Blend the dates with the hot water until smooth.
Add the oil, maple syrup, and cocoa powder, and blend until well combined.
In a large bowl, mix together the oats, nuts, and seeds.
Pour the chocolate mixture over the dry ingredients and stir until everything is evenly coated.
Spread the mixture evenly onto a baking tray lined with parchment paper.
Bake for 25–30 minutes.
Remove the granola from the oven, gently break it into small clusters with a spatula, then return it to the oven with the door slightly ajar and bake for another 10 minutes.
Allow the granola to cool completely before storing.
