Preheat oven to 220 degrees. Grease bundt pan and 9-inch baking pans with butter but i used olive oil cooking spray and set aside.
Heat up water in a small pot and once its boiling hot place a plate with the white and dark chocolate chips into it and melt then set aside
In the large bowl of a standing mixer, stir together flour, sugar, cocoa, baking soda, and salt, eggs, buttermilk, canola oil, yogurt, mix chocolate chip and vanilla extract and beat until smooth about 5 minutes. Remove bowl from mixer and stir in hot coffee with a rubber spatula or a spoon. Batter will be very runny; please note that is not a problem
Pour batter evenly between the two pans and bake on middle rack of oven for about 25 minutes, until toothpick inserted in center comes out clean, remove from the oven
Allow to cool 5 minutes in pans before placing in a plate or stand if you are not frosting you can serve. yum yum all the way
