Start by measuring out your pre-frozen Gatorade cubes, ensuring they have been frozen overnight for a solid, icy texture.
Add the frozen Gatorade cubes into your blender, followed by the ice cubes to enhance the slushie texture.
Pulse the blender in short bursts to start breaking down the ice and Gatorade, listening for a crunchy, icy sound and watching the mixture become coarsely blended.
Once the mixture starts to clump and resemble a slushy consistency, add in the optional flavored syrup or fruit juice for an extra burst of flavor.
Blend again with short pulses until the mixture is smooth but still icy, with small frozen chunks visible, about 30 seconds.
Pour the vibrant, icy slushie into glasses, allowing some of the crushed ice to overflow slightly for a playful presentation.
Serve immediately with a straw or spoon, enjoying the bright colors and icy, refreshing texture that’s perfect for a hot day.
