Ingredients

2 cup heavy cream

3 tbsp cocoa powder, unsweetened Dutch-process

5 oz semisweet chocolate, chopped

1 cup whole milk

¾ cup sugar

salt

5 egg yolks

½ tsp vanilla extract

1 cup marshmallows, miniature

1 cup walnuts

½ cup chocolate chips

Preparation

Warm 1 C. of the cream with the cocoa powder in a medium saucepan, whisking to thoroughly blend the cocoa. Bring to a boil, then reduce the heat and simmer at a very low boil for 30 seconds, whisking constantly.

Remove from the heat and add the chopped chocolate, stirring until smooth. Then stir in the remaining 1 C. cream. Pour the mixture into a large bowl, scraping the saucepan as thoroughly as possible, and set a mesh strainer on top of the bowl.

Warm the milk, sugar, and salt in the same saucepan. In a separate medium bowl, whisk together the egg yolks. Slowly pour the warm milk into the egg yolks, whisking constantly, then scrape the warmed egg yolks back into the saucepan.

Stir the mixture constantly over medium heat with a heatproof spatula, scraping the bottom as you stir, until the mixture thickens and coats the spatula (and reaches 170 degrees F on an instant-read thermometer).

Pour the custard through the strainer and stir it into the chocolate mixture until smooth, then stir in the vanilla. Mix in your marshmallow, walnuts and chocolate chips. Stir until cool over an ice bath. Freeze for 8 hours before serving cold.
