In a stand stand mixer cream butter and sugar until fluffy. Add vanilla and mix well.
Add flour and potato flakes and mix until dough forms a ball.
Gently fold in pecans, chocolate chips, and potato chips.
Using a medium 2oz cookie scoop drop dough onto a greased or lined baking sheet about 2 inches apart.
Using the bottom of a glass (I used a wine glass), dip glass in sugar and press onto the top of the cookie to flatten it into an even layer.
Bake at 350 degrees for 12-15 minutes or until edges are lightly golden brown.
