I read alot of food blogs. Eating is my hobby. I am not the greatest cook or baker, but once in awhile I will experiment.
I found a recipe for Potato Chip cookies here.
I am not sure how this would taste, I do like the idea of salty and sweet.
We rarely buy potato chips, but who knows I might try this at the holidays.
from her blog
Potato Chip Cookies
3 dozen cookies

2 1/2 cups crushed potato chips* (measure after crushing)
1/2 cup light brown sugar, firmly packed
1/4 cup white sugar
1 egg
1/4 cup milk
1 teaspoon vanilla extract
1 cup flour
1 1/2 teaspoons baking powder
1/2 cup chopped pecans or roasted peanuts

Combine the sugars, egg, milk and vanilla and whisk together to combine in a medium mixing bowl. In a small bowl, stir together the flour and baking powder to combine. Add dry ingredients to batter then mix in the potato chips and nuts. Drop by teaspoonfuls onto a greased baking sheet (or parchment lined sheet) allowing space for the cookies to spread. Bake at 375° for 10 to 15 minutes, or until lightly browned.

* I use Lay's potato chips because they are thin, crispy and very salty. Other chips may work well too, but I've always used Lay's. You can now get Lay's with no trans-fat and while I couldn't work out exactly how much fat and calories are in 2 1/2 cups of potato chip crumbles, there is no addition added fat in the recipe (other than what is in the egg and milk).
