Immersion blenders can be used in many different ways. If you have an immersion blender equipped with a whipping disc (basically flat, but ever so slightly domed disc with no holes), capable of at least 6,000 rpm, then possibly you can make a quick and easy “whip” to satisfy sweet tooth desires. A whip is thicker than a shake would be, since a spoon can stand up in a whip and a whip has the consistency of thick whipped cream. Some devices have two speeds–6,000 rpm and 12,000 rpm. 6,000 rpm is adequate for whipping ice cold fat-free milk.
