1/2 cup butter (I use light butter and put it out so it gets soft at room temperature)
1/3 cup granulated sugar
3/4 teaspoons vanilla
1 cup flour
1/3 cup of crushed potato chips (comes out to around 1 ounce of chips. I used low salt Wavy Lays)
1/3 cup chopped walnuts (around 1.5 ounces of nuts)
1 Tablespoon of granulated sugar (when you smash the cookies before they go into the oven--put this sugar in a small flat dish)
Cream the butter, 1/3 cup of sugar, and vanilla until they are well mixed. Add the flour, and mix well. Then add the potato chips and walnuts. Mix it all up really good. Then cover the bowl with plastic wrap, and put it in the refrigerator for around an hour. This will make the dough easy to handle.
Preheat the oven to 350 degrees.
Get your dough and ungreased baking sheets. Roll the dough into little balls, and evenly space around the baking sheet. They say 2 inch balls placed 3 inches apart, but use your eyes and common sense with this one. You don't want the cookies to touch when you smash them.
Put some oil on the outside bottom of a glass. Dip the glass into the 1 Tablespoon of sugar. Press the glass down on a cookie. This flattens the cookie and puts some sugar on it.
Put the cookies into the oven for 12-15 minutes. They won't look brown on top, but you can see the bottom browning. That's when they are done. My cookies took the whole 15 minutes.
After they cool on the sheets for around 7 minutes, take the cookies off and put them in a container, and dust with powdered sugar.
I only got 2 1/2 dozen cookies from this recipe, so if you are feeding a ravening horde of kids, you may want to double or triple the recipe.
