In a large mixing bowl, add eggs butter, buttermilk and mix until fluffy.
Add chocolate cake mix, cocoa powder and mix until just combined. There might be a few lumps and that's perfectly fine. Don't over-mix!
Pour this batter into two greased and floured round cake pans (Dimensions: 8x2), lined with parchment paper. Bake at 350 degrees for 40 minutes or until an inserted toothpick in the center comes out clean.
Allow the cakes to cool to room temperature.
While the cakes are baking and cooling, prepare coconut pecan frosting and ganache.
Trim sides of the cake (optional) and if there is a dome, trim the top so that the cake is flat (required).
Place one cake on a serving dish.
Use a spatula to spread frosting on top.
Drizzle spoonfuls of chocolate ganache.
Then, place the other cake on top and press gently to secure it into place.
Use a spatula to spread frosting on top again.
Drizzle spoonfuls of chocolate ganache again. Enjoy!
