directions

Prepare the cake pans: I preheat the oven to 350°F (175°C) and grease two 9-inch round cake pans, lining the bottoms with parchment paper for easy removal.
Mix the dry ingredients: In a large bowl, I whisk together the flour, both sugars, cocoa powder, baking powder, baking soda, and salt.
Add the wet ingredients: I beat in the eggs, milk, oil, and vanilla until smooth. Then I slowly pour in the hot coffee or water, which deepens the chocolate flavor and loosens the batter—it will be thin, and that’s perfect.
Bake the layers: I divide the batter evenly between the pans and bake for 30–35 minutes, or until a toothpick comes out clean. I let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
Make the buttercream: I beat the butter until creamy, then gradually add powdered sugar and cocoa powder. I drizzle in cream and vanilla to reach the right consistency and flavor, beating until fluffy and smooth.
Assemble the cake: Once the cakes are cool, I level the tops if needed. I spread a generous layer of frosting between them, then frost the top and sides. I decorate however I like—with chocolate curls, berries, or just a swirl of frosting.

Servings and timing

This recipe makes 12–14 slices.
Prep time: 25 minutes
Bake time: 30–35 minutes
Cooling & decorating time: 1–2 hours
Total time: About 2.5–3 hours

Variations

Sometimes I add a layer of raspberry or cherry jam between the cakes for a fruity contrast. I’ve also folded mini chocolate chips into the batter or used a ganache drip over the top. For a mocha version, I add espresso powder to both the batter and frosting.

storage/reheating

I store the cake covered at room temperature for up to 2 days or in the fridge for up to 5. If chilled, I let it come to room temp before serving for the best texture. Slices can be microwaved for 10–15 seconds for that fresh-baked warmth.

FAQs

Can I use Dutch-process cocoa?

Yes, I sometimes use Dutch-process cocoa for a smoother, deeper flavor. I make sure my leavening agents are adjusted accordingly since it reacts differently than natural cocoa.

What can I use instead of coffee?

I use hot water if I prefer to skip the coffee. The coffee doesn’t make the cake taste like coffee—it just enhances the chocolate.

Can I make this cake in advance?

Definitely. I bake the layers a day ahead and wrap them tightly in plastic wrap. I frost the cake the next day for convenience and better flavor.

Can I freeze the cake?

Yes, I freeze unfrosted cake layers for up to 2 months. I thaw them in the fridge overnight before decorating.

How do I get smooth frosting?

I use a bench scraper or offset spatula, and I chill the crumb-coated cake briefly before applying the final layer of buttercream.
