Preheat the oven to 350 degrees Fahrenheit.
In a large mixing bowl, add the dry ingredients of flour, cocoa powder, espresso powder, baking soda and powder, salt, and brown and white sugar.
Whisk all these ingredients together until combined. Pour in the buttermilk, vanilla extract, and eggs. Whisk or blend with a hand mixer until completely smooth and a thick batter forms.
Add in the boiling water along with the chocolate chips and chocolate pudding mix, whisking to allow the chocolate chips to melt into the batter with the hot water.
Once the batter is smooth, fold in the sweetened shredded coconut and chopped pecans until evenly distributed.
Pour this cake batter into a prepared bundt pan sprayed with baking spray.
