Prepare the Oven: Set your oven to 350°F (175°C) and line baking sheets with parchment paper or lightly grease them.
Cream Butter and Sugar: In a spacious mixing bowl, beat the softened butter and sugar together until the mixture is light, fluffy, and well-combined.
Add Vanilla and Egg: Mix in the vanilla extract and egg, beating until fully incorporated.
Combine with Flour: Gradually add the flour to the butter mixture, stirring until a soft dough forms.
Add Potato Chips: Gently fold in 4 cups of potato chips, being careful not to crush them too much. The chips add a delightful texture and flavor to the cookies.
Shape the Cookies: Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Lightly press a few pieces of the remaining potato chips onto the tops of each cookie for extra crunch and presentation.
Bake: Place the cookies in the oven and bake for 10-12 minutes, or until the edges are a light golden brown.
Cool and Enjoy: Let the cookies sit on the baking sheets for 5 minutes to firm up, then transfer them to a wire rack to cool completely.
