These potato chip cookies are full of so many different textures its like a party in your mouth. First, the edges of the cookie are nice and crispy. The middle of the cookie is soooo soft; think Nestle Tollhouse cookie soft. Classic. Then, you bite into a crunchy, ruffled potato chip! The saltiness pairs so nicely with the sweetness of the cookie, and of course those creamy chunks of chocolate. Finally, the marshmallow fluff swirls in the cookie give these cookies that awesome chewiness that only marshmallow fluff can achieve. Heavenly!
