Ingredient Notes
The hot water and sugar are mixed first so the sugar dissolves fully and gives the slush a smoother texture. This step is important because undissolved sugar can make the final drink feel gritty instead of smooth.
Blue raspberry Kool-Aid is what gives the slush its bold fruity flavor and bright blue color. Using two packets makes the flavor strong and fun, especially once blended with all the ice.
Cold water helps balance the concentrated flavor mixture before blending, and the ice turns everything into that thick, frozen slush texture. If you want an even frostier result, adding a little extra ice is the easiest way to get there.
How to Make
1. Dissolve the sugar
In a bowl, pitcher, or large measuring cup, combine the hot water and sugar.
Stir well until the sugar fully dissolves. This creates the sweet base for the slush and helps the final drink blend more smoothly.
2. Add the cold water
Pour in the cold water and stir.
This cools the mixture down and gets it ready for the Kool-Aid and ice.
3. Mix in the Kool-Aid
Add the blue raspberry Kool-Aid packets and stir until fully combined.
Make sure there are no dry streaks left and the color looks bright and even throughout the mixture.
4. Add to the blender
Pour the Kool-Aid mixture into a blender, then add the ice.
Start with the 4 cups of ice listed, then adjust after blending if you want a thicker texture.
5. Blend until slushy
Blend on high until the mixture is thick, smooth, and icy.
If it looks too thin, add more ice and blend again. If it seems too thick to move well in the blender, add a tiny splash of water.
6. Taste and adjust
Taste the slush before serving.
If you want a slightly stronger flavor, you can add a little more Kool-Aid mixture. If you want it thicker, blend in more ice.
7. Pour into cups
Pour the slush into clear cups.
Clear cups are a fun choice because they show off the bright blue color.
8. Serve right away
Serve immediately with straws.
This slush is best while it is freshly blended, thick, and icy.
Tips for Best Results
Dissolve the sugar fully in the hot water before adding anything else. This makes a big difference in getting a smoother, better-textured slush.
Use cold water after that first step so the mixture is cooler before it hits the ice. That helps keep the final drink thicker.
Blend just until smooth and slushy. Overblending can warm the mixture slightly and make it thinner than you want.
Add extra ice slowly if you want a thicker texture. It is easier to make the slush thicker than to fix one that has become too diluted.
Serve it right after blending. Frozen slush drinks are always at their best when fresh because the icy texture softens as they sit.
Chill the cups first if you want the slush to stay frozen a little longer after serving.

It is especially fun for cookouts, birthday parties, pool days, or quick afternoon treats.
Storage and Reheating
- Best served: Immediately after blending
- Freezer: You can freeze leftovers and re-blend later
- Do not reheat: This is a frozen drink and should stay cold
If it starts melting, just add a little more ice and blend again to bring back the slushy texture.
Common Mistakes to Avoid
One common mistake is not dissolving the sugar fully. That can leave the drink gritty instead of smooth.
Another is adding too little ice. Without enough ice, the drink will taste good but feel more like juice than a true slush.
Using warm liquid in the blender can also make the ice melt too quickly, so make sure the Kool-Aid base is cooled down with the cold water first.
Finally, do not let it sit too long before serving if you want the best frozen texture.
