Ingredients
- Dry Ingredients:
- 1 cup (120g) all-purpose flour
- 1/2 cup (45g) unsweetened cocoa powder
- 3/4 cup (150g) granulated sugar
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- Wet Ingredients:
- 1 large egg
- 1/2 cup (120ml) buttermilk
- 1/4 cup (60ml) vegetable oil
- 1 teaspoon vanilla extract
- 1/2 cup (120ml) hot coffee (or hot water)
- 2 ounces (57g) unsweetened chocolate, melted and cooled slightly

Instructions
- Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease and flour a 6-inch round cake pan. You can also line the bottom with parchment paper for easy removal.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- Combine Wet Ingredients: In a separate bowl, whisk together the egg, buttermilk, oil, and vanilla extract.
- Combine Wet and Dry Ingredients: Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix.
- Add Hot Coffee and Melted Chocolate: Gradually pour in the hot coffee (or hot water) and mix until the batter is smooth and thin. Then, gently fold in the melted and slightly cooled unsweetened chocolate.
- Pour Batter into Pan: Pour the batter into the prepared cake pan.
- Bake: Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs attached.
- Cool: Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
- Frost: Once the cake is completely cool, frost with your favorite chocolate frosting.
Tips for Success
Here are some tips to help you achieve the perfect 6-inch chocolate cake:
- Measure Accurately: Baking is a science, so accurate measurements are crucial. Use measuring cups and spoons and level off dry ingredients.
- Don’t Overmix: Overmixing the batter can result in a tough cake. Mix until just combined.
- Use Room Temperature Ingredients: Room temperature ingredients emulsify better, resulting in a smoother batter and a more even bake.
- Use High-Quality Cocoa Powder: The quality of your cocoa powder will significantly impact the flavor of the cake. Opt for a Dutch-processed cocoa powder for a richer, less acidic flavor.
- Melt Chocolate Carefully: Melt the chocolate gently in the microwave in 30-second intervals, stirring in between, or over a double boiler to prevent burning.
- Adjust Baking Time: Baking times may vary depending on your oven. Start checking for doneness around 30 minutes and adjust accordingly.
- Cool Completely Before Frosting: Frosting a warm cake will cause the frosting to melt and slide off. Make sure the cake is completely cool before frosting.
Storage Instructions
Unfrosted Cake: Store the unfrosted cake tightly wrapped in plastic wrap at room temperature for up to 3 days or in the refrigerator for up to 5 days. You can also freeze the unfrosted cake for up to 2 months. Wrap it tightly in plastic wrap and then in foil.
Frosted Cake: Store the frosted cake in an airtight container in the refrigerator for up to 3 days. Let it come to room temperature before serving for the best flavor and texture.

FAQ
Q: Can I use a different type of flour?
A: While all-purpose flour is recommended for this recipe, you can substitute with cake flour for an even softer crumb. However, you may need to adjust the liquid slightly.
Q: Can I use regular milk instead of buttermilk?
A: If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1/2 cup of milk. Let it sit for 5 minutes before using.
Q: Can I use a different type of oil?
A: You can substitute vegetable oil with canola oil or melted coconut oil. Avoid using olive oil, as its flavor can be overpowering.
Q: Can I make this cake ahead of time?
A: Yes, you can bake the cake a day or two in advance and store it tightly wrapped at room temperature or in the refrigerator. Frost it just before serving.
