Instructions: Grease an 8-inch-square pan. Combine chocolate chips, brown sugar, peanut butter, corn syrup, and butter in a microwave-safe bowl.

Microwave 2 to 3 minutes, until melted, stirring every 30 seconds.

Stir in nuts and cereal. Press into pan.

Topping: Microwave peanut butter and chocolate chips on medium 2 to 4 minutes, until melted, stirring every 30 seconds. Pour over bars; spread evenly. Refrigerate several hours to set.

These bars disappear very quickly, so you may want to double the 2 cups of marshmallows when you melt the first group of ingredients.

Makes 16 bars.
