- Total Time: 55 minutes
- Yield: 1 cake (12 slices)
Description
A rich, ultra-moist dark chocolate cake layered with velvety chocolate ganache. Perfect for birthdays, holidays, or pure chocolate indulgence.
Ingredients
1 3/4 cups all-purpose flour
3/4 cup unsweetened dark cocoa powder
2 cups granulated sugar
2 tsp baking soda
1 tsp baking powder
1 tsp salt
2 large eggs
1 cup buttermilk
1/2 cup vegetable oil
2 tsp vanilla extract
1 cup hot brewed coffee (or hot water)
**For the ganache frosting:**
1 1/2 cups heavy cream
12 oz dark chocolate (chopped or chips)
1 tbsp unsalted butter (optional)
Instructions
1. Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans.
2. In a large bowl, sift together flour, cocoa powder, sugar, baking soda, baking powder, and salt.
3. Add eggs, buttermilk, oil, and vanilla. Mix until just combined.
4. Carefully stir in hot coffee until batter is smooth. It will be thin.
5. Divide batter between pans and bake for 30–35 minutes, or until a toothpick comes out clean.
6. Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.
7. For ganache, heat cream until simmering. Pour over chocolate and let sit 2 minutes.
8. Whisk until smooth. Add butter if using for extra shine.
9. Let ganache cool slightly until spreadable.
10. Frost the cooled cake layers, stacking and covering sides evenly.
11. Chill slightly before slicing for clean layers.
Notes
• Hot coffee enhances chocolate flavor without making it taste like coffee.
• Make ahead: Cake layers can be wrapped and frozen for up to 1 month.
• Add a pinch of sea salt on top for a bakery-style finish.
• For cupcakes, reduce bake time to 18–20 minutes.

Why You’ll Love This Ultimate Dark Chocolate Cake
Rich Flavor Profile That Impresses Everyone
This cake isn’t just chocolate—it’s a chocolate revelation. Using high-quality dark cocoa powder creates depth that milk chocolate simply can’t match. I’ve watched friends who claimed they “weren’t dessert people” close their eyes in bliss after tasting it. The slight bitterness of dark chocolate balances perfectly with the sweetness, creating a sophisticated flavor that’s never cloying. What makes it truly special is how it pairs with everything from coffee to red wine, making it versatile enough for any occasion from casual gatherings to elegant dinner parties.
Perfect Texture That Stays Moist for Days
The velvety crumb of this cake is what keeps people coming back for seconds (and thirds). Unlike some chocolate cakes that dry out overnight, this one stays impossibly moist for days—if it lasts that long in your home! The secret lies in the combination of buttermilk and coffee, which not only enhances the chocolate flavor but also creates that tender texture that melts in your mouth. I’ve had guests text me three days after a party to tell me they’re still enjoying leftover slices. The frosting forms a slight crust while staying creamy underneath, creating a textural experience that’s simply divine.
Essential Tips & Tricks
Getting the Perfect Chocolate Flavor
The quality of cocoa makes all the difference in this Ultimate Dark Chocolate Cake. I learned this lesson the hard way after once using cheap cocoa powder that left the cake tasting flat. Invest in Dutch-processed cocoa for that deep, complex flavor. Another game-changer? Adding a tablespoon of instant espresso powder to the batter—you won’t taste coffee, but it magically intensifies the chocolate notes. Don’t skip the vanilla either; it rounds out the flavor beautifully. For an extra dimension, try adding a splash of bourbon or a teaspoon of orange zest to the batter. Check out my New York Cheesecake with Berry Twist for more flavor-boosting techniques.
Mastering the Mixing Method
The room temperature ingredients rule isn’t just baking snobbery—it’s science! Cold eggs or butter can cause the batter to separate or become lumpy. I set everything out about an hour before I start baking. When mixing, resist the urge to overbeat the batter after adding flour, as this develops gluten and results in a tougher cake. Instead, mix just until the ingredients are incorporated—a few tiny lumps are actually good! For the silkiest frosting, beat the butter for a full 3-5 minutes before adding other ingredients. This creates tiny air pockets that make the frosting light and spreadable while still rich.
Serving Ideas & Creative Variations
Seasonal Twists to Keep It Fresh
Transform this versatile base recipe with seasonal additions that highlight the dark chocolate flavor. In summer, I love serving it with fresh raspberries or a tart cherry compote that cuts through the richness. Fall calls for warming spices—try adding cinnamon and a touch of cayenne to the batter for a Mexican chocolate variation that’s cozy and complex. Winter holidays? Add crushed peppermint to the frosting for a festive touch. Spring brings opportunities for floral notes—a touch of lavender in the frosting or a side of candied violets elevates this cake to something truly special. Just like my Easy Chocolate Cream Pie, these seasonal adaptations keep familiar recipes exciting.
Presentation Ideas That Wow
Even a simple chocolate cake becomes a showstopper with thoughtful presentation. For casual gatherings, I dust the top with cocoa powder through a doily for an elegant pattern that takes seconds. For special occasions, try a dramatic drip effect with ganache poured over the frosted cake. Chocolate curls made by dragging a vegetable peeler across a chocolate bar create beautiful decoration with minimal effort. Individual mini cakes served on vintage plates make dinner guests feel extra special. Don’t underestimate the power of a cake stand—elevating your creation (literally) signals to everyone that something extraordinary is about to be enjoyed.
Storage & Troubleshooting Guide
Keeping Your Cake Fresh
The proper storage of this Ultimate Dark Chocolate Cake ensures every slice tastes as good as the first. At room temperature, use a cake dome or inverted bowl to protect it for up to 3 days. The frosting actually creates a seal that helps preserve moisture. For longer storage, refrigeration works beautifully—just bring slices to room temperature before serving to revive the flavors and texture. If freezing (yes, it freezes wonderfully!), wrap individual slices in plastic wrap, then foil, for up to 3 months. This method has saved me countless times when unexpected guests arrive and I need an impressive dessert in minutes.
Fixing Common Baking Issues
Even experienced bakers encounter troubleshooting moments. If your cake sinks in the middle, your oven temperature might be off—invest in an oven thermometer for accuracy. Cakes that stick to the pan despite greasing? Try lining with parchment paper as insurance. For frosting that’s too soft to work with, a quick 10-minute chill in the refrigerator firms it up perfectly. If your cake layers bake unevenly, use cake strips (or make your own from damp kitchen towels wrapped in foil) around the pans. These simple solutions have rescued many of my baking projects from disaster to delight.
Frequently Asked Questions
Can I make this Ultimate Dark Chocolate Cake ahead of time?
Absolutely! The cake actually improves with 1-2 days of rest as flavors deepen. Make it up to 3 days ahead and store at room temperature under a cake dome, or freeze frosted or unfrosted layers for up to 3 months.
What’s the best cocoa powder to use?
Dutch-processed cocoa gives the richest flavor and darkest color. Brands like Valrhona, Guittard, or Droste are excellent choices. Natural cocoa works too but produces a slightly different flavor profile and lighter color.
Can I make this cake without coffee?
Yes! While coffee enhances chocolate flavor without adding coffee taste, you can substitute hot water or hot chai tea for a different flavor dimension. The hot liquid is what helps bloom the cocoa powder.
Is this cake too rich for children?
Most children love this cake despite the dark chocolate. The sweetness balances the intensity perfectly. For younger palates, consider a milk chocolate frosting instead of dark chocolate.
How can I make this recipe gluten-free?
Replace all-purpose flour with a 1:1 gluten-free baking blend containing xanthan gum. The texture will be slightly different but still delicious—just be careful not to overmix.
