Ingredients – Peanut Butter Fritos
Before we start, here’s what you’ll need to make these yummy peanut butter bars:
- 4 cups of Fritos corn chips (you can crush them lightly if you like)
- 1 cup creamy peanut butter (smooth works best)
- 3 cups mini marshmallows
- 1/2 cup unsalted butter
- 1 teaspoon vanilla extract (optional, but adds nice flavor)
- 1/4 teaspoon salt (only if your peanut butter isn’t salted)

Step by Step Process – Peanut Butter Fritos
Let’s jump right into how you can make these bars quickly and easily.
Step 1: Prepare Your Pan
Take a square baking dish or pan (about 8×8 inches works well). Line it with parchment paper or lightly grease it with butter. This will help you take the bars out easily when they are ready.
Step 2: Melt Butter and Peanut Butter
In a large saucepan, add the butter and peanut butter. Heat on low to medium heat, stirring constantly. Keep stirring until both butter and peanut butter melt together into a smooth, creamy mixture. This usually takes about 3 to 5 minutes. Be careful not to burn it!
Step 3: Add Marshmallows
Once the butter and peanut butter are melted, add the mini marshmallows to the pan. Keep stirring until the marshmallows melt and everything combines into one sticky, gooey mixture. This step makes the bars sweet and helps everything stick together.
Step 4: Add Vanilla and Salt
Now, add the vanilla extract and salt (if you’re using unsalted peanut butter). Stir well to mix the flavors evenly.
Step 5: Mix in the Fritos
Turn off the heat. Add the Fritos corn chips to the marshmallow-peanut butter mixture. Stir gently but quickly to coat all the chips with the sticky mix. Try not to crush the chips too much — you want that crunchy texture!
Step 6: Press Into Pan
Pour the mixture into your prepared pan. Use a spatula or your hands (wet your hands so it’s less sticky) to press the mixture down evenly. Press firmly but gently, so the bars hold together well when they cool.
Step 7: Let It Cool
Put the pan in the fridge or leave it on the counter to cool and set. It usually takes about 1 to 2 hours. Once firm, cut into squares or bars.
Step 8: Serve and Enjoy!
Now your Frito Peanut Butter Bars are ready! Enjoy them as a snack or share with your friends and family. They keep well in an airtight container for several days.
