Place the ice cubes into a blender, filling it halfway to allow space for blending.
Pour the chilled Gatorade over the ice, ensuring all the ice is covered for a well-blended slush.
Secure the lid on the blender and blend on high speed until the mixture reaches a smooth, granular slushie consistency—about 1 to 2 minutes. You should hear the ice breaking down and see a vibrant, icy mixture forming.
Stop the blender and check the texture—if it’s too icy or chunky, blend a few more seconds until evenly slushy.
Pour the slushie into glasses, revealing a bright, cold, and crunchy frozen beverage.
Serve immediately with a straw or small spoon, enjoying the refreshing, tangy burst of flavor and icy crunch.
