Preheat the oven to 350°F. Prepare your pan by greasing the bottom and sides of a round or square 8-inch cake pan with coconut oil. Line the bottom of the pan with a piece of parchment paper so the cake is easy to remove later.
Melt the chocolate and coconut oil together in a large bowl over simmering water (double boiler). After melted, stir in the coconut milk until combined. Remove bowl from the heat and stir in the maple syrup, hazelnut extract, vanilla, and salt.
Using a food processor, grind the hazelnuts until finely ground. Then using a spatula, mix the meal with the chocolate mixture in the bowl.
In a separate bowl, beat the eggs with a handheld or stand mixer for a couple of minutes until fluffy and they double in volume. Then using a spatula, gently mix the eggs into the chocolate/hazelnut mixture until everything is combined.
Pour the batter into the prepared pan and wrap the sides of the pan with aluminum foil. Place the pan in a deep baking dish and fill it halfway with hot water. Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Be sure to not over bake it. Allow the cake to cool in the pan for a few minutes then place it in a serving plate and top it with the Chocolate Fudge sauce and chopped hazelnuts. Store pie in the fridge - it will last for about 2 weeks.
*To toast and skin the hazelnuts, place them in a baking pan and bake in the oven for around 10 minutes at 350°F, or until lightly colored. Wrap nuts in a kitchen towel and rub to remove the skins.
