12 ounces chocolate chips, semisweet, bittersweet or milk chocolate
1/2 cup creamy or crunchy peanut butter
3 cups crisp rice cereal (like Rice Krispies)
2 cups mini marshmallows
1/2 cup chocolate chips or peanut butter chips (Reese's!)
1. Lightly grease an 8X8- or 9X9-inch baking pan and set aside.
2. Melt chocolate in a sauce pot being careful not to burn. Stir in the peanut butter until combined. Let the mixture cool slightly, about five minutes.
3. Add the rice cereal, marshmallows and chocolate chips and/or peanut butter chips. Fold together with a rubber spatula until well combined. Pour the mixture into the prepared pan. Press additional marshmallows and peanut butter chips into the top of the bars, if desired.
4. Let the bars cool and set for 5-6 hours until they are firm and no longer gooey. Once the bars are firm and set, cut into squares and serve.
