Ingredients

1 cup sugar 

1/2 cup heavy cream 

4 tablespoons (1/2 stick) unsalted butter, cut into small pieces 

Kosher salt 

1 tablespoon whiskey 

2 pints coffee ice cream 

Fudgy Double-Chocolate Brownies

Whipped cream for serving 

Preparation

Combine sugar with ¼ cup water in a medium saucepan. Bring to a boil over medium-high, cook until amber and just beginning to smoke, about 4 minutes. Remove from heat, carefully whisk in heavy cream, butter, and 1 teaspoon kosher salt. Stir in whiskey. Use immediately for sundaes. (Sauce can also be cooled and stored in an airtight container in the refrigerator for up to 1 month. Gently reheat before serving.)

Layer scoops of ice cream and crumbled brownies in each sundae glass. Top with Whiskey Caramel Sauce and softly whipped cream. Serve immediately.
