Preheat oven to 325°F (or to 300°F if using dark nonstick pan). Place paper liners in 36 miniature muffin cups. Crust: Mix walnuts, 4 teaspoons sugar and the Fleischmann's in medium bowl until well blended. Press about 1 teaspoon of the walnut mixture firmly onto bottom of each prepared muffin cup. Bake 5 minutes. Cool. Filling: Place cream cheese, pumpkin, 1/4 cup sugar, the sugar substitute, vanilla, 1/2 teaspoon cinnamon, the cloves and nutmeg in large bowl; beat with electric mixer on medium speed until well blended. Gradually add eggs one at a time, beating on low speed after each addition just until blended. Spoon evenly over crusts. Bake 15 minutes or until centers are almost set. Cool. Refrigerate at least 2 hours or until chilled. Top with the Reddi-wip just before serving. Sprinkle with additional cinnamon, if desired.
