Preheat oven to 400 degrees F.

In a large bowl, mix together flour, sugar, baking powder, and salt.

Pour in heavy cream and add raspberries, blackberries, or chocolate chips if using.

Gently mix until the dough just comes together, being careful not to overmix.

Turn the dough out onto a lightly floured board.

Pat the dough into a 10 x 1 1/2 inch round.

Cut the round into 8 triangles.

Brush the tops of the triangles with melted unsalted butter.

Sprinkle the buttered tops with sugar.

Place the scones 1 inch apart on a parchment-lined baking sheet.

Bake for approximately 12 minutes, or until lightly browned on top.

Cool slightly before serving.
