Instructions

Preheat your oven to 325 degrees F. Lightly butter or grease an 8-inch round baking pan and line the bottom with parchment paper.
In a mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
In a separate bowl, whisk the sour cream, vegetable oil, egg, and vanilla until fully blended. Create a well in the center of the dry ingredients and pour in the sour cream mixture. Stir gently until almost combined, ensuring some dry streaks remain.
Add the hot brewed coffee or water to the mixture and stir until smooth. It may seem very runny initially but will come together. A whisk can help if you encounter any lumps.
Pour the batter into the prepared baking pan, spreading it evenly across the surface.
Bake for 35 to 40 minutes, until the center springs back when touched and a toothpick inserted comes out with a few moist crumbs. Let it cool on a wire rack until the pan is cool enough to handle, then invert the cake to cool completely.

Notes

Ensure all ingredients are at room temperature for the best results.
For a richer flavor, use high-quality cocoa powder and dark chocolate.
Store any leftovers tightly wrapped at room temperature for up to three days.
