Recipe Ingredients

CEREAL: Choose your favorite O-shaped cereal! There are many varieties out there. Cheerios have a few different flavor options, Nature’s Path has “whole O’s” and One Degree Organics has “honey oat O’s”. I used regular Cheerios.

PEANUT BUTTER: 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 will also work!

HONEY: Used to add sweetness and act as a glue to hold things together. Other ingredients you could substitute include corn syrup, maple syrup and rice malt syrup.

How To Make Cheerios Bars

The best cereal bars are a little thicker and tightly packed together. This version is quick to make and needs a little time to chill before serving.

  1. Melt peanut butter and honey in a pot on the stove.
  2. Add cereal to a bowl, and top with melted peanut butter according to the full recipe instructions below.
  3. Pack tightly into a square on a baking sheet.
  4. Chill for 1-2 hours before slicing and serving.

Variations

I’ve made these as bars and balls. My daughter tends to prefer the ball shape. To make, just grab a spoonful of the mixture and form it into a ball with your hands.

Feel free to replace O-shaped cereal with any other favorites! Rice Krispies, puffed wheat, shreddies, Chex, and any other cereal with smaller shapes will also work for this recipe.

Recipe Tips

  • Peanut butter and honey can be melted together in a pot on the stove or in the microwave. Just add to a bowl and microwave in 30-second increments until melted enough to stir together.
  • It will only take 2-3 minutes for the peanut butter and honey to melt on the stove. Once it’s melted enough to mix together, remove from the heat. It’s easy to burn the sugar from honey, so keep an eye on it and stir frequently.
  • Leftover bars can be stored in the fridge up to 5 days or the freezer 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 bag to be fully frozen for up to 2 months.
  • Cereal bars are an easy addition to any bento box style lunches!
