Imagine the perfect holiday drink that combines coffee and chocolate and throws in a bit of peppermint! Well, this super smooth drink/dessert has all those things!
In a large measuring glass, mix together the sugar, cocoa, cornstarch, salt and water.
Cook in the microwave for 2 minutes. Stir and cook another 2 minutes. Stir once again. If the mixture is thick and viscous, the sauce is ready. If it is runny, cook an additional minute.
Add the butter and vanilla and stir until smooth. Set aside.
For the coffee cooler
In a large bowl, combine the instant coffee and milk. Stir to dissolve the coffee granules.
Stir in the chocolate sauce and sugar until the sugar is dissolved.
Add the liquor, if using.
To serve, place several small scoops of peppermint ice cream in glasses (like flutes) and top with coffee cooler.
