Homemade Cereal Bars

During the school year, we love to have lots of easy and delicious snacks on hand. These cereal bars are one of our favorite after-school snack recipes, along with granola, granola bars and frozen yogurt granola berry bites.

With school starting in a couple of weeks, I thought I would share one of my favorite childhood after-school snacks. I don’t know about you, but when my kids get home from school they are hungry and ready to eat the entire pantry. It is hard not to ask them about their day until their bellies are happy. Once they’ve had a good snack, they’re ready to tell me about their day. It is always rewarding sitting around the kitchen table eating together and listening to all of their school day stories.

One of their favorite snacks is these homemade cereal bars. My 3-year-old is peanut butter obsessed and loved making these with me! If you saw my Instagram story last week, you may remember when she dipped her entire hand into the peanut butter jar and then took a big gulp of milk after. She definitely keeps me on my toes, but I always love having her by my side.


The best part about these cereal bars is that you can use your favorite cereal to make them. You can also add some of your favorite mix in’s like peanuts or chocolate chips.

  • Peanut butter: The peanut butter is the ‘glue’ that holds these cereal bars together. You could use any type of nut butter (cashew, almond, etc.), however, I’ve found that peanut butter tastes the creamiest and holds together the best.
  • Honey: The honey adds the perfect touch of sweetness to these cereal bars. If you don’t have honey on hand, you could use maple syrup too.
  • Dry cereal: There are tons of different cereal options that will work in this recipe. You can use your favorite cereal or something that’s already in your pantry.
  • Vanilla: I like to add a dash of vanilla to help enhance the flavor, too.

How to Make Cereal Bars

Easy cereal bars are perfect for making a quick snack or delicious treat for your family or feeding a crowd! They are a simple one-pot recipe that is always delicious and kids’ favorites!

Tips for Making Cereal Bars

Follow these simple tips to make sure that your easy cereal bars are combined well, firm from the cold, and stored properly. These bars are just what you need to have on hand when you have kiddos ready for a snack!

  • Tip. Make sure to press down firmly in a baking dish with parchment paper so that they stick together (and not on your hands).
  • Firm. Refrigerate the bars for the full hour so they become firm.
  • Cut. Use a sharp knife to cut through the bars.
  • Cereals. Try other cereals like rice krispies, lucky charms, or what I used, these honey nut cheerios.
  • Substitute peanut butter. Try almond butter or sunflower seed butter for other alternatives.
  • Store. Once cut, store them in an airtight container in the refrigerator to help keep their shape.
  • Dessert. Drizzle melted chocolate or stir in some chocolate chips to turn these into a fun kid-friendly dessert.

“Delicious and my 2 year old approves too. Easy to alternate ingredients with what ever cereal I had on hand and I used half sugar free maple flavoured syrup too :)”

Recipe FAQs

Are cereal bars a healthy snack?

Some cereal bars are labeled healthy snacks. These bars are on the healthier side with natural sugars but they do have a sweetness to them that does make them have some sugar from the cereal itself.

What holds cereal bars together?

For this homemade cereal bar recipe, the honey really holds the cereal together combined with the peanut butter. They are both like glue that sticks together. Some cereal bars contain marshmallows to help keep them together too.

How long do homemade cereal bars last?

These cereal bars will keep in an airtight container or ziptop bag in the refrigerator for up to one week. Already have the bars sliced into square or long rectangle shapes to make grabbing one out of the fridge a breeze.
