Line a 9-inch square pan with parchment paper and set aside. In a small saucepan over medium heat, gently bring the honey to a boil and allow it to boil for one minute. Remove the boiled honey from the heat, then stir in the nut butter until smooth.
Place the cereal in a large bowl, then add the nut butter and honey mixture. Stirring well, until all of the cereal is well coated.
Press the mixture into the prepared pan, pressing hard to pack the bars tightly. Freeze the bars for at least 30 minutes.
After bars have hardened, carefully slice and serve chilled.
