Add the ice, milk, ice cream, vanilla and sugar to a food processor or blender, and pulse until smooth.
Serve garnished with whipped cream if desired.
Notes
Depending on how thick you prefer your drink to be, you can easily customize it by adding more or less ice. Want a thicker frappuccino? Add extra ice cubes. Prefer a lighter texture? Reduce the amount of ice.Instead of continuously blending, pulse the blender in short bursts. This technique gives you better control over the texture and helps prevent over-blending, resulting in a smoother and creamier frappuccino.
