Adjust oven rack to upper-middle position and heat oven to 450°F Line baking sheet with parchment paper.
Whisk together flour, sugar, baking powder, and salt in medium bowl. Stir in the cream with a wooden spoon until dough forms, about 30 seconds, Turn the dough out onto a lightly floured counter and gather into a ball. Knead the dough briefly until smooth, about 30 seconds.
Shape the dough into a 3/4 inch thick circle. Cut biscuits into rounds or wedges. Place rounds or wedges or parchment-lined baking sheet. (the baking sheet can be wrapped in plastic wrap and refrigerated for up to 2 hours). Bake until golden brown, about 15 minutes, rotating baking sheet halfway through baking.
FYI Unlike traditonal biscuits, cream biscuits benefit from relatively rough treatment. A biscuit that was kneaded for 30 seconds before baking rose higher than a biscuit that was gently handled.
