Ingredients

Scale

Slush Ingredients

  • 4 cups ice water (start with 3 cups of water and add ice until the total volume reaches 4 cups)
  • ⅔ cup sugar
  • 1 tablespoon powdered drink mix (approximately 2 small packets)

Instructions

  1. Add Ingredients to Blender: Place the ice water, sugar, and powdered drink mix into the blender in that order to prepare for blending.
  2. Blend Until Smooth: Blend the mixture on high speed until the texture is smooth and slushy, with no large ice chunks remaining.
  3. Serve the Slush: Pour the blended slush into your favorite drink cups, ready to enjoy immediately for the best icy texture.
  4. Add Toppings (Optional): For extra indulgence, top your slushes with whipped cream, cherries, or a scoop of ice cream to mimic Sonic’s signature style.

Notes

  • Adjust the sweetness by increasing or decreasing the sugar according to your taste preference.
  • Use any flavor of powdered drink mix to customize your slush flavor.
  • Serve immediately for the best texture; slushes can melt quickly if left out too long.
  • For a thicker slush, add more ice and blend longer.
  • These slushes are best consumed cold and fresh but can be stored in the freezer briefly and re-blended.
