What You’ll Need

For the Chocolate Cake:

3/4 cup (95g) all-purpose flour
3/4 cup (150g) granulated sugar
1/4 cup (25g) unsweetened cocoa powder (Dutch-process preferred)
3/4 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1/2 cup (120ml) hot coffee (or hot water)
1/2 cup (120ml) buttermilk (room temperature)
1/4 cup (60ml) vegetable oil
1 large egg (room temperature)
1 teaspoon vanilla extract

For Rich Chocolate Frosting (Optional):

1/2 cup (115g) unsalted butter (softened)
1/3 cup (35g) cocoa powder
2 1/2 cups (300g) powdered sugar (sifted)
1/3 cup (80ml) heavy cream
1 teaspoon vanilla extract
Pinch of salt

Substitution Notes:

Coffee: Enhances chocolate flavor—use decaf if preferred, or substitute hot water
Buttermilk: Make your own with 1/2 cup milk + 1/2 tablespoon lemon juice
Cocoa powder: Natural cocoa works too, but Dutch-process gives richer color
Oil: Can use melted butter (cool slightly) for slightly denser texture

Step-by-Step Directions

Prep your setup. Preheat oven to 350°F (175°C). Grease a 6-inch round cake pan generously with butter and dust with cocoa powder (not flour) for extra chocolate flavor. Line bottom with parchment paper.
Prepare hot coffee. Brew 1/2 cup strong hot coffee and set aside to cool slightly. This secret ingredient intensifies the chocolate flavor without making the cake taste like coffee.
Whisk dry ingredients. In a medium bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until no lumps remain. Sifting the cocoa powder helps prevent clumps.
Combine wet ingredients. In a large bowl, whisk together the slightly cooled coffee, buttermilk, oil, egg, and vanilla until smooth and well combined.
Mix wet and dry ingredients. Pour the dry ingredients into the wet ingredients and whisk gently until just combined. The batter will be thin—this is exactly what creates the moist texture.
Pour into prepared pan. Transfer batter to the prepared 6-inch pan—it will fill about 2/3 full. Give the pan a gentle tap on the counter to release any air bubbles.
Bake until set. Bake for 23-26 minutes until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The top should spring back lightly when touched.
Cool completely. Let cake cool in pan for 10 minutes, then run a knife around edges and turn out onto a wire rack. Remove parchment and cool completely before frosting—this prevents melting.

Pro Tip: Don’t overbake chocolate cake! It continues cooking from residual heat. A few moist crumbs on the toothpick ensure a fudgy, tender texture.

For the Chocolate Frosting (If Using):

Start with butter base. Beat softened butter for 3 minutes until very light and fluffy. This creates the foundation for smooth, pipeable frosting.
Add cocoa gradually. Beat in cocoa powder on low speed until combined, then increase speed to medium. The mixture will look crumbly at first—this is normal.
Alternate sugar and cream. Add powdered sugar and cream alternately, beating well after each addition. Finish with vanilla and salt, beating until smooth and spreadable.
Frost when cool. Spread frosting generously on completely cooled cake using an offset spatula for professional-looking swirls and peaks.

Expert Tips for Success

Chocolate Cake Mastery:

Room temperature ingredients mix better and create smoother batter
Don’t skip the coffee—it makes chocolate taste more chocolatey, not coffee-flavored
Thin batter is good batter—resist the urge to add more flour
Cool completely before frosting to prevent melting and sliding

Storage & Make-Ahead:

Store unfrosted cake covered for 3 days at room temperature
Refrigerate frosted cake and bring to room temperature 30 minutes before serving
Freeze unfrosted cake for up to 3 months—wrap tightly in plastic, then foil
Best flavor develops after 24 hours as chocolate flavors meld

Troubleshooting Common Issues:

Cake too dense: Don’t overmix batter or use expired leavening agents
Dry texture: Overbaking is the culprit—start checking at 22 minutes
Sunken center: Oven temperature too high or door opened too early
Frosting too thick: Add cream 1 tablespoon at a time until spreadable

Flavor Variations:

Mocha: Add 1 tablespoon instant espresso powder to dry ingredients
Mexican chocolate: Add 1/2 teaspoon cinnamon and pinch of cayenne
Orange chocolate: Add 1 tablespoon orange zest to batter
Mint chocolate: Add 1/2 teaspoon mint extract to frosting

Common Questions

Can I make this without coffee?

Absolutely! Replace coffee with hot water or hot milk. The coffee enhances chocolate flavor without adding coffee taste, but the cake is still delicious without it. You could also use hot chocolate for extra richness.

Why is my chocolate cake dry?

Chocolate cakes can dry out quickly due to cocoa powder absorbing moisture. Make sure not to overbake—start checking at 22 minutes. Also ensure your baking soda and powder are fresh for proper lift and moisture retention.

Can I double this for a layer cake?

Yes! Make two batches for perfect 6-inch layers. You can also split one cake horizontally for thinner layers. Increase frosting recipe by 1.5x for adequate coverage between layers and outside.

What’s the best cocoa powder to use?

Dutch-process cocoa gives the richest, darkest color and mellowest flavor. Natural cocoa works too but may taste slightly more acidic. Both create delicious results, so use what you have on hand.

How do I know when it’s done baking?

The cake should spring back lightly when touched, pull slightly from pan sides, and a toothpick should come out with moist crumbs (not wet batter). Small cakes bake quickly, so start checking at 22 minutes.

Can I make cupcakes instead?

Definitely! This recipe makes 8-10 standard cupcakes. Bake at 350°F for 16-18 minutes. They’re perfect for portion control and freeze beautifully.
