This was almost as fun to make as it was to eat. That's because the crust is simply made of toasted pecans, maple, coconut oil and salt blitzed up in a food processor. And the dark chocolate mousse filling comes together quickly in one sauce pan on the stovetop. Once the two components are layered into a pie plate, the pie goes into the fridge (or freezer, if impatient) for a few hours to set. No baking involved, naturally free of gluten and dairy, and only simple ingredients required.
