Peanut Butter Cheerio Bars

Peanut Butter Cheerio Bars are my go-to, quick and easy after school snack.  This cereal bar recipe is no-bake and only requires three ingredients.

With only a few weeks left before it’s time for back-to-school, I am busy planning lunch ideas and stocking up on snacks and treats.  Last year I had a hard time finding foods my kiddos would eat and not just come back home with the majority of everything I packed still in the lunch box. 

So this summer we spent a lot of time in the kitchen (and the grocery store!) coming up with winning combinations together.  My girls are currently loving this Roasted Red Pepper HummusHomemade Spaghettios, and Kid-Friendly Fruit Sushi.

I love creating recipes based on items that we keep stocked at all times, and peanut butter and honey are obvious pantry staples!  My kids eat peanut butter by the spoonful, but we also use it in my Classic Peanut Butter Cookies and Peanut Butter M&M Cookies.  I use honey in this savory Honey Chipotle Meatballs recipe and as a delicious Honey Lime Dressing with fresh fruit.

These Peanut Butter Cheerio Bars were a hit with all of my kiddos.  Bonus: with only three ingredients they were easy enough for little hands to help make.  Sometimes we like to trick this cereal bars recipe up and make these Chocolate Caramel Cheerios Bars.

I love brownies and bars for a special lunch box treat because they’re generally low mess, don’t require utensils, and are easy to transport.  These Salted Caramel Blondies might be my all time favorite!  Cookies, like these Classic Peanut Butter Cookies or this No Bake Peanut Butter Oatmeal Cookies, are another great option!


Three Ingredient Cereal Bars- perfect for the lunchbox!

Could this be made with Sunbutter or Almond Butter instead of Peanut Butter?

Hi Ariel, I haven't tried this personally... but I believe in theory it should work fine. Please let me know if you do try it!

You can double the recipe for a 9 in X 13 in pan. Also, if you use honey nut O’s the honey can be decreased to 1/4C. The bars will still be sweet, but not too sweet. I love making this easy cereal bar recipe!

Love this recipe. Easy and healthier than using marshmallows. I used crunchy peanut butter and it worked fine. Thanks.
