Preheat oven to 425 degrees.
Combine first 5 ingredients in medium bowl. Cut in butter until mixture is crumbly. Using fork, stir in enough cream to form a soft dough.
Gently knead on lightly floured surface until smooth, butter may still be in lumps, about 10 times. Pat dough out to thickness of 3/4-inch. Cut out 2-inch biscuits using floured cutter.
Transfer to ungreased baking sheet. Gather scraps, knead briefly and cut additional biscuits. Bake until golden brown, 15 to 18 minutes.
