Combine almonds, cocoa powder, coconut oil and maple syrup in your food processor or blender. I used my blender.
Blend it all for almost 10-15 minutes. Do turn off the machine for a few seconds in between, so it doesn't get too heated up.
You should get a pasty sort of a mixture, like a nut butter. Taste and adjust for sweetness. Remember, as the mixture will cool, it won't taste as sweet as its tasting now.
Add the pumpkin seeds and pistachios if you're using. Scrape out in a flat dish, 6" in diameter. Spread it evenly and sprinkle any toppings of your choice. I used pumpkin seeds and smoked sea salt.
Refrigerate for 3-4 hours till set firmly. Cut into small cubes and enjoy!
