These decadent Chocolate Peanut Butter Rice Crispy Bars are not your ordinary Rice Krispie treat! With only 5 ingredients, less than 10 minutes prep and made in the microwave, you'll be making this "gourmet" rice crispy treats recipe from Mothers Day to Christmas parties.
Line a 9x9 square pan with parchment paper. See NOTES for easy how-to. You can also lightly coated the pan with cooking spray or line it with aluminum foil, then coat with cooking spray.
In a large, microwave-safe bowl, add the peanut butter, chocolate chips, butter and marshmallows. No need to stir, yet. Microwave at HIGH (mine is 1100 watts) for 1 minute 30 seconds. (If your microwave wattage is higher, reduce the time by 15 seconds.)
Carefully remove the bowl and place on a trivet or kitchen towel. Slowly stir the mixture until the marshmallows and butter melt and everything is combined.
If your marshmallows are still lumpy or mixture isn’t glossy, you can just microwave it again 15 seconds at a time and stir until smooth and glossy.
Stir in the crispy rice cereal just until well coated. Pour the mixture into the prepared pan. Place in the refrigerator for 1 ½ hours or until firm enough to cut into bars or squares. No need to cover it while it’s chilling.
I like to store these peanut butter chocolate rice crispy bars in the fridge but they can be stored in a cool place on your counter, too.
These peanut butter chocolate rice krispies can be stored or served in a cool place on the counter or in the fridge. They can be made ahead and stored in the fridge for up to one week.
Yield: 16 squares or 32 bars
Notes
How to Line a Pan with Parchment Paper: To easily line a pan with parchment paper, first fit the paper into the pan and mark the corners by pinching them with your fingers. With scissors, cut from the corner tips to the pinched spot on all four corners. This will allow the paper to easily fit into the pan.Substitutions:-Regular size marshmallow can be used but mini marshmallow melt faster in the microwave.-A 7 ounce container (1 ½ cups) of marshmallow cream will also work. I tested it just to make sure 7 ounces was enough.-If you have chocolate flavored rice crispy cereal, that will also work!
