Preheat oven to 325 degrees F (if not already). Grease and lightly flour a bundt pan.
Sprinkle ½ cup of chopped, buttered pecans evenly in the bottom of the prepared bundt pan. (You will still have 1 cup remaining for the batter).
In a medium bowl, whisk the cake flour, baking powder, baking soda, and salt for 30 seconds. Set aside
In another bowl, add the buttermilk, vegetable oil and coconut extract. Set aside.
In the bowl of your mixer, add the softened butter and mix at medium speed until smooth. Gradually add the sugar and continue to mix on medium speed for 3 to 5 minutes until lightened in color and fluffy.
Add the eggs one at a time, mixing after each until the yellow of the yolk has blended.
With the mixer on low speed, alternately add the flour mixture and buttermilk mixture, beginning and ending with the dry ingredients (3 additions of dry ingredients and 2 of liquid).
Mix just until incorporated. Be careful not to over-mix.
Fold in the sweetened flaked coconut and one cup of chopped pecans.
Scoop the batter into the prepared bundt pan, which has been sprinkled with ½ cup of chopped pecans.
Bake at 325 degrees F for 45 minutes or until a toothpick inserted in the center comes out clean or with just few crumbs attached. Baking times can vary depending on pan & oven. Peek in as the end time approaches, and add additional time in small increments if needed.
Allow the cake to cool in the pan for 10 minutes on a wire rack before turning out.
