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.
