Recipe Tips

  • Peanut butter and honey can be melted in the microwave. Add to a microwave-safe bowl and heat in 30-second increments until melted enough to stir together.
  • Choose your favorite O-shaped cereal! There are many varieties out there. Cheerios, Nature’s Path, and One Degree Organics. I used regular Cheerios for this recipe.
  • This wil also work with rice Krispies, puffed wheat, shreddies, Chex, or any other cereal with small shapes.
  • Any style of nut butter or seed butter will work for this recipe. Peanut butter is usually a popular option. Almond butter, sunflower seed butter, or even tahini!
  • Honey adds sweetness and glues things together. You can swap it for corn syrup, maple syrup, or rice malt syrup.
  • I’ve also made this recipe into ball shapes. Just grab a spoonful of the mixture and form it into a ball with your hands.

How to Store Leftovers

  • Refrigerate – Leftover bars can be stored in a zip-top bag or air-tight container in the fridge for up to 5 days
  • Freeze – Leftover bars can be stored in the freezer for up to 2 months. If freezing, place them in a single layer on a baking sheet and freeze for 2 hours. Then add them to an airtight container or zip-top freezer bag.
