Preheat the oven to 350ºF (180ºC). Line two large baking sheets with parchment paper.
In a medium bowl, whisk together the flour, cocoa powder, baking soda, salt and cinnamon.
In a large bowl, cream the butter, brown sugar, and sugar together with an electric mixer until light and fluffy.
Beat in the eggs and vanilla in three separate additions, making sure each one is incorporated before adding the next.
On low speed, beat in the flour mixture just until combined.
Fold in the oats, almonds, coconut, cranberries, pistachios and pumpkin seeds.
Place 1 1/4 ounce round portions (about 2 tablespoons) three inches apart on the prepared baking sheets.
Bake until the tops are set and no longer shiny, about 10-12 minutes.
Transfer the cookies to a cooling rack to cool completely.
Combine the melted chocolate and coconut oil in a small deep container, wide enough to fit the width of your widest cookie. Dunk cookies about halfway into chocolate. Top with nuts and seeds.
