Preheat the oven to 375 degrees and line a 9x13 baking sheet with parchment paper.
In a stand mixer with beater attachment, add the brown sugar, white granulated sugar, and crisco. Cream together until nice and fluffy, about 2 minutes.
Add the vanilla and eggs. Beat until combined.
In a medium mixing bowl, whisk together the flour, salt, baking soda, and cocoa powder.
Add the flour mixture to the mixer, ½ a cup at a time. As it’s mixing, slowly add more of the flour mixture until it’s all gone. Mix until fully combined.
Add the dark chocolate chips and pecans. Beat for a few seconds or until evenly distributed.
Using a cookie scoop, drop the cookies onto the prepared baking sheet, leaving an inch in between each cookie.
Bake for 8-10 minutes (cookie times can vary from oven to oven) or until the cookies look like they’re almost done.
Pull them out and let them cool on the pan for 5 minutes. Move to a cooling rack.
