Preheat oven to 350ºF. To prepare the springform pan, cut a piece of parchment paper just slightly smaller than the diameter of the bottom of a 9-inch springform pan. Lay the paper on the bottom of the pan. To prepare the pan so that no water leaks into it while cooking, wrap the pan in foil using 18-inch wide heavy-duty aluminum foil. Place a large square of foil on a flat surface. Place the springform pan in the middle of the foil. Fold up the sides of the foil around the pan. Crimp the foil around the top edges of the pan. Place a second large square of foil underneath the pan, and repeat.
To make the crust, mix together the graham cracker crumbs, brown sugar and cinnamon. Add melted butter and stir to combine. The mixture should look like wet sand. Empty the crust mixture into the prepared pan. Spread crumbs evenly. Using clean hands, or the bottom of a glass, press down firmly against the bottom and up the sides of the pan just a bit. Place pan on a baking tray and bake for about 10 minutes until the crust starts to turn golden around the edges. Remove from the oven and let cool. Reduce heat to 325ºF.
To make the filling, place all ingredients in a blender and blend till completely smooth. Bring 2 quarts of water to a boil. Place the springform pan in a high-sided roasting pan. Pour the filling over the crust and smooth with a spatula. Create a water bath for the cheesecake by pouring the boiling water into the roasting pan so it surrounds the springform pan. Place the roasting pan on the bottom rack (you can also pull out the rack halfway, put the roasting pan on it and then pour the water in if that’s easier), and bake for 1 1/2 hours. Turn oven off and crack the oven door. Let cake stay in the oven for another hour, then remove and cover the pan with foil so that the foil doesn’t touch the cake. Refrigerate overnight. Slice and serve chilled with coconut milk whipped cream or caramel sauce.
To make the chocolate ganache, place chocolate in a medium bowl. Bring coconut cream to a simmer in a saucepan over medium-high heat. Pour the coconut cream over the chocolate and let stand for about a minute then whisk mixture until smooth. Let cool, stirring often, then pour over cake and smooth, if necessary.
