This is a no-fuss dessert at it's best. It's like a Nestle Crunch or Hershey Krackel bar plus rocky road fudge: chocolate, peanut butter, crispy rice, and fluffy marshmallows all in one delicious, SIMPLE homemade candy bar. It's perfect for holiday candy and cookie trays! BONUS: it's naturally gluten free! Adapted gently from "The Simple Kitchen" by Chad and Donna Elick.
Line a 9-inch by 13-inch baking pan with aluminum foil, shiny side down. Spritz with non-stick cooking spray. Set aside.
Add the chopped chocolate to a large, microwave safe bowl. Melt in the microwave at 50% power in 30 second bursts, stirring after each burst, until the chocolate is completely smooth. Stir the peanut butter into the warm chocolate until fully incorporated. Add the rice cereal, marshmallows, and salt and stir until everything is evenly coated.
Scrape the mixture into the prepared pan and smooth gently with a spatula. Let rest at cool room temperature until firm or stash in the refrigerator or freezer to speed the process. Once the candy bars are solid, cut into 24 to 48 pieces, depending on how generous you want to be.
