Prep Time 2 minutes
Setting Time 3 hours
Cook Time 3 minutes
Total Time 3 hours 5 minutes
Servings 8 bars


  • 3 tablespoons honey (or agave for vegan)
  • cup peanut butter (smooth or crunchy)
  • 3 cups Original Cheerios
  • ½ cup shelled peanuts
  • 1 handful of sea salt (optional)


  • Line an 8-inch square cake pan with parchment paper and set aside.
  • Add the honey and peanut butter to a large pot over low heat and stir until combined.
  • Use a spatula to fold in the Cheerios and peanuts, being careful not to crush the Cheerios, until the Cheerios and peanuts are completely coated.
  • Transfer to lined cake pan and use your spatula to lightly press the mixture down flat.
  • Refrigerate until completely solid—about 3 hours. Cut into bars in the size of your choice. Sprinkle on some sea salt for a salty-sweet finish (optional).
  • Individually wrap and store in the refrigerator.

Pro Tips

  • Depending on the salt content of the peanut butter and the peanuts you are using, you may or may not want to add the extra salt—taste them first!
  • This recipe is designed for the use of Original Cheerios. Using Cheerios with flavoring such as Honey Nut Cheerios, Strawberry Cheerios, etc, will probably make your cereal bars too sweet.
