Preheat oven to 375 degrees Fahrenheit. Prepare a cookie sheet with parchment paper or cooking spray.

In a large bowl or the bowl of a stand mixer, cream together the wet ingredients, shortening, sugars, egg, and vanilla till light and fluffy. 

In a separate bowl, stir together dry ingredients. 

Slowly add the dry ingredients into the creamed mixture, one large spoonful at a time. Mix well.  

Gently fold in the cup chocolate chips and walnuts. 

Using a cookie scoop, drop dough balls 2 inches apart on your prepared baking sheet.  

Bake for 9 -10 minutes or until the outside of the cookie starts to turn a light golden brown. 

Remove from sheet immediately and transfer to a cooling rack or waxed paper.

Allow to cool for at least 10 minutes before eating. Enjoy!
