Cook the pasta according to package directions.
In a saucepan or skillet over low heat, warm the butter and cream. Season with salt and pepper.
Place half of the Parmesan into a large serving bowl. Pour the warm butter/cream mixture over the top.
Drain the pasta and immediately pour it into the bowl. Toss a couple of times, and then sprinkle in the other half of the Parmesan. Toss to combine, thinning with pasta water if necessary.
Serve immediately as a main course or accompaniment to meat or salad.
