Begin by placing the two cans of White Claw hard seltzer in the freezer for 2-3 hours until they are partially frozen. This step ensures a slushie-like consistency.
Once the White Claw cans are sufficiently chilled, remove them from the freezer and set aside.
In a blender, combine the ice cubes, frozen fruit, and sweetener (if desired). Blend until the mixture becomes smooth and slushie-like in texture.
Open the partially frozen White Claw cans and pour them into the blender with the fruit and ice mixture.
Blend again until all the ingredients are thoroughly combined, resulting in a refreshing White Claw slushie.
Taste the slushie and adjust the sweetness if necessary by adding more sweetener or fruit.
Pour the slushie into glasses or mason jars, and if desired, garnish with fresh fruit or herbs.
Insert drinking straws or spoons, and serve immediately to enjoy the invigorating flavors of the White Claw slushie.
