This is not a baking exercise, but I used this for my ice cream cake a couple of weeks ago, and it was a hit with my co-workers. I also saved some for my ice cream topping. The kahlua was not cooked off, so this is not advised for minors that are not supposed to consume alcohol.
1 ½ cups dark chocolate
¼ cup milk
½ cup whipping cream
3 tbsps. of Kahlua
1 tbsp. Instant coffee
1/4 cup hot water
Dissolve the instant coffee in the hot water and set aside.
Place chocolate in a mixing bowl, making sure that they are broken into small pieces for easy melting.
In a saucepan, combine milk and cream over medium-high heat. Bring to boil and then remove from heat. Pour hot milk and cream over chocolate. Stir until smooth. Add the coffee mixture, then add the Kahlua and continue whisking until combined.
This should make about 1 ½ cups.
