Fudge not setting up-- any salvaging possible? Alternate uses?

I made fudge with evaporated milk I made myself. Added this to butter and sugar and heated. Added this to chocolate and stirred enough to mix. Poured into 8x8 dished and left to set up. No such luck. What I have is silky thick hot fudge sauce-like chocolate. Kind of like soft caramel. What can I use this for now or do y'all have suggestions as to how to fix it?
