In a large mixing bowl, cream together the sugars and butter.
Add the vanilla and one egg at a time and combine.
Add the flour, salt, baking powder and baking soda. Combine thoroughly. Scrape the sides and bottom of the bowl occasionally with a rubber spatula.
Add the chocolate chips and Heath bar pieces. Mix only until it's combined.
Scoop out cookie dough using an ice cream scoop and place them on a parchment lined sheet pan. Leave enough space as they will spread a bit. (I get 6 cookies on a half sheet pan)
Bake in a preheated 375 degree F oven for about 18-20 minutes or until golden brown. Once the cookies are spread out a bit, as they cook, bang the pan a few times. (This will make them spread out and become crunchy on the edges, yet chewy on the inside) They may look a little under-cooked, but they continue cooking after you remove them from the oven and will set perfectly. Rotate your pans in the oven once, during the baking process. Let the cookies cool for 5-10 minutes before removing them from the baking sheet.
Notes
If you make smaller cookies they will take less time to cook. These are jumbo sized cookies.
