BEWARE, this recipe is truly decadent. I make it a couple of times a year for special occasions. The finished product is moist and addicting. Yummy! I know it seems like a long process, but it is WELL worth the effort.

Whipping egg whites separately and folding them into the batter at the final stage is the primary mechanical defense against density in this recipe. Trapped air expands inside the oven at 350 degrees Fahrenheit, lifting the heavy whole wheat flour and cocoa solids into a light crumb. Monitor the bake time closely between 20 and 30 minutes, withdrawing the pans the exact moment a wooden toothpick inserted into the center emerges clean. Over-baking dries out the crumb structure irreversibly by evaporating moisture bound by the buttermilk and butter emulsion. While the cake bakes, the cooked milk, sugar, and egg yolk mixture requires continuous stirring over medium heat for approximately 12 minutes until it thickens into a golden base. Allowing this frosting to rest for two to three hours before assembly is mandatory because the starch and dairy proteins need that window to cool and thicken into a honey-like viscosity capable of supporting heavy flakes of coconut and coarsely chopped pecans without sliding off the vertical layers. Precise temperature control when combining the melted German sweet chocolate with the butter and egg yolks prevents premature protein coagulation.
