What You’ll Need
For the Chocolate Cake:
- 1¾ cups all-purpose flour (spooned and leveled)
- ¾ cup unsweetened cocoa powder (Dutch-process preferred)
- 1½ cups granulated sugar
- 1½ teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 large eggs (room temperature)
- 1 cup buttermilk (or regular milk with 1 tbsp lemon juice)
- ½ cup vegetable oil (or melted butter)
- 2 teaspoons vanilla extract
- 1 cup hot coffee (or hot water for milder flavor)
For Simple Chocolate Frosting (Optional):
- 6 tablespoons unsalted butter (softened)
- ⅔ cup unsweetened cocoa powder
- 3 cups powdered sugar
- ⅓ cup milk
- 1 teaspoon vanilla extract
Substitution Notes:
- Cocoa powder: Natural cocoa works, but reduce baking soda to 1 teaspoon
- Buttermilk: Regular milk + 1 tablespoon vinegar or lemon juice
- Coffee: Hot water works fine, but coffee intensifies chocolate flavor
- Oil: Can use melted butter (cooled slightly) for richer flavor
- Sugar: Can reduce to 1¼ cups for less sweet preference
Step-by-Step Directions
- Preheat oven and prep pan. Heat oven to 350°F (175°C). Grease an 8×8-inch baking pan with butter or cooking spray, then line with parchment paper for easy removal. Lightly dust with cocoa powder instead of flour for extra chocolate flavor.
- Mix dry ingredients. In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt until well combined. Make sure no cocoa lumps remain—sift if necessary.
- Combine wet ingredients. In a separate bowl or large measuring cup, whisk together eggs, buttermilk, oil, and vanilla until smooth and well blended.
- Create the batter. Pour wet ingredients into dry ingredients and stir until just combined. The batter will look thick at this point—don’t worry!
Pro Tip: Don’t overmix once you add the liquid ingredients. A few lumps are better than a tough cake!
- Add hot coffee gradually. Slowly stir in the hot coffee until batter is smooth. The batter will be quite thin—this is exactly what you want for a moist cake. The coffee enhances chocolate flavor without making it taste like coffee.
- Pour and bake. Transfer batter to prepared pan and gently tap on counter to release air bubbles. Bake for 28-32 minutes, or until a toothpick inserted in center comes out with just a few moist crumbs attached.
- Cool properly. Let cake cool in pan for 15 minutes, then turn out onto wire rack if desired, or cool completely in pan before frosting.
Baker’s Secret: The cake will continue cooking slightly from residual heat, so don’t overbake—slightly underdone is better than dry!

Expert Tips for Success
Storage Solutions: Store covered at room temperature for up to 4 days, or refrigerate frosted cake for up to 1 week. Unfrosted cake freezes beautifully for up to 3 months—wrap individual squares in plastic wrap for easy portion control.

- Double chocolate: Fold in ½ cup chocolate chips before baking
- Mocha version: Add 2 tablespoons instant coffee powder to dry ingredients
- Spiced chocolate: Add ½ teaspoon cinnamon and pinch of cayenne for Mexican hot chocolate vibe
- Mint chocolate: Add ½ teaspoon peppermint extract and fold in crushed chocolate mint cookies
Texture Enhancements:
- Extra fudgy: Replace ¼ cup oil with additional egg yolk
- Lighter crumb: Substitute ½ cup buttermilk with sour cream
- Denser celebration cake: Add ¼ cup additional cocoa powder and reduce flour by ¼ cup
Moisture Secret: Brush cooled cake with coffee simple syrup (equal parts coffee and sugar, heated until dissolved) for professional bakery-level moisture!
Troubleshooting Common Issues:
- Cake cracking on top: Oven temperature too high—use oven thermometer to verify accuracy
- Sunken center: Don’t open oven door before 25 minutes, and check baking powder freshness
- Dry texture: Don’t overbake—start checking at 28 minutes
- Bitter taste: Check cocoa powder freshness and don’t skip the coffee/hot water
Common Questions
Can I make this without coffee?
Absolutely! Replace the hot coffee with an equal amount of hot water. The coffee doesn’t make the cake taste like coffee—it just intensifies the chocolate flavor. Hot water will still create a wonderfully moist cake.
Why is my chocolate cake not very chocolatey?
This usually comes down to cocoa powder quality and freshness. Use high-quality unsweetened cocoa powder and replace it every 12-18 months. Dutch-process cocoa provides deeper flavor than natural cocoa powder.
Can I bake this in a different pan size?
Yes! For a 9×9 pan, reduce baking time to 25-28 minutes. For cupcakes, fill liners ⅔ full and bake 18-22 minutes. For a 9×13 pan, increase recipe by 1.5x and bake 25-30 minutes.
How do I know when it’s perfectly done?
Look for edges that just start to pull away from pan sides, and a toothpick that comes out with a few moist crumbs—not wet batter, but not completely clean either. The top should spring back lightly when touched.
Can I make this dairy-free?
Definitely! Use non-dairy milk (almond, oat, or soy work well), and stick with vegetable oil instead of butter. The cake will be just as moist and delicious.
What’s the best cocoa powder to use?
Dutch-process cocoa powder (like Hershey’s Special Dark) gives the richest flavor and deepest color. If using natural cocoa powder, the cake will be slightly lighter but still delicious.
