Measure out a cup of ice cubes and place them into your blender.
Pour in a cup of cold milk and half a cup of heavy cream, ensuring both are chilled for the best icy texture.
Add two tablespoons of sugar to sweeten the mixture, then pour in a teaspoon of vanilla extract for that rich vanilla aroma.
Sprinkle a tiny pinch of salt to enhance the vanilla flavor.
Secure the lid and blend on high for about 30 seconds, until the mixture is thick, frosty, and slushy, with a smooth texture that coats the sides of the blender.
Check the consistency—if it’s too runny, add a few more ice cubes and pulse again until it reaches your desired thick, icy texture.
Pour the slushie into glasses immediately, enjoying the thick, creamy, and cold treat with a vanilla fragrance.
If not consuming right away, place the glasses in the freezer for 10 minutes to firm up further without melting too much.
Give the slushie a quick swirl or pulse before serving for an extra smooth sip.
Enjoy your homemade vanilla slushie immediately for the best frosty, creamy experience.
