To make biscuits: In a large bowl, combine flour, baking powder and salt. Add butter cubes, and using your fingers, a fork or a pastry blender, mix until coarse little crumbles remain. Make a well in the middle of the flour, then add cream and cheese. Stir until a sticky dough forms, then make 8 small rounds of dough.
