Spray a 9x9 metal pan with cooking spray.

In a large pot, heat the peanut butter and honey over medium heat for 2 - 3 minutes until completely melted.

Remove pot from heat and stir in the Rice Krispies until well coated.

Using a rubber spatula, spread the Krispie mixture evenly into the prepared pan.

Pop the pan into the refrigerator for about 20 minutes.

Slice into 12 squares and serve.

Squares will keep in an air-tight container for several days.
