Preheat oven to 350. Line cookies sheets with parchment.

Cream the butter and sugar together until smooth and creamy. Beat in the egg yolk and vanilla; scrape down the sides of the bowl as needed.

With the mixer on low, gradually add the flour.

Fold in the potato chips, chocolate chips and sprinkles.

Use a 2 TBSP cookie scoop to scoop the dough onto the prepared sheets. Press more sprinkles and crushed potato chips into the top of each cookie.

Bake for 15 minutes or so until the edges are browned. Let the cookies set on the cookie sheets for a minute or two, then transfer to a wire rack to cool completely.
