Why This is the Best Chocolate Cake Ever
There are thousands of chocolate cake recipes out there, but this one stands out for a few key reasons:

- Unbelievably Moist – Thanks to a secret ingredient, this cake stays soft and moist for days.

The Secret to an Ultra-Moist Cake
What makes this cake exceptionally soft and moist? A combination of buttermilk and coffee. Buttermilk tenderizes the crumb, while coffee enhances the chocolate flavor without making the cake taste like coffee.
Ingredients You’ll Need
For the Cake:
- 1 ¾ cups (220g) all-purpose flour
- 2 cups (400g) granulated sugar
- ¾ cup (75g) unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 2 large eggs
- 1 cup (240ml) buttermilk
- ½ cup (120ml) vegetable oil
- 2 teaspoons vanilla extract
- 1 cup (240ml) hot brewed coffee
For the Chocolate Ganache Frosting:
- 1 cup (240ml) heavy cream
- 8 oz (225g) semi-sweet chocolate, finely chopped
- 1 tablespoon unsalted butter (for extra shine)
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease two 9-inch (23cm) round cake pans and line them with parchment paper.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Step 3: Add Wet Ingredients
Add eggs, buttermilk, oil, and vanilla extract to the dry ingredients. Mix until just combined.
Step 4: Incorporate the Coffee
Slowly pour in the hot coffee while stirring continuously. The batter will be thin, but that’s exactly how it should be!
Step 5: Bake
Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
Step 6: Make the Ganache
Heat the heavy cream in a saucepan until it just begins to simmer. Pour it over the chopped chocolate and let sit for 2 minutes. Stir until smooth, then add butter for a glossy finish. Let the ganache cool slightly until it thickens to a spreadable consistency.
Step 7: Frost and Assemble
Place one cake layer on a serving plate. Spread a generous amount of ganache over the top, then place the second layer on top. Cover the entire cake with the remaining ganache, smoothing it out with a spatula.
Step 8: Enjoy!
Slice and serve! This cake pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream.
Pro Tips for the Perfect Chocolate Cake
- Don’t Overmix – Overmixing can make the cake dense. Stir until just combined.
- Use High-Quality Cocoa – The better the cocoa, the richer the chocolate flavor.
- Room Temperature Ingredients – Ensures even mixing and a smoother batter.
- Make Ahead – This cake actually tastes better the next day as the flavors deepen!
- Storage – Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
Variations to Try
1. Chocolate Orange Cake
Add 1 tablespoon of orange zest to the batter for a citrusy twist.
2. Peanut Butter Chocolate Cake
Spread a layer of peanut butter between the cake layers before frosting.
3. Mocha Cake
Increase the coffee to 1 ½ cups for a stronger coffee flavor.
4. Gluten-Free Option
Substitute all-purpose flour with a gluten-free 1:1 baking blend.
5. Vegan Option
Replace eggs with flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water), and use almond milk with 1 tablespoon vinegar instead of buttermilk.
