As much as I love baking, sometimes I just don’t have time. This is why I love these no bake peanut butter cheerio bars. With four simple ingredients, these can be mixed up in 10 minutes or less. I like to make these because I often have all ingredients in my pantry and because they are always devoured in no time!

About these no bake cheerio bars
These cheerio bars have a peanut buttery coating surrounding lots of cheerios. They hold their shape nicely and have the perfect amount of stickiness. They are not-too-sweet and the balance of peanut butter is spot on with the other ingredients. It really is hard to eat just one!

The four ingredients in this recipe are as follows:
Corn syrup - The corn syrup is essentially the binder that keeps it all together while adding some sweetness. Some recipes use honey, but I like the neutral flavor of corn syrup. They have a similar sugar and calorie content, so using honey is not any healthier.
Sugar - The sugar in this recipe is primarily used for sweetness. Over the years, I have reduced the sugar content by half of our original recipe to what it is now, and you can’t even tell a difference.
Peanut butter - The peanut butter also forms the binder and is the predominant flavor. You may use creamy or crunchy peanut butter in this recipe. I do not recommend using no-stir or natural peanut butter.
Cheerios - The Cheerios give the bars substance and crunch! Make sure to get the plain, original cheerios.
It is a very simple recipe, but I do have a few tricks to share to make sure the bars are not too hard or dry in the FAQs below. This recipe is delicious anytime of year, but it is especially nice if you do not want to bake during the summer heat.

Recipe FAQs
I recommend only using the Cheerios brand original cereal because they are significantly better than the private label brands in my opinion. I also do not recommend using honey nut Cheerios or other sweetened cereals. These bars are already the right sweetness and do not need extra sugar.
These cheerio bars are gluten free as long as you use the Cheerios brand. If you are using a different brand, be sure to check the ingredients if you are making these bars for someone with Celiac disease or someone avoiding gluten. Not all brands of cheerios-type cereal are gluten free.
The key to keeping these bars soft is to only heat the mixture just until the edges barely start to boil. If you overheat it, the bars will become extremely hard once they cool. They will still taste good but it is not ideal.
Yes, this recipe can easily be cut in half for a smaller batch. Instead of a 9x13 inch pan, use an 8x8 inch pan.
