Spiced Pumpkin Tiramisu

Directions

1. In a small saucepan, combine water, coffee, sugar and liqueur; cook and stir over medium-low heat until sugar is dissolved, about 3 minutes. Transfer to a shallow bowl; cool completely.
2. In a large bowl, mix mascarpone cheese, pumpkin, 3 tablespoons sugar and spices just until blended. In a small bowl, beat cream until it begins to thicken. Add remaining sugar; beat until soft peaks form. Fold into mascarpone mixture.
3. Quickly dip 18 ladyfingers into coffee mixture, allowing excess to drip off. Arrange in a single layer in a 13x9-in. dish. Spread with 1-2/3 cups cheese mixture. Repeat layers twice.
4. Mix sugar and cinnamon; sprinkle over top. Refrigerate, covered, at least 8 hours or overnight.
