Preheat the oven to 400 degrees. Line a sheet pan with parchment paper.
Sift the flour, sugar, baking powder, and salt into the bowl of an electric mixer fitted with the paddle attachment.
Add the butter and mix on low speed until the butter is the size of peas. In a measuring cup, combine the eggs and heavy cream and, with the mixer still on low, add to the flour mixture. Mix until just combined. The dough will be sticky.
Dump the dough out onto a well-floured surface. Flour a rolling pin and roll the dough 1/2 to 5/8 inch thick. You should see lumps of butter in the dough.
Dip a 2-inch round cutter in flour and cut 16 to 18 biscuits. Place on the sheet pan, brush the tops of the biscuits with the egg wash, and sprinkle with sugar.
Bake for 15 to 20 minutes, or until the tops are golden brown and the insides are fully baked. Remove from the oven and allow to cool on the pan.
