Add pumpkin and eggs; beat until combined, scraping sides of bowl as needed. Add bourbon and the next 5 ingredients (through ground allspice); beat 1 minute or until combined. Pour cheese mixture into prepared pan. Place pan in a large roasting pan; add hot water to pan to a depth of 1 inch. Bake at 350° for 35 minutes or until center barely moves when side of pan is tapped. Cool completely on wire rack. Cover and refrigerate at least 4 hours or overnight. Place cream and powdered sugar in a small bowl; beat with a mixer at high speed until stiff peaks form. Serve sweetened whipped cream with tart.
