Begin by ensuring your Coca-Cola is well chilled—this helps achieve a thicker, more slushy texture.
Pour the chilled Coca-Cola into a blender, filling it about halfway to allow space for ice.
Add crushed ice to the blender with the Coke, using roughly one cup for a nicely textured slushie.
Secure the lid on the blender and blend on medium-high speed for about 20-30 seconds, until the mixture looks frothy and smooth with a velvety consistency.
Stop blending and check the texture—if still too icy or grainy, blend for a few more seconds until it turns silky and uniform.
Scoop the bright, bubbly slushie into glasses or cups, letting the mixture pile up slightly for a satisfying presentation.
Serve immediately with a straw or spoon, enjoying the refreshing, velvety coolness of your homemade Coke slushie.
