Ingredients

1 envelope (1/4 ounce) unflavored gelatin 

1 cup heavy cream 

1/2 cup sugar 

4 ounces semisweet chocolate, finely chopped 

2 tablespoons instant espresso powder 

1/4 teaspoon salt 

2 cups milk 

Whipped cream, for serving (optional) 

Preparation

In a medium saucepan, sprinkle gelatin over 1/4 cup cold water, let soften 5 minutes. Add heavy cream and place over low heat. Add sugar, chocolate, espresso powder, and salt. Whisk until chocolate has melted, espresso powder is dissolved, and mixture is well combined, about 2 minutes.

Whisk in milk and strain mixture into a large measuring cup (for easy pouring). Divide evenly among six 6-ounce coffee cups or custard cups. Refrigerate until set, at least 3 hours. Serve with a dollop of whipped cream, if desired.
