Pour the Kool Aid packet into a mixing bowl and add the sugar, stirring until fully dissolved.
1 packet Kool Aid flavor packet, 1 cup sugar
Slowly pour in the cold water while whisking gently to combine everything into a bright, uniform liquid.
2 cups cold water
Transfer the mixture to a shallow freezer-safe dish or a large resealable bag.
Place the dish or bag flat in the freezer and let it freeze for about 2 to 3 hours, occasionally checking and stirring with a fork every 30 minutes to create a slushy texture.
Once the mixture has become thick and slushy, use a fork to scrape and fluff it up, ensuring even icy texture.
Scoop the Kool Aid slushie into glasses, and enjoy immediately for a cool, colorful treat.
