What You’ll Need
For the Chocolate Cake:
- 1¼ cups all-purpose flour
- 1 cup granulated sugar
- ⅓ cup unsweetened cocoa powder (Dutch-processed preferred)
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- ½ cup hot brewed coffee (or hot water)
- ½ cup buttermilk, room temperature
- ⅓ cup vegetable oil
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
For Rich Chocolate Frosting (Optional):
- ½ cup unsalted butter, softened
- ⅔ cup unsweetened cocoa powder
- 3 cups powdered sugar
- ⅓ cup milk or heavy cream
- 1 teaspoon vanilla extract
- Pinch of salt
Substitution Notes:
- Buttermilk → regular milk + 1 tablespoon lemon juice (let sit 5 minutes)
- Hot coffee → hot water (coffee enhances chocolate flavor without adding coffee taste)
- Vegetable oil → melted butter (use ¼ cup + 2 tablespoons)
- Dutch-processed cocoa → natural cocoa powder works too
Step-by-Step Directions
- Preheat oven to 350°F (175°C). Grease an 8-inch round cake pan with butter, then dust with cocoa powder, tapping out excess. Line the bottom with parchment paper for foolproof removal.
- Prepare your coffee. Brew ½ cup of strong hot coffee and set aside to cool slightly. If you don’t have coffee, hot water works fine—the cake will still be delicious!
- Whisk dry ingredients. In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until no lumps remain.
- Combine wet ingredients. In a separate bowl or large measuring cup, whisk together the slightly cooled coffee, buttermilk, oil, egg, and vanilla until smooth.
- Mix the batter. Pour the wet ingredients into the dry ingredients and gently whisk until just combined. The batter will be thin—this is exactly what you want for a moist cake!
Pro Tip: Don’t worry about the thin batter consistency—it’s the secret to this cake’s incredibly tender crumb. Resist the urge to add more flour.
- Pour and level. Transfer the batter to your prepared 8-inch pan. Gently tap the pan on the counter a few times to release air bubbles and level the surface.
- Bake to perfection. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached. The top should spring back lightly when touched.
- Cool properly. Let the cake cool in the pan for 10 minutes, then run a knife around the edges and turn out onto a wire rack. Cool completely before frosting—about 1 hour.
For the Chocolate Frosting (If Using):
- Beat the butter until light and fluffy, about 3 minutes with an electric mixer on medium speed.
- Add cocoa gradually. Beat in the cocoa powder until well combined, scraping down sides as needed.
- Alternate dry and wet. Add powdered sugar and milk alternately, beginning and ending with powdered sugar. Beat in vanilla and salt until smooth and spreadable.
- Frost and enjoy. Spread frosting evenly over the completely cooled cake using an offset spatula.

Expert Tips for Success
Temperature Matters: Room temperature ingredients blend more easily, creating a smoother batter. Take eggs and buttermilk out 30 minutes before baking.
Don’t Skip the Coffee: Even if you’re not a coffee drinker, the hot coffee intensifies the chocolate flavor without making the cake taste like coffee. It’s the secret ingredient that separates good chocolate cake from extraordinary chocolate cake.
Proper Pan Preparation: Cocoa powder prevents white flour residue on your dark cake. If you only have flour, that works too—just brush off any visible white spots before serving.
Storage Solutions: Store covered at room temperature for up to 3 days, or refrigerate frosted cake for up to 1 week. Unfrosted cake freezes beautifully wrapped in plastic for up to 3 months.
Moisture Secrets: The thin batter creates steam during baking, which keeps the cake incredibly moist. Don’t add extra flour even if the consistency seems unusual.
Flavor Variations to Try:
- Double Chocolate: Fold in ½ cup mini chocolate chips before baking
- Mocha: Add 1 tablespoon instant espresso powder to the dry ingredients
- Spiced Chocolate: Add ½ teaspoon cinnamon and ¼ teaspoon cayenne for warmth
- Orange Chocolate: Add 1 tablespoon orange zest to the batter
Common Questions
Can I make this without buttermilk?
Absolutely! Mix ½ cup regular milk with 1½ teaspoons lemon juice or white vinegar. Let it sit for 5 minutes until it curdles slightly—this creates the same acidity that makes the cake tender.
Why does my cake have a dense texture?
Overmixing is usually the culprit. Mix just until ingredients are combined—lumps are fine. Also, make sure your baking soda and baking powder are fresh (replace every 6 months for best results).
Can I use this recipe for cupcakes?
Yes! Divide batter among 12 lined muffin cups and bake for 18-22 minutes. You’ll get perfectly portioned individual treats.
What if I don’t have an 8-inch pan?
Use a 9-inch round pan and reduce baking time by 3-5 minutes, checking for doneness with a toothpick. For an 8×8 square pan, the timing stays about the same.
How do I prevent the cake from sticking?
Proper pan preparation is key: grease thoroughly, dust with cocoa powder, and line the bottom with parchment. Let the cake cool for exactly 10 minutes before turning out—too soon and it might break, too long and it might stick.
Can I make this dairy-free?
Replace buttermilk with non-dairy milk mixed with lemon juice, use plant-based oil instead of butter in frosting, and substitute non-dairy milk in the frosting. The cake will be just as delicious!
