If you like your chips sweet and salty, these cookies will satisfy.
Preheat the oven to 375ºF. Line 2 baking sheets with parchment.
In the bowl of a stand mixer, cream together the butter, granulated sugar and brown sugar on medium-high speed until light and fluffy, 3 to 5 minutes. Add the vanilla and eggs and beat on medium speed until just combined. Add the flour, baking soda and salt, then mix on low speed until just combined. Stir in the chocolate chips and 2 cups of the crushed potato chips. Put the remaining 2 cups crushed potato chips in a shallow bowl.
Roll the dough into 2-inch balls, then roll them in the remaining potato chips so they are completely coated. Place the cookies 2 inches apart on the prepared baking sheets and bake until golden, 12 to 15 minutes. Let cool for 5 minutes, then transfer to a wire rack to cool completely.
