In a large bowl, combine the sugar cookie mix, pudding mix, butter and egg until a dough forms. Press into an ungreased 9”x13” baking pan. Bake for 20 to 25 minutes or until set.
Meanwhile, in a large saucepan, combine the caramels and milk over medium-low heat, stirring often until melted and smooth. Remove the pan from the heat and stir in the nuts and vanilla extract.
Pour the caramel mixture over the top of the crust. Sprinkle with the butterscotch chips and let cool completely. Cut into bars. Store in an airtight container. Enjoy!
