Add cream, butter, espresso powder, vanilla and salt to a saucepan. Bring to a boil and stir until you have a uniform consistency.
½ cup heavy cream, 3 tablespoons unsalted butter, ½ teaspoon instant espresso powder, ½ teaspoon vanilla extract, pinch of table salt
Take off the heat and add the Bourbon.
2 tablespoons Bourbon
Pour the hot cream mix over the chocolate and let sit for 1 minute.
Stir together until everything is well combined and no chocolate clumps remain. (If you end up with a few small pieces of unmelted chocolate, set the mixing bowl over a small pot filled with hot water to melt the remaining chocolate.)
Recipe notes:
Use the glaze on chocolate Bundt cake and serve with raspberry jam and/or whipped cream.
