Heat oven to 350 degrees. In a mixing bowl with paddle attachment, beat butter, granulated sugar and brown sugar together until fluffy. Beat in the egg and vanilla until smooth.
Add the flour, cocoa powder, baking soda and salt to the mixture. Beat until combined.
Add coconut, chocolate and pecans and mix to just combine and bring together.
Drop tablespoon sized pieces onto parchment-lined or silicone-lined baking sheets, about 2 inches apart from each other. Refrigerate for atleast 10 minutes for a firmer dough and thicker cookie result. Then bake for about 10-12 minutes, or until edges are browned.
Remove from oven and allow to cool at room temperature.
