Try Carbona Stain Devils. They have one specifically for coffee, tea & cola that also works for chocolate. If you only washed it & not put it in the dryer, it will be easier to get out. If you put it in the dryer already, you may have to treat it a few times before it will all come out. Be patient, but it will come out.

Try soaking the cotton clothing in some oxygen cleaner. I purchase the off brand at Family Dollar or Dollar General Stores.
You might have to soak them for several days before you launder.
