2/3 cup honey

How to Make 3 Ingredient Cheerio Bars

Step 1

Line an 9×13-inch baking pan with parchment paper or wax paper. Leave a little overhang to make removing the bars easier later.

Step 2

In a microwave-safe bowl, combine the honey and creamy peanut butter. Warm in 20 second intervals until the peanut butter mixture is completely smooth and well combined.

If desired, you can add in a teaspoon of vanilla for extra flavor!

Step 3

Place the cheerios into a large bowl. Pour the warm peanut butter mixture over the cereal.

Using a rubber spatula, gently fold everything together until every Cheerio is evenly coated.

Step 4

Transfer the mixture into the prepared pan. Press firmly into an even layer. Lightly grease your hands or place a piece of plastic wrap over the mixture while pressing to prevent sticking.

Step 5

Place the bars in the refrigerator or freezer for 30 minutes until they are hardened fully. Cut into squares.

I store mine in the freezer and they are ready to eat straight out of the freezer. My kids love them like that!

Easy Variations

There are lots of ways to customize this recipe based on what you have at home.

Instead of Honey Nut Cheerios, try:

Plain Cheerios
Peanut Butter Cheerios
Multi-Grain Cheerios

Swap the peanut butter for:

Crunchy peanut butter
Almond butter
Cashew butter
Sunflower seed butter

Keep in mind that some natural nut butters separate more easily, so stir well before measuring.

You can also replace the honey with maple syrup, brown rice syrup, or agave nectar if preferred. Just note that changing the sweetener may slightly affect how firmly the bars set since the amount of honey helps hold everything together.

If you enjoy other cereal treats like Rice Krispies bars, you’ll love this fun twist using Cheerios.

Storage Tips

Once the bars are completely cool, cut them into squares and store in an airtight container in the refrigerator or freezer. Place a sheet of wax paper or parchment paper between layers to keep them from sticking together.
