Preheat your oven to 350° Fahrenheit. Liberally (take liberties with it!) butter and flour a 10 inch bundt pan (or an angel food cake tube ban). In a small bowl combine sweetened flaked coconut and coconut oil. Mix until combined and briefly set aside. Sprinkle sugar on the bottom of the bundt pan (or tube pan) and sprinkle the sweetened flaked coconut mixture over the sugar. Set the pan aside.
In a medium bowl, combine the all-purpose flour, salt, baking powder and baking soda. Mix briefly with a fork to combine and set aside.
In a measuring cup, combine the buttermilk and coconut milk, stirring briefly.
In a bowl of an electric mixer fitted with a paddle attachment (a hand mixer works here as well) over medium/high speed, cream the sugar, butter, and coconut oil until light and fluffy, about 2-3 minutes. Add eggs one at a time, beating well after each addition. Stop and scrape the mixer. Add the sour cream, vanilla bean paste, and coconut cream. Mix until combined. Stop and scrape the mixer once more to incorporate ingredients.
Reduce the mixer speed to low and alternate the flour mixture and buttermilk/coconut milk mixture, starting and ending with the flour. Mix until ingredients are moistened. If you see flour bits, it's cool. Stop the mixer, remove the bowl and gently fold the batter onto itself about 3-4 times (no more or your cake will be tough), making sure you scrape the bottom of the bowl to incorporate all ingredients.
Place in the oven and bake for 45-55 minutes (depending on your oven situation), or until cake tester or wooden skewer inserted in the center of the cake comes out clean. My cake was done around 52 minutes, but your oven may differ from mine. I suggest you start checking around the 45 minute mark.
Remove cake from the oven and allow it to cool in the pan for about 10 minutes or so. Periodically run a knife around the edges of the pan
to help loosen the cake. After 10 minutes or so carefully remove cake from the pan, scraping the sides, and place in a large cake platter and allow to cool completely before glazing.
