Grease and flour a tube pan. Preheat the oven to 325℉.
Sprinkle ½ cup of pecans into the bottom of your prepared pan. This step is optional but we love the flavor and bit of crunch that it adds to the top of the cake.
In a separate bowl whisk the cake flour, baking powder, and salt to combine, set aside for later.
Using an electric mixer (paddle attachment if using a stand mixer), cream the butter on medium speed until smooth. Next, gradually add the sugar and beat until light and fluffy for 3 to 5 minutes.
Add the eggs one at a time, blending after each until the yolk is incorporated.
Add the vanilla extract and coconut extract to the 1 ¼ cup of buttermilk.
With the mixer on low speed, add the flour mixture alternately with the buttermilk to the butter/sugar/egg mixture in the mixing bowl. Begin and end with the dry ingredients. I do three additions of dry, alternating with two additions of wet. Mix on low speed just until incorporated.
Gently fold in the ¾ cup coconut and 1 cup of crushed pecan pieces.
Scoop batter into the prepared bundt pan.
Bake at 325℉ for approximately 1 hour and 10 minutes. The cake is done when the cake springs back when the top is lightly touched and a toothpick comes out clean (or with just a few moist crumbs attached). *Baking times may vary. Start checking as the timer approaches 1 hour. (See notes for details on pan size/type)
This makes approximately 8 cups of batter.
Allow to cool in the pan for 10 minutes before turning out.
