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 bars and frozen yogurt granola berry bites.

With school starting in a couple 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 hangry and ready to eat the entire pantry. I don’t even try asking 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. I love sitting around the kitchen table eating together and listening to all of their school day stories.

One of their favorite snacks are 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 cereals 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

MELT. Add the peanut butter and honey in a medium pot. Cook until smooth, about 3 minutes. Make sure to stir consistently. Remove from heat and add in vanilla.

STIR. Gently mix in the dry cereal until well coated. Then press the mixture into a parchment lined 8×8″ pan.

CHILL. Let chill in the fridge for about one hour before serving. Enjoy!

Tips for Making Cereal Bars

  • Make sure to press down firmly with parchment paper so that they stick together (and not on your hands).
  • Refrigerate the bars for the full hour so they become firm.
  • Use a sharp knife to cut through the bars.
  • Once cut, store in an airtight container in the refrigerator to help keep their shape.
  • Drizzle melted chocolate or stir in some chocolate chips to turn these into a fun kid-friendly dessert.
