Preheat oven to 375F. Line a muffin tin with paper liners!
In a small mixing bowl, mix together 1/2 cup of bran cereal and boiling water. Allow mixture to cool to room temp then whisk in melted coconut oil and egg.
In a large mixing bowl, whisk together flour, sugars, baking soda, baking powder and salt. Create a well in center of dry ingredients. Pour in buttermilk then stir to combine. Finally, stir in the raisins, 1 cup coconut flakes, softened bran mixture, and remaining bran cereal.
Scoop a heaping 1/4 cup of batter into each muffin cup. Top batter with a sprinkle of remaining toasted coconut flakes. Bake for 20 to 25 minutes or until tops are golden brown and/or a toothpick inserted in the center comes out clean. Remove from heat, cool muffins in the pan on a rack for 15 minutes before removing the muffins from the pan.
