In the bowl of a stand mixer fitted with a paddle attachment, cream together the butter, shortening and sugars until smooth.
½ cup unsalted butter, ½ cup vegetable shortening, ¾ cup granulated sugar, ¾ cup brown sugar
Add the egg and vanilla extract, continuing to mix until just combined
2 teaspoon vanilla extract, 2 eggs
Add the all-purpose flour, soda, cinnamon and salt. Mix until completely blended.
2 ½ cup all-purpose flour, 1 teaspoon baking soda, 1 teaspoon cinnamon, ¼ teaspoon salt
Fold in the chocolate chips and chopped pecans until completely combined.
1 ½ cup semi-sweet chocolate chips, 1 cup chopped pecans
Scoop out approximately 2 tablespoon of dough and roll it into a ball. Place on the parchment paper lined baking sheet and repeat the process, allowing enough space for the cookies to spread. Bake for 8-10 minutes. Allow the cookies to cool slightly before transferring to a cooling rack.
