Adjust oven rack to upper-middle position and heat oven to 450 degrees.
Line baking sheet with parchment paper and set aside.
In medium sized bowl, whisk together flour, sugar, baking powder and baking soda.
Microwave cream for about 60-90 seconds until just warmed to body temperature (95 to 100 degrees ).
Stir cream into flour mixture until a soft, slightly sticky dough forms.
Oil lightly a 1/4 cup measuring cup ( use 1/3 cup for larger or sandwich biscuits).
Scoop out dough until cup is nearly full.Drop scoops of batter 2 inches apart on prepared sheet. Reoil measuring cup after every 3 or 4 scoops. If portions are misshapen, use your fingertips to gently reshape dough.
Bake for 10-12 minutes until tops are a light golden brown, and they feel firm to the touch.
Once baked, remove from heat and brush biscuits with melted butter if you desire.
Serve warm or refrigerate for use within 1-2 days.
