3 Ingredient Peanut Butter & Honey Cereal Bars


Here’s a perfect no-bake back-to-school snack/dessert, the ingredients for which you most likely already have in your kitchen; especially if you have kiddos.


I bought a huge box of toasted whole grain oats cereal (basically Cheerios) from Trader Joe’s a few weeks ago, with Lily in mind. I place a handful on her high chair tray every morning, and enjoy watching her rake palmfuls towards her mouth… though most end up on the floor. She hasn’t yet mastered her pincer grasp, but when she starts working on it, the O’s will be perfect for practicing.

Neither John nor I are big cold cereal eaters, and since Lily is going through the box very slowly, I decided to incorporate the O’s into a recipe.


Although these cereal bars are definitely kid-friendly, they’re not for tots under the age of one. If babies under 12 months of age eat honey, they could develop Botulism.


Sorry Lil’… these are for Mommy and Daddy for the time being ;).



3 Ingredient Peanut Butter & Honey Cereal Bars

by Lauren Zembron (adapted from Honey-Peanut Squares)

Prep Time: 10 minutes

Cook Time: 3 minutes

Keywords: simmer breakfast snack dessert peanut butter bars

Ingredients (9 bars)

  • 1/2 cup crunchy natural peanut butter, well-stirred
  • 1/2 cup honey
  • 3 cups toasted whole grain oats cereal (I used Trader Joe’s O’s)


Line an 8 x 8 inch square pan with parchment.

Combine peanut butter & honey in a large saucepan and set over medium heat. Heat until mixture just starts to simmer, about 2-3 minutes, stirring. Remove from heat and stir until mixture is well-combined.

Stir in cereal until evenly coated. Pour mixture into prepared pan, cover with parchment, and press firmly. (Edited to add: A pastry roller will help to firmly and evenly pack down the mixture so the bars hold their shape). Chill in the refrigerator for 1 hour. Cut into bars. Store individually wrapped in the refrigerator.

    1. Yes, because it will still harden up once in the refrigerator, also add sultanas, diced dried apricot,dates ,nutmeg, cinnamon, pine nuts,peanuts,walnuts,cashews,pistachio etc

  1. Would it be possible to use golden syrup or regular syrup instead o f honey. My honey is nearly empty? My substitute says to use sugar and a liquid?

  2. Can you freeze these bars? And how long are they good refrigerated ? Btw I made a double batch this weekend and these are so easy and delicious :) just finished eating one now!

    1. Hi Dana! My apologies for not getting back to you sooner. I’m sure you can freeze the bars. They will probably stay good in the fridge for up to two weeks. I’m so glad you are enjoying them!

  3. This sounds perfect and so healthy! Thanks for the recipe.

    Thanks, also, for explaining–most sites don’t–why honey isn’t good for children under 1. The issue with botulism is real and scary.

    However, since you wrote this post, things have changed immensely regarding allergies (and peanuts are, technically, a legume and so not a nut). Before your post, the US government had already retracted their recommendation to wait until children are older before giving them peanuts, nuts, and other possible allergens. They had seen a tremendous rise in those allergies after that advice was given, but weren’t sure what people should do.

    Recent studies, since this post, have indicated that even earlier exposure is key to avoiding allergies. Children should be exposed to peanuts, nuts, shellfish/fish, soy, wheat, and other potential allergens as soon as they are served solid foods. In particular, some studies show that eating wheat as soon as possible (even at 5 months, though most authorities say starting solids before six months is inadvisable) is key to avoiding a gluten intolerance or allergy, even in individuals prone to those issues.

    Bottom line: give these potential allergens to your kids early on.
