Preheat the oven to 425°F (220°C).

In a large mixing bowl, combine the self-rising flour and sugar. Mix them together until evenly combined.

Gradually add the heavy cream into the dry ingredients. Stir gently until a dough forms. The dough should be slightly sticky but not too wet.

Flour a clean surface and turn the dough out onto it. Gently pat it into a rectangle or circle, about 1 inch thick.

Shape the biscuits using a biscuit cutter, a drinking glass, or a knife. If using a knife, cut the dough into squares or rectangles.

Place the biscuits on a baking sheet lined with parchment paper for easy cleanup.

Bake the biscuits in the preheated oven for about 12-15 minutes, or until they are golden brown on top.

Remove the biscuits from the oven and let them cool for a few minutes before serving.
