In a large bowl using electric beaters cream together the soft butter, peanut butter, and salt.
Working in batches alternately add the sugar, and then the cream or half and half, beating between each addition. You may or may not need all the cream. I always do. You want a creamy smooth fairly loose frosting for piping or spreading.
Taste the frosting to add salt, if needed.
Notes
I don't sift my powdered sugar unless it is very lumpy.
