Can I smooth out whip cream frosting the same way I do with butter cream? I mean as far as the paper towel method? Or the upside down method? Or if any one else has a method please let me know.
No. The only way to smooth whipped cream is to very carefully go over it with a spatula or bench/bowl scraper.
Yes, only a spatula. The reason is because whipped cream doesn't crust over.
