Preheat oven to 350°F.

In a bowl, add your all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Mix dry ingredients (preferably with a whisk).

In a separate bowl or glass measuring cup, add your hot water and espresso powder and mix till completely incorporated.

In that bowl add your buttermilk, vegetable oil, and vanilla extract. Mix till almost incorporated (doesn’t have to be completely mixed since oil won’t mix with water).

Pour the solution of buttermilk, vegetable oil, vanilla, hot water, and espresso powder into the bowl of dry ingredients.

Mix till fully incorporated.

Add in your 2 eggs, 1 at a time.

Lastly, add your white vinegar.

Butter your pans, this will make about 4 6” layers or 2 8” layers.
