Rocky Road Fudge


16 ounces semisweet chocolate, chopped finely (or use good quality chocolate chips)
2 ounces unsweetened chocolate, chopped finely
1/2 teaspoon baking soda
1/8 teaspoon salt
1 (14-ounce) can sweetened condensed milk
1 tablespoon vanilla extract
1 cup mini marshmallows
1 cup roughly chopped peanuts
1/2 cup semisweet chocolate chips


1. Line 8x8-inch baking pan with foil and spray lightly with nonstick spray.

2. In a medium, heatproof bowl, toss 1st two chocolates with baking soda and salt. Stir in sweetened condensed milk and vanilla. Set bowl over 4-quart saucepan containing 2 cups simmering water. Stir with rubber spatula until chocolate is almost fully melted and few small pieces remain, 2 to 4 minutes.

3. Remove bowl from heat and continue to stir until chocolate is fully melted and mixture is smooth. Stir in marshmallows, peanuts and additional chips. Scrape fudge into prepared pan and spread in an even layer with rubber spatula. Refrigerate until set, about 2 hours (or longer). Remove fudge from pan using foil. Peel off foil and cut into squares.

    Why baking soda?

      @Gina-Nicole, You know, there was a reason for adding the baking soda in the original CL recipe but I’m not recalling what it is!

      What CI says about the baking soda: Seeking a firmer, lighter texture for our fudge recipe, we found that a little baking soda reacted with the acids in the chocolate to alter the pH, which made the fudge drier and firmer.

    I can vouch that this recipe is delicious!!!!! [I don’t see any differences or adaptations to the Cook’s Illustrated original recipe, which I made.] And it’s simple and easy to make. Highly recommended!

      I must have changed something slightly in the directions or something… which is why it says “slightly!” Can’t remember. Glad you enjoyed!

    I made this recipe for my sister to take to work. It turned out fabulous! The key is the baking soda. Makes it silky smooth and tender. I used half dark chocolate and half semi-sweet. This is definitely a keeper
