We are fortunate enough that Witt has not had any reaction to food that carries the warning of "Created on a line that process dairy, etc." That means we can use Ghirardelli Semi-sweet chocolate chips! Yummm....
To create chocolate squares, I melt the chips with a little bit of coconut oil (you could also use DF margarine). Then I pour the melted chocolate onto a wax paper lined tray. Smooth it out to the thickness I want and refrigerate.
Since coconut oil is solid above 77, it doesn't take long to harden. Then you can take it out and cut it into squares with a knife.
Then if you want, add some roasted marshmallows and a couple of graham crackers! :)
