Ingredient Notes
Using three different Kool-Aid colors helps create the rainbow look and makes the final drink more exciting once the cubes are mixed together. Red, yellow, and blue work especially well because they are bright and instantly recognizable in the glass.
Domino Sugar sweetens the Kool-Aid mixture and helps make the cubes taste more like a fun party drink instead of flavored ice. Water keeps the recipe simple and lets the colors stay bright and clear once frozen.
Sprite is a great serving option because it is fizzy, clear, and sweet enough to pair well with the fruity cubes. It also helps show off the color-changing effect as the cubes melt.
How to Make
1. Mix the Kool-Aid
In three separate pitchers or bowls, mix each Kool-Aid packet with 1/3 cup Domino Sugar and 2 cups water.
Stir well until the sugar is fully dissolved and each mixture looks bright and smooth.
2. Pour into ice cube trays
Carefully pour the red, yellow, and blue Kool-Aid mixtures into standard ice cube trays.
Keep the colors separate so the cubes freeze into solid bright blocks of color.
3. Freeze overnight
Place the trays in the freezer and freeze overnight, or until completely solid.
This gives the cubes time to freeze fully so they hold their shape nicely in the drink.
4. Fill the glass
Once frozen, pop the cubes out of the trays.
Fill a large clear drinking glass with a mix of the red, yellow, and blue cubes.
5. Add the Sprite
Pour cold Sprite over the rainbow ice cubes.
As the cubes melt, the drink slowly changes color and becomes fruity, fizzy, and fun to watch.
6. Serve immediately
Serve right away with a straw.
The color effect is best while the cubes are still frozen and the drink is fresh and bubbly.
Tips for Best Results
Use clear glasses so the colorful cubes really stand out and the melting effect is easy to see.
Freeze the cubes fully before serving. Softer cubes melt too quickly and do not give the same bright party look.
Chill the Sprite before pouring so the cubes melt more slowly and the drink stays cold longer.
Mix the sugar thoroughly into each Kool-Aid pitcher so the cubes freeze evenly and taste smooth.
Use separate trays if possible to keep the colors bright and distinct.
For the prettiest presentation, add a balanced mix of all the colors to each glass.

They are especially fun for birthdays, summer celebrations, and kid-friendly parties.
Storage and Reheating
- Freezer: Store the ice cubes in a freezer-safe container or bag after freezing
- Best served: Straight from the freezer in cold Sprite
- Do not reheat: This is a frozen drink add-in
- Best tip: Keep colors separated until serving if you want them to stay especially bright
These cubes can be made ahead, which makes them really handy for party prep.
Common Mistakes to Avoid
One common mistake is not dissolving the sugar fully. Undissolved sugar can settle and affect the flavor of the cubes.
Another is using cloudy or dark drinks to serve them in. Clear Sprite works best because you can actually see the colors.
Not freezing the cubes long enough can also make them melt too quickly and lose their effect.
Finally, using too few cubes in a large glass can make the color effect less dramatic, so filling the glass generously works best.
