Ingredients

1 can (14 ounces) sweetened condensed milk 

2 teaspoons pure vanilla extract 

2 tablespoons bourbon (optional) 

2 cups cold heavy cream 

Preparation

In a medium bowl, stir together condensed milk, vanilla, and bourbon, if desired. In a large bowl, using an electric mixer, beat cream on high until stiff peaks form, 3 minutes.

With a rubber spatula, gently fold whipped cream into condensed milk mixture. Pour into a 4 1/2-by-8 1/2-inch loaf pan. Freeze until firm, 6 hours.
