In a large bowl, combine the first six ingredients. Cut in butter until mixture resembles coarse crumbs. Stir in pecans. Combine pumpkin and cream; stir into dry ingredients. Turn onto a floured surface; knead four to six times. Roll to 1/2-in. thickness; cut with a 2-1/2-in. biscuit cutter. Place on a greased baking sheet. Bake at 400° for 12-15 minutes or until golden brown. If desired, serve warm with melted butter and cinnamon sugar.
