Preparation

Step 1

1. Coat a 9-inch square baking pan with cooking spray; line with parchment. Sprinkle gelatin over 1/3 cup water in the bowl of a mixer; let stand for 5 minutes.
2. Heat granulated sugar, corn syrup, remaining 1/3 cup water, and 1/8 teaspoon salt in a saucepan over medium-high heat, stirring occasionally, until syrup reaches 238 degrees on a candy thermometer, about 5 minutes.
3. Whisk gelatin in mixer on low speed, adding syrup in a slow, steady stream down side of bowl. Whisk, gradually increasing speed to high, until almost tripled in volume, about 8 minutes. Whisk in vanilla. Transfer to baking pan. Smooth top. Let stand until set, at least 3 hours.
4. Cut out nine 2 1/2-inch square marshmallows using a cookie cutter or a knife dipped in confectioners' sugar. Dip surface of crackers into chocolate to coat, and transfer to parchment-lined baking sheets. Refrigerate until set, about 10 minutes. Sandwich marshmallows between crackers, chocolate sides in.
5. Dip half of each sandwich into chocolate, on the diagonal; sprinkle with peanuts, and transfer to a parchment-lined baking sheet. Refrigerate until set, about 10 minutes.
