Ingredients You’ll Need
This recipe only calls for a handful of ingredients, but each one plays a vital role in the magic of Frito Bars. It’s almost unbelievable how something so simple can taste so fun and unexpected! Let’s break down what you’ll need and why each matters:
- Fritos corn chips (1 bag, 9.25 oz): These classic, crunchy corn chips provide the salty backbone, the satisfying crunch, and that unmistakable savory flavor that makes these bars so special.
- Peanut butter (1 cup): Smooth, creamy peanut butter is the glue that binds everything together, adding richness and a nutty depth that can’t be beat.
- Granulated sugar (1 cup): This is where the sweetness comes in, balancing the saltiness of the chips and giving the bars their crave-worthy flavor.
- Corn syrup (1 cup): Essential for giving the topping its signature gooey, glossy texture; also helps hold the bars together beautifully.
- Cooking spray: Makes it easy to get your Frito Bars out of the pan in perfect squares with no sticking—don’t skip it!
How to Make Frito Bars
Step 1: Prep Your Pan
Start by reaching for a 13 × 9 inch baking dish and giving it a good misting with cooking spray. This step is key—nobody wants to wrestle with sticky bars, and this will make lifting them out a breeze later on.
Step 2: Layer the Fritos
Take your bag of Fritos and pour them evenly into the prepared baking dish. Spread them out with your hands or a spatula, making sure they reach all the corners. A nice, even layer ensures each bar gets the perfect ratio of crunchy chips to sweet topping.
Step 3: Make the Peanut Butter Mixture
In a medium saucepan, combine the peanut butter, granulated sugar, and corn syrup. Place the pan over medium heat and stir steadily with a wooden spoon or silicone spatula. Keep mixing until everything is melted together and the mixture is smooth, silky, and just starting to bubble.
Step 4: Pour and Spread
Working quickly, pour the hot peanut butter mixture all over the Fritos. Aim for even coverage, then use a spatula (or the back of a spoon) to gently nudge and spread the mixture so it coats as much of the chips as possible. The warmth will start to seep into the Fritos and help the magic happen!
Step 5: Chill and Set
Pop your pan into the refrigerator and let it set for about 1 hour—or until the topping feels firm to the touch. This cooling time lets everything meld together into sliceable, snackable bars.
Step 6: Slice and Serve
Once firm, use a sharp knife to cut the Frito Bars into squares or rectangles. The contrast between the crispy Fritos and glossy topping is pure bliss! Now, they’re ready for munching.
How to Serve Frito Bars

Garnishes
For a little extra pizazz, try sprinkling the tops with a pinch of flaky sea salt, some mini chocolate chips, or a dusting of powdered sugar before the bars cool completely. These little touches add fun texture and flavor pops that make each bite even more exciting.
Side Dishes
Since Frito Bars strike the perfect sweet and salty balance, they pair well with a fruity side—think fresh berries, pineapple wedges, or a simple fruit salad. For parties, you might want to serve them alongside ice-cold milk or a tangy lemonade to balance the richness.
Creative Ways to Present
If you’re serving these at a gathering, stack your Frito Bars on a big platter for snackable appeal, or wrap individual bars in parchment and tie with twine for adorable grab-and-go treats. For dessert buffets, try cutting them into bite-sized cubes and inserting toothpicks for easy handheld snacking!
Make Ahead and Storage
Storing Leftovers
Keep any leftover Frito Bars in an airtight container at room temperature for up to three days. If your kitchen gets warm, store them in the fridge to maintain their shape and keep the peanut butter layer nice and firm.
Freezing
These bars actually freeze surprisingly well! Place squares in a single layer on a baking sheet to freeze until solid, then transfer to a zippered bag or airtight container. They can be frozen for up to two months; just let them sit at room temperature for about 15 minutes before serving.
Reheating
While you don’t need to reheat Frito Bars, if you prefer them a little gooier, try letting refrigerated bars sit out for a few minutes before serving. This softens the topping slightly and brings out that luscious, chewy texture.
FAQs
Are Frito Bars gluten-free?
Most regular Fritos are naturally gluten-free, but always check the label to make sure your chips—and the other ingredients—meet your dietary needs.
Can I use a different nut butter?
Absolutely! Almond butter or sunflower seed butter can be swapped in for peanut butter if you’re avoiding peanuts, though it will change the flavor a bit (deliciously so).
Why did my bars turn out too hard?
If the sugar-corn syrup mixture was cooked too long or too hot, it can harden and make the bars firm instead of chewy. Next time, just heat until everything’s combined and smooth.
Can I add chocolate or other add-ins?
You sure can! Melt a handful of semi-sweet chocolate chips and drizzle on top once the bars are set, or stir in butterscotch chips or chopped pretzels for extra crunch and flair.
Do Frito Bars have to be refrigerated?
They don’t have to be, but chilling helps them set and makes slicing neater. If your kitchen is cool, you can safely keep them at room temperature.
