipped cream, a maraschino cherry, or a scoop of ice cream before serving.

Notes

  • Adjust sugar amount to your taste preference if you want it less or more sweet.
  • Use any powdered drink mix flavor you prefer to customize your slush.
  • To maintain the slush texture longer, serve immediately after blending.
  • If you don’t have a blender, finely crush ice and stir vigorously with the sugar and drink mix for a similar effect, though texture may vary.
