1/2 cup sugar
1/3 cup cocoa
2 1/2 cups strong brewed coffee
1/4 cup coffee liqueur
1 teaspoon vanilla extract
2 cups milk
Stir together first 5 ingredients in a saucepan; cook, whisking
constantly, over medium heat, 5 minutes or until thoroughly heated.
Microwave milk in a 2-cup glass measuring cup at HIGH 2 minutes, or
until thoroughly heated. Pour one-third hot milk in a heat-proof jar;
seal with lid. Shake until frothy. Repeat twice with remaining milk.
Pour coffee into 4 mugs; top with frothed milk. Serve immediately.
