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.
