In the bowl of a stand mixer with the paddle attachment, cream the butter and sugars until fully mixed and fluffy.
Add in the egg, beating until combined, then add the vanilla extract and peanut butter and beat until incorporated.
In a separate bowl, mix together the flour, baking soda, and salt, then add the dry mixture into the wet mixture and beat until just combined.
Gently fold in the chocolate and potato chips until evenly dispersed through the cookie dough.
Use a cookie scoop to evenly form 12-14 balls of dough. Chill the dough balls in the fridge for at least 2 hours or covered overnight.
Preheat the oven to 350ºF and prepare a baking sheet with parchment paper.
Bake for about 15 minutes, or until golden. If desired, gently press down on the tops of each cookie with the bottom of a glass or another flat surface to flatten the cookies slightly after baking.
Use a round cookie cutter or a large cup to scoot the cookies into even circles, then let them rest at room temperature for at least 5 minutes to finish baking before serving.
