Adjust the oven rack to the upper-middle position and preheat the oven to 450°F (230°C). Line a rimmed baking sheet with parchment paper.
In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until evenly combined.
Pour in the heavy cream and stir just until a shaggy dough forms, about 30 seconds. Do not overmix.
Turn the dough out onto a lightly floured surface and gather it into a ball. Knead briefly until smooth, about 30 seconds. If the dough is too crumbly, add 1 teaspoon more heavy cream and knead again; repeat if necessary.
Pat or roll the dough to about 3/4-inch thickness. Dip a 2 1/2-inch round biscuit cutter in flour and cut out biscuits, recombining scraps and repeating until you have 12 biscuits.
Place the biscuit rounds on the prepared baking sheet. (If desired, wrap the sheet with biscuits in plastic wrap and refrigerate for up to 2 hours before baking.)
Bake until the biscuits are golden brown, about 15 minutes, rotating the sheet halfway through baking.
Transfer the biscuits to a wire rack and let cool for 5 minutes before serving.
