Step 1 In a medium saucepan heated over medium-high heat, combine the cocoa powder, corn syrup, sugar, coffee extract and water and cook, stirring constantly with a whisk to prevent the cocoa from burning, until the fudge sauce bubbles and is thick enough to coat the back of a spoon, about 5 minutes.
Step 2 Remove from heat, add the chocolate and stir until the chocolate is melted, 1 to 2 minutes. Stir in the brandy and set the fudge in a warm place until you are ready to serve it.
