I've made from the box in that Eagle Brand puts out around the holiday and I have some recipes at home. But here are a few that look good.

The following looks the best to me and use the evaporated milk for a richer taste.

Also, if you want to experiment search for fudge recipes on the web. The more cocoa and sweetened milk in them the richer they will taste. Personal I like carmel on them too....I'll have to remember to bring the recipes from home, but I won't be back to work until Tuesday so you might have to be patient.
