In a large bowl, cream the butter and sugars with an electric mixer until fluffy. Add the vanilla and eggs and mix well, approximately 3 minutes on medium speed. Scrape down the sides of the bowl.
In a separate large bowl, whisk together flour, cornstarch, baking soda, and salt. With the electric mixer on low, slowly add in the bowl of dry ingredients until dough forms. Do not over mix. (approximately 1 minute).
Hand stir in the remaining ingredients except for the potato chips (stir in caramels, chocolate chips and pretzels). After these ingredients are mixed in, lightly fold in the potato chips and be gentle to maintain some of the chip's form.
Form a loose ball with the dough and wrap tightly with saran wrap. Place the dough in the fridge for 1 hour.
After an hour in the fridge prepare cookie dough for baking. Heat oven 350 degrees. Spray cookie sheets with cooking spray. Use a standard ice-cream scooper to scoop out cookie dough and roll it into a ball with your hands. Place the balls on the cookie sheet approximately 2 inches apart. Bake cookies for 11-12 minutes.
Let the cookies cool for 10-15 minutes before serving.
