Preheat oven to 350 degrees. Grease three 9 inch cake pans, line with parchment paper, then grease the parchment. cut around the edge of the cake pans so you have a flat round of parchment in the bottom of the pan.
Whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt and espresso powder together in a large bowl. Set aside.
Using a handheld or stand mixer fitted with the whisk attachment (or you can just use a whisk) mix the oil, eggs, yogurt (or sour cream), buttermilk and vanilla together until combined.
Pour the wet ingredients into the dry ingredients, add the hot coffee, and whisk or beat it all until the batter is completely combined.
Divide the batter evenly between the 3 pans. Bake for 22-25 minutes until a toothpick comes out clean. Remove the cakes from the oven and set on a wire rack to cool completely in the pan.
