Instructions

Preheat the oven to 325 degrees F and prepare an 8-inch round baking pan by lightly buttering or greasing it. Line the bottom with parchment paper.
In a mixing bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, and salt, whisking until evenly blended.
In a separate bowl, whisk together the sour cream, oil, egg, and vanilla until well combined. Create a well in the center of the dry ingredients, then pour in the sour cream mixture. Mix until just combined with a few dry streaks remaining.
Add the hot coffee or water to the mixture, stirring until the batter becomes smooth. Use a whisk if necessary to help combine thoroughly.
Transfer the batter into the prepared pan, ensuring it spreads evenly over the base.
Bake for 35 to 40 minutes until the center feels springy. Check with a toothpick to see if it comes out with a few moist crumbs. Once baked, cool in the pan on a wire rack until it's safe to touch, then invert to cool completely.

Notes

Ensure that the vegetable oil and sour cream are at room temperature for better incorporation into the batter.
For a richer flavor, use high-quality dark chocolate for garnish or as an ingredient.
You can substitute coffee with hot water, but coffee enhances the chocolate flavor significantly.
