Grease 9x13-inch baking dish then pour Fritos corn chips to cover the bottom.

In a microwave-safe bowl, combine the corn syrup and sugar. Microwave on high for 1 minute then stir well. Continue microwaving in 1-minute increments until the sugar mixture comes to a boil, about 3 minutes.

Remove sugar mixture from microwave and stir in peanut butter until smooth.

Pour the peanut butter mixture over the Fritos, trying to cover up all the chips. Do not stir.

Allow to sit for 1 hour until cooled.

If desired, you can melt the chocolate chips in the microwave (30-second intervals, until melted and smooth) and spread over the cooled bars. Tik Tok says this is the best way!
