Ingredients You’ll Need
Getting the perfect balance of flavor and texture comes down to a few simple but essential ingredients. Each one plays a starring role, from the rich butter adding creaminess to the marshmallows that provide that ooey-gooey magic, and finally the corn pops cereal bringing that signature crunch and light sweetness.
- Unsalted butter (6 tablespoons/84 g): Adds richness and helps bind everything together while keeping the flavor clean and buttery.
- Large marshmallows (10 ounces/284 g): These are the heart of the recipe, melting down to that perfect stretchy, gooey consistency that holds the cereal bars together.
- Corn pops cereal (7 cups/196 g): The crunchy, airy cereal that gives the bars their delightful texture and mild sweetness with every bite.
How to Make Cereal Bars Recipe
Step 1: Prepare the Baking Pan
Start by lining the bottom of a 9 by 13-inch baking pan with parchment paper. This simple step makes all the difference when it’s time to remove and cut your cereal bars without any mess or sticking. Setting it aside keeps you organized and ready for the gooey mixture.
Step 2: Melt Butter and Marshmallows
In a large pot over medium-high heat, melt your butter completely. Once melted, add the marshmallows right away. Stir constantly to ensure the marshmallows melt evenly and smoothly blend with the butter. This part requires some attention—keep stirring to avoid burning and to create that perfectly creamy marshmallow base.
Step 3: Mix in Cereal
Remove the pot from the heat as soon as the marshmallows have melted, then quickly stir in the corn pops cereal. Mix thoroughly so every piece is coated in the marshmallow goodness. For a less gooey bar, you can gradually add a little more cereal, but mixing thoroughly is key to an even texture throughout.
Step 4: Spread and Shape
Pour your luscious cereal mixture into the prepared pan. Using the back of a silicone spatula, press it down gently and spread it out evenly. Don’t press too hard—leaving some airiness helps keep the bars light and chewy rather than dense.
Step 5: Cool and Cut
Let the bars cool and set for about 2 hours at room temperature. Once firm, lift the whole batch out using the parchment paper lining. Cut into 12 squares or whatever size suits your craving. These bars hold their shape beautifully and are ready to enjoy or pack up for later.
How to Serve Cereal Bars Recipe

Garnishes
While these bars are fantastic all on their own, you can sprinkle some fun toppings for an extra pop of flavor or color—think mini chocolate chips, rainbow sprinkles, or a drizzle of melted peanut butter or chocolate. Each garnish adds a little personal flair and indulgence perfectly suited for sharing with friends or kids.
Side Dishes
Cereal bars pair wonderfully with fresh fruit or a simple glass of cold milk for a balanced snack. Serve alongside a cup of hot tea or coffee for an afternoon treat that feels both comforting and satisfying without being too heavy.
Creative Ways to Present
For parties or gifting, cut the cereal bars into bite-sized pieces and stack them in a decorative tin or wrap individually in colorful parchment paper. You can even layer bars with whipped cream and fresh berries in clear jars for a fun twist on dessert parfaits that are sure to impress.
Make Ahead and Storage
Storing Leftovers
Simply store the cereal bars in an airtight container at room temperature. They’ll stay fresh and chewy for up to 3 days, making them a great option for quick snacks throughout the week.
Freezing
If you want to keep them for longer, wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag. Frozen cereal bars will last up to a month and thaw quickly at room temperature when you’re ready for a sweet treat.
Reheating
While these bars are perfect enjoyed cold or at room temperature, warming them slightly in the microwave for 10-15 seconds can bring back that fresh-from-the-pan gooeyness, especially nice on a chilly day.
FAQs
Can I use a different cereal instead of corn pops?
Absolutely! While corn pops are ideal for their light texture and sweetness, you can experiment with rice cereal, puffed wheat, or your favorite crunchy cereal for a slightly different flavor and texture.
Is it possible to make these cereal bars vegan?
Yes! Swap the butter for a plant-based margarine or coconut oil and use vegan marshmallows, which are available in many specialty stores. This way, you can enjoy the recipe while sticking to a vegan lifestyle.
How do I make the bars less sticky?
Simply add an extra half cup of cereal or let the bars set longer before cutting to ensure they firm up nicely. Just be careful not to compress the mixture too much when pressing it into the pan.
Can I add mix-ins like nuts or chocolate chips?
Definitely! Stir in chopped nuts, mini chocolate chips, or dried fruits along with the cereal to customize with your favorite flavors and textures that make each batch uniquely yours.
What’s the best way to cut these bars without them crumbling?
Use a sharp knife and cut the bars once they have fully cooled and set. For cleaner cuts, you can lightly grease the knife or warm it under hot water, then dry before slicing.

Making this Cereal Bars Recipe is such a joyous experience because it’s simple, quick, and downright delicious.
