Preheat oven to 350 degrees and prepare a 9x13 baking dish with baking non stick spray. You can line the dish with foil for easy removal, if you do this then spray the foil lining with baking non-stick spray.
In a large bowl, combine the butter, granulated sugar and brown sugar and mix until well combined.
Add in the eggs and vanilla and mix until well combined.
Slowly add in parts of the flour, mixing in between, until all of the flour is mixed in. Stir in the chocolate chips, caramel bits and pecans.
Spread the dough into your prepared pan. Top with a few extra chocolate chips, caramel bits and pecans if you would like, for presentation.
Bake for 25-30 minutes, until the edges turn golden brown. Cool completely before cutting.
