1 can (5 ounces) evaporated milk
1 2/3 cups sugar
1/2 teaspoon salt
2 1/2 cups miniature marshmallows, divided
1 1/2 cups (9 ounces) semisweet chocolate chips
1 cup peanuts, divided
1 teaspoon vanilla extract
1. Coat an 8-inch square baking dish with nonstick cooking spray.
2. In a large saucepan, combine the evaporated milk, sugar, and salt over low heat. Bring to a boil and allow to boil for 5 minutes, stirring constantly.
3. Remove the saucepan from the heat and add 2 cups marshmallows, the chocolate chips, 3/4 cup peanuts, and the vanilla, stirring until the marshmallows and chocolate chips are melted.
4. Pour the mixture into the baking dish and top with the remaining 1/2 cup marshmallows and 1/4 cup peanuts, gently pushing them into the fudge. Allow to cool until firm, then cut into 1-inch squares. Serve, or store in an airtight container until ready to serve.
