In just a few minutes, you can make seriously delicious Cereal Bars made with just three super simple ingredients. They’re crispy, flavorful, and a perfect snack for kids.
I recently had a box of cereal that my kids completely lost interest in and in an effort to avoid wasting food, I turned it into these delicious bars. They were so much better than I expected, they stay crisp for days and days, and they are so fast to pull together.
I love making snacks from pantry staples and transforming basic ingredients into super yummy recipes.
This is a nutritious kids snack that can double as an easy breakfast bar too!

To make this recipe you’ll need:

Here’s a look at the process involved in making this recipe. Scroll down to the bottom of the post for the full recipe.
- Stir the peanut butter and honey together.
- Add to a bowl with the cereal. Mix.

Frequently Asked Questions
I’ve made these with both Cherrios and Trader Joe’s Joe’s O’s. The Cheerios hold up longer (they stay crisper), but both work. You can explore other options too.
These will store for up to 5-7 days in the fridge if wrapped well. They hold up when stored in the fridge and served cold. They soften at room temperature a little.
You can make them with almond butter or sunflower seed butter. They should work exactly the same with a GF O cereal, though there may be some variation in how long they stay crispy.

3-Ingredient Cereal Bars
Made with just 3 pantry staples, these bars make an excellent kids snack. They hold their shape best when stored in the fridge and served cold.
- 1/2 cup smooth natural peanut butter (like Smuckers Natural)
- 1/2 cup honey (or brown rice syrup)
- 3 1/2 cups O cereal (like Cheerios)
- 1/2 teaspoon vanilla extract, optional
Line an 8×8-inch baking sheet with parchment paper, leaving a 2-inch overhang on two sides (which will make lifting the bars out when it’s time to slice them easy).
Add the peanut butter and honey to a large heat-safe bowl. Warm in the microwave for 15-30 seconds, or until easy to stir. (This may not be necessary if you keep your peanut butter and honey at room temperature.)
Stir together to combine.
Add the cereal and vanilla, if using, to the bowl. Stir gently, but thoroughly, using a wooden spoon or spatula. It may take a minute or two to get the mixture evenly coated.
Press mixture into the prepared baking sheet to fit into the corners.
Chill for at least 20 minutes. Remove from the fridge, lift out using the parchment paper, and slice on a cutting board.
Wrap each bar in plastic wrap (optional) and store in an airtight container in the fridge.
- I like to wrap each bar, then store in a storage bag or airtight container in the fridge. You can skip the plastic wrap, but do store them in an airtight container.
- Store in the fridge for up to a week. (They may last a little longer than that, but they may soften slightly.)
- You can make this nut-free with sunflower seed butter.
- You can also add a little vanilla extract for additional flavor if you like.
