Preheat oven to 425 degrees and line a baking sheet with a Silpat liner or parchment paper.

In a large mixing bowl add flour, baking powder, and sugar. Whisk to combine.

Add cold butter to the flour mixture and using a pastry blender mix into the flour until the flour is crumbly with little pieces of butter still present in the dough.

Stir in Parmesan cheese, prosciutto, and chives.

Add in 3/4 cup heavy cream and stir to combine.

If the mixture doesn't fully come together add in a bit more cream until the dough fully comes together and is a bit sticky.

Flour a large cutting board or your counter and turn out the dough.

Flour your hands and form the dough into a 6-inch disk and about 3/4 inch thick.

Cut into 8 pieces and place onto the prepared baking sheet.

Brush the tops of the scones with additional heavy cream.

Place into the oven and cook for 20-25 minutes or until golden brown.

After 15 minutes remove from the oven, top with a small handful of shredded Parmesan cheese, and add back to the oven.

Continue baking until completely baked.

Serve warm with lots of delicious butter.
