How to Make Blue Kool-Aid Slush

Step 1: Dissolve the Sugar

Add the hot water to a large cup, bowl, or pitcher.

Pour in the sugar.

Stir until the sugar fully dissolves.

This step is important because it helps the slush taste smooth and sweet instead of grainy.

Step 2: Add the Cold Water

Pour the cold water into the sweetened hot water mixture.

Stir well to cool the mixture down and balance the sweetness.

The cold water also helps the Kool-Aid mix evenly before blending.

Step 3: Add the Kool-Aid

Add the blue raspberry Kool-Aid packets to the water mixture.

Stir until the powder is fully dissolved and the liquid turns bright blue.

Make sure there are no dry powder clumps left in the bottom.

Step 4: Add Ice to the Blender

Place the ice into a blender.

Use about 4 cups of ice for a thick slushy texture.

If you want the drink even thicker, you can add more ice later.

Step 5: Pour in the Kool-Aid Mixture

Pour the blue raspberry mixture over the ice in the blender.

Make sure the blender is not filled too high.

If your blender is small, blend the slush in batches.

Step 6: Blend Until Slushy

Blend until the mixture becomes thick, icy, and smooth.

The texture should be like a frozen slush drink.

If it is too thin, add more ice and blend again.

If it is too thick, add a splash of cold water.

Step 7: Taste and Adjust

Taste the slush before serving.

If you want it sweeter, add a little more sugar or a splash of syrup.

If you want it more icy, add extra ice.

If you want a stronger blue raspberry flavor, add a little more Kool-Aid powder.

Step 8: Serve

Pour the slush into clear cups.

Clear cups make the bright blue color look even better.

Add straws and serve immediately while cold and icy.

This drink is best enjoyed right after blending.

Storage & Make-Ahead Tips

This Blue Kool-Aid Slush is best served immediately after blending.

If stored too long, the ice will melt and the texture will become more like juice.

To make it easier for parties, prepare the Kool-Aid mixture ahead of time and keep it in the refrigerator.

When ready to serve, blend the chilled mixture with ice.

You can also freeze the Kool-Aid mixture in ice cube trays, then blend the cubes with a little cold water for an even thicker slush.

Why This Recipe Works

This recipe works because the sugar dissolves first in hot water, which creates a smooth sweet base. The cold water cools the mixture down, the blue raspberry Kool-Aid adds bold flavor and bright color, and the ice blends everything into a thick frozen slush.

The result is a cold, sweet, colorful drink that is simple, refreshing, and perfect for warm days.

This Blue Kool-Aid Slush is cold, sweet, icy, and easy to make. It is perfect for summer days, BBQs, birthday parties, pool days, or anytime you want a quick frozen treat.
