The mudslide is like drinking dessert -- something that seems oh-so-right when it's hot outside. It's admittedly hard to pass up on this sweet drink, with its combination of chocolate and coffee flavors, splashed with cream, a kick of vodka and poured over ice. Unless you're watching your waistline, that is. A mudslide, with its mix of Kahlua, Irish cream liqueur, cream and vodka packs nearly 500 calories into a single 8-ounce serving. Some mix-masters take it up a notch by adding a scoop of vanilla ice cream. Now that's a serious diet disaster.
