Store bought cereal bars and granola bars certainly have their place in our snack cabinet, but homemade peanut butter cheerio bars are superior in my opinion. You can use any cereal but I love me some Cheerios. I use the good old original version with minimal added sugar and 4 grams of fiber per serving. Honey will give it plenty of sweetness, and peanut butter is the perfect binder.

What makes a good snack? I like to incorporate a source of carbohydrate like cereal, fruit, or crackers for energy and brain power! Then to make it more filling and satisfying, I add a protein or fat, like peanut butter, cheese, Greek yogurt, or hummus. 

You could stop at just those three ingredients for peanut butter cheerio bars but I like to add hemp hearts and chia seeds. These two ingredients will add more protein, fiber, and healthy fat. A few extra ingredients to make a more filling and nutrient dense snack. 

If you have a peanut allergy, I highly suggest either using wow butter or sunbutter for these cereal bars. You can use any nut butter. So go with what you like. Feel like meal prepping a big batch? Store them in the freezer until you’re ready to eat!
