½–1 tsp instant espresso powder or instant coffee*
Instructions
In a saucepan over medium heat, whisk together water and cornstarch.
Stir in molasses, brown sugar and butter.
Bring to a gentle simmer and stir until butter melts, sugar dissolves and sauce is smooth and begins to thicken (less than 5 minutes).
Remove from heat and stir in vanilla and coffee.
Notes
*If you don’t have instant coffee or espresso, simply substitute ½ cup brewed coffee for the water in step 1. The end result will be a sauce with a stronger coffee flavour.
