Love Heavenly Hash? Then this one's for you. Rich, dark chocolate enrobes marshmallows and walnuts in this easy-to-make candy. And if you like this, check out a couple of other candies: Pecan & Salted Caramel Candies and Dark Chocolate Buttercrunch.
Line an 8" x 8" square or 9" round pan with parchment, and grease the parchment. If you don't have parchment, use waxed paper or plastic wrap.
Combine the chocolate, cream, espresso powder, corn syrup, and vanilla in a microwave-safe bowl.
Heat the mixture in the microwave (or in a saucepan set over low heat on the stove) until the cream is hot and the chocolate has softened.
Remove from the heat, and stir until the chocolate has melted and everything is smooth.
Spread about 3/4 cup of the melted chocolate in the bottom of the pan.
Space the marshmallow halves atop the chocolate. Note: feel free to substitute mini marshmallows for the marshmallow halves here. Distribute the walnuts evenly in the spaces between the marshmallows.
Spread the remaining chocolate atop the marshmallows and walnuts, spreading to the edge of the pan so that everything is covered.
Refrigerate for an hour or so, to set the chocolate. Remove from the refrigerator, and loosen the candy from the edges of the pan.
Bring to room temperature, and leave in the pan, covered with plastic, until you're ready to cut into squares.
