2/3 cup reduced-calorie chocolate wafer crumbs (about 20 cookies)
2 tablespoons sugar
1 tablespoon stick margarine, melted
1 tablespoon water
Cooking spray
3 ounces semisweet chocolate, chopped
2 tablespoons skim milk
1 1/4 cups sugar
3 (8-ounce) blocks fat-free cream cheese
1 (8-ounce) block 1/3-less-fat cream cheese
1 tablespoon vanilla extract
1/4 teaspoon salt
4 large egg whites
1/2 cup Dutch process or unsweetened cocoa
1/2 cup hot fudge topping
1 cup low-fat sour cream

Preheat oven to 400 degrees F.

Combine first 4 ingredients in a bowl, and toss with a fork until blended. Press crumb mixture into the bottom of a 9-inch springform pan coated with cooking spray. Bake at
400 degrees F for 8 minutes. Cool crust on a wire rack. Increase oven temperature to 525 degrees F.


Combine semisweet chocolate and milk in a bowl; microwave at high 45 seconds or until chocolate melts, stirring after 30 seconds. Cool.

Combine 1 1/4 cups sugar, cheeses, vanilla, and salt in a food processor, and process just until smooth. Add egg whites, and process until blended. Add chocolate mixture, cocoa, fudge topping, and sour cream, and process until blended.


Spoon batter into prepared pan. Bake at 525 degrees F for 7 minutes. Reduce oven temperature to 250 degrees F, and bake
25 minutes or until almost set. Cheesecake is done when the center barely moves when the pan is touched. Remove cheesecake from oven; run a knife around outside edge, and cool to room temperature. Cover and chill at least 8 hours.
