A love of cheesecake is easily soured when you look at what goes into it.

Many versions have 30 or even 40 grams of fat per slice and can call for a pound of full-fat cream cheese in addition to sour cream, half a dozen egg yolks and half a stick of butter, or more, in the crust.Fortunately, it is possible to make a healthier yet still satisfying cheesecake. It's just a matter of choosing the right ingredients.This cafe mocha cheesecake is rich and velvety, yet has just two-thirds of the fat and half the calories of traditionally-made versions.To lighten up the filling, full-fat cream cheese is swapped out for a mixture of pressed and pureed nonfat cottage cheese and reduced-fat Neufchatel cream cheese. An additional hit of creaminess comes from reduced-fat sour cream.For a rich, chocolaty flavor, cocoa powder is used instead of semi-sweet chocolate. Cocoa powder contains only a small fraction of the fat of chocolate. Instant espresso powder and coffee liqueur, such as Kahlua, are added to enhance the flavor of the chocolate.Finally, a light crust is made (without all the butter) by simply coating the bottom and sides of the pan with crushed chocolate wafer cookies. If you like, you could use plain or chocolate graham crackers instead.Cafe MochaCheesecakeStart to finish: 1 hour 25 minutes (25 minutes active), plus 5 hours cooling timeServings: 166 chocolate wafer cookies or chocolate graham crackers1 tablespoon plus 1 cups sugar2 tablespoons instant espresso or dark roast coffee powder2 1/2 tablespoons coffee liqueur, or water2 cups nonfat cottage cheese1 cups reduced-fat sour cream12 ounces Neufchatel (reduced-fat cream cheese)6 tablespoons all-purpose flour2 large eggs2 large egg whites2 tablespoons unsweetened cocoa powderteaspoon ground cinnamonteaspoon saltCocoa powderHeat the oven to 300 F.
