Why You’ll Love This Recipe

  • Speedy and Stress-Free: You only need 15 minutes to whip up a batch from start to finish. All you need is a saucepan, a spatula, and a little parchment—nothing complicated here.
  • Three Simple Ingredients: No tricky shopping list—just butter, marshmallows, and corn pops cereal.
  • Fun to Make, Even More Fun to Eat: It’s almost impossible to mess these up, which makes them perfect for getting kids or beginner bakers involved.
  • Customizable: Want extra gooeyness? Add fewer pops. Prefer a firmer bite? Stir in a little more cereal. The mix is totally in your control.

Ingredients You’ll Need

  • Unsalted Butter: For rich flavor and to keep the bars perfectly soft; salted butter also works but will add a savory edge.
  • Marshmallows (Large): The key to that signature chewy, sticky, sweet texture. Mini marshmallows melt even faster if you prefer!
  • Corn Pops Cereal: The classic choice for a sweet crunch; other puffy cereals can also stand in.
  • Tip: Use fresh cereal for maximum crunch! Stale cereal leads to softer bars.

Variations

  • Chocolate Drizzle: Melt some chocolate and zigzag over the cooled bars for a touch of decadence.
  • Peanut Butter Swirl: Add a big spoonful of creamy peanut butter to the melted marshmallows for incredible depth.
  • Mix-Ins: A handful of mini chocolate chips, rainbow sprinkles, or chopped nuts makes every bite a surprise.
  • Cereal Swap: Try this with other cereal varieties like honey-flavored puffs, toasted rice, or even fruity loops.

How to Make Cereal Bars

Step 1: Prep Your Pan

Line a 9×13-inch baking pan with parchment paper. This will make it a breeze to lift out and cut the bars later. Set it aside while you start the mix.

Step 2: Melt the Marshmallows

In a large pot over medium-high heat, melt the unsalted butter completely. Add the marshmallows, and stir constantly—you want a smooth, lump-free, sticky cloud of sweetness. Be patient and keep stirring to avoid scorching the sugar.

Step 3: Mix in the Cereal

Take the pot off the heat, then pour in your corn pops. Quickly stir everything together until every pop is generously coated. If it looks too sticky and gooey (which, honestly, is amazing), add more cereal half a cup at a time until you reach the texture you prefer.

Step 4: Press and Cool

Spread the mixture into your prepared pan. Use the back of a silicone spatula (spray with a little oil if it’s sticking) to press the mixture evenly and gently—it’s tempting to compact it hard, but a light touch keeps them tender.

Step 5: Slice and Enjoy

Let your cereal bars cool at room temperature for about 2 hours. Then, cut them into squares. Try not to eat them all at once!

Pro Tips for Making the Recipe

  • Stir, Stir, Stir: The secret to silky marshmallow? Keep it moving so nothing burns.
  • Work Quickly: The cereal and marshmallow mixture sets up fast. Have your pan ready and move directly from pot to pan while it’s still warm and pliable.
  • Don’t Overpack: Gently press—smashing the bars down too hard makes them dense instead of delightfully chewy.
  • Oil the Spatula: A little spray or butter on your spatula or hands keeps sticking in check.

How to Serve

Cereal Bars Recipe

These Cereal Bars are perfect for lunchboxes, quick snacks, or wrapping up in parchment as a sweet gift. Pair with a cold glass of milk, mug of hot chocolate, or just a good cup of coffee for grown-ups. They’re also fun on party dessert tables or picnic trays.

Make Ahead and Storage

Storing Leftovers

Keep these bars fresh by storing them in an airtight container at room temperature. They’re best eaten the day you make them—the texture is perfect and crunchy then! After the first day, the cereal may soften a bit, but they’ll still be tasty for another day or so.

Freezing

Cereal bars are not the best candidates for freezing, as the marshmallow texture can change and the cereal often gets chewy or hard.

Reheating

If your bars get a bit firm, a quick zap in the microwave for 5–10 seconds can help restore some gooeyness. Just don’t overdo it!

FAQs

Can I use different types of marshmallows?
Absolutely! Mini marshmallows melt even faster, and flavored ones add fun color and taste. Just make sure you use the same total weight.

Why do my cereal bars turn out hard?
This usually happens if the mixture is pressed too firmly into the pan or if you add too much cereal. Use a light touch and add cereal slowly until you hit your perfect balance.

What’s the best way to cut the bars?
Wait until they’re completely cool. Use a sharp knife greased with a little butter or oil for clean slices. Wipe the blade between cuts for perfect squares.

Can I make these dairy-free?
You can! Use a plant-based butter and check your marshmallows to make sure they don’t contain gelatin if you need them vegan.

Final Thoughts

There’s something magical about transforming three simple ingredients into a pan of sweet, chewy, and totally delightful Cereal Bars. They’re quick, customizable, and guaranteed to make any day a little brighter. Give them a try for your next treat—you might discover they disappear even faster than you make them!

Description

These homemade Cereal Bars are a quick and delightful treat made by mixing buttery melted marshmallows with crisp corn pops cereal, then pressed and cooled to form chewy, gooey bars perfect for snacks or easy desserts.

Ingredients

Units Scale

Base Ingredients

  • 6 tablespoons (84 g) unsalted butter
  • 10 ounce (284 g) bag of large marshmallows
  • 7 cups (196 g) corn pops cereal

Instructions

  1. Prepare the Baking Pan – Line the bottom of a 9×13″ baking pan with parchment paper. Set the pan aside to have it ready for the mixture.
  2. Melt Butter and Marshmallows – In a large pot, melt the butter over medium-high heat. Add the marshmallows to the melted butter. Stir continually, ensuring the marshmallows melt evenly and do not burn. Stirring frequently is key for a smooth, gooey mixture.
  3. Mix in Cereal – Once the marshmallows are melted and combined with the butter, remove the pot from the heat. Immediately pour in the corn pops cereal. Mix thoroughly until all the cereal pieces are coated with the marshmallow mixture. If desired, you can add an extra 1/2 cup of cereal at a time for a less gooey texture.
  4. Spread and Shape – Pour the mixture into your prepared baking pan. Using the back of a silicone spatula, gently press down and evenly distribute the mixture throughout the pan, but do not compress it too much as it can become dense.
  5. Cool and Cut – Allow the mixture to cool in the pan for about 2 hours. Once completely set, lift using the parchment paper and cut into squares to serve.

Notes

  • These bars taste best when eaten the same day, as the cereal will lose its crispness by the next day.
  • Store leftovers in an airtight container to preserve freshness as much as possible.
  • Add extra cereal gradually if you prefer a less gooey bar.
  • Use a silicone spatula lightly greased with butter to prevent sticking while spreading the mixture.
