Coffee-Creme Caramel

I have so much eggs and half gallon of milk in my fridge plus the two guys I live with are craving forCreme Caramel or more known in my country (Philippines)as Leche Flan. The thing that caught me is realizing that I don't have vanilla essence on hand so I simply grabbed my instant coffee powder and diluted it in hot water and added in into the custard mixture. Came out good! Best eaten when chilled.
