  • Peanut Butter. Will help glue all of the ingredients together and give flavor to the bars. I used smooth peanut butter, but feel free to use crunchy peanut butter if you like

How to make this Cereal Bar recipe

Line bottom of a 9-inch square baking pan with parchment paper, and spray the sides with cooking spray. (You can also use an 8-inch pan instead)

Mix the cereal and peanut butter chips in a large bowl and set aside.

Over a medium sized sauce pan, mix the peanut butter, light corn syrup and salt. Heat on medium heat until mixture just starts to simmer, around 3 minutes, stirring constantly. Remove from heat and stir until smooth and lightly cooled, but still creamy enough to mix with the cereal.

Pour the peanut butter mixture on top of the cereal mixture and stir until everything is well coated. Using a small piece of baking sheet, press mixture in an even layer on your prepared square pan as tightly as possible. You can also use the back of a spoon to do it.

Refrigerate for 1 hour until set. Remove from the pan and cut in 9 equally sized squares and enjoy!
