Becky, YIKES! Hard to believe three people didn’t catch that through creation, writing and editing, but it happens. Thank you SO much for bringing that to my attention! I’ve fixed both the recipe and the copy of the post, so that they pecans are added after the addition of the dry ingredients. I can’t thank you enough for taking the time to comment and let me know. It is greatly appreciated!

CC, you should be able to add some chocolate chips without any issue however I would reduce the amount of pecans called for as your dough to pecan and chocolate chip ratio would be off.
Since the recipe calls for 1 ½ cups pecans, I would reduce that amount to at least 1 cup and add ½ cup of chocolate chips or even better, I’d recommend 3/4 cup pecans and 3/4 cup chocolate chips.
Whatever you do, I’d love for you to report back and let us know as others may be interested in doing the same.
Enjoy them!
