Turn oven to 350 degrees, line the bottom of 2 8-inch cake pans with parchment paper, and then butter and flour them
I used my 8-inch cast iron skillet, because i didnthave any cake pans, be creative right!
In one bowl place all the dry ingredients, flour, sugar, cocoa, baking soda, baking powder, espresso powder, and salt. With a whisk mix until well combined
In another bowl add, buttermilk, oil, eggs, and vanilla
With your mixer on low speed, mix the wet ingredient 3 to 4 minutes
With your mixer still on low speed, slowly add in the dry ingredients, scraping down the sides of the bowl until combined
Slowly add in your hot coffee, and mix just until combined, do not over mix
Divide between your pans, and place on the center rack of your oven
Check after 25 minutes, you are looking for a toothpick inserted in the center comes out clean, if it is not done check every 5 minutes, it could take 35 to 40 minutes
When done, remove from oven and place on wire racks for 30 minutes
after 30 minutes remove from pans and let them sit on the racks until completely cool
