Preheat the oven to 350°F. Line a cookie sheet with parchment paper. Set aside.
In a large mixing bowl, beat together butter and sugars. Add vanilla and egg, and mix until smooth.
Mix in cocoa powder, salt, and baking soda. Add flour and mix well.
Fold in chocolate chips, caramel chips, and chopped pecans. Use a spoon or cookie scoop to make 1-inch balls of cookie dough and place them 1-inch apart on the cookie sheet.
Bake in the oven for 10-14 minutes. Remove and allow to cool on a cooling rack.
Notes
If you don’t have caramel chips,you can also cut up pieces of caramel candy as a replacement.
