Mix butter, sugar, cream, and molasses in mixing bowl. Stir in remaining ingredients; cover. Refrigerate at least 3 hours.
Heat oven to 375 degrees. Divide dough into 4 parts. Roll each part ⅛-inch thick on lightly floured cloth-covered board. Cut into 2-1/2 inch circles with a scalloped cookie cutter. Place 1-inch apart on greased baking sheets or lined with parchment.
Bake until light brown, about 8 minutes. Cool on wire rack. Makes about 3-1/2 dozen.
