One of my favorite lab accessories is a big square of wax paper. Some labs keep t his stuff around for weighing. If not, you can get some at the grocery store, or use aluminum foil.
Get a big, smooth square of foil or wax paper. Place it over the funnel, and dump the whole thing over on it. Fish out the paper with forceps.
Often I go for the "scrape it up with a spatula" method too, usually when I have smaller amounts of product.
Bonus: on dry days, the aluminum foil acts as a great static electricity dissipator so that you don't get fluffy product flying everywhere.
