Cream together butter, shortening, and sugars until light and fluffy.

Add eggs and vanilla extract, then beat well to combine.

In a separate bowl, combine flour and baking soda.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Gently fold in the crushed potato chips and butterscotch morsels.

Drop by rounded tablespoons onto an ungreased cookie sheet.

Bake in a preheated oven at 375°F (190°C) for 8 to 10 minutes, or until golden brown.

Let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
